Furthermore, the various components shown or described herein for any specific application of this invention can be varied or altered as anticipated by this invention and the practice of a specific application or embodiment of any element may already be widely known or used in the art or by persons skilled in the art or science; therefore, each will not be discussed in significant detail.




The terms “a”, “an”, and “the” as used in the claims herein are used in conformance with long-standing claim drafting practice and not in a limiting way. Unless specifically set forth herein, the terms “a”, “an”, and “the” are not limited to one of such elements, but instead mean “at least one”.





FIG. 1

shows a vehicle


100


with an internal combustion rotary and reciprocating engine


102


within the vehicle. Again although the term engine is used throughout as the embodiment illustrated, this invention applies equally to pumps and compressors.





FIG. 2

is a cross-sectional view of one embodiment of four cylinders of an engine contemplated by this invention.

FIG. 2

illustrates an embodiment of this invention wherein first cylinder set


113


includes a first cylinder and opposing second cylinder, each cylinder comprising a proximal end (


143


for the second cylinder) open to its opposing cylinder and a terminal end having a transfer port


132


&


142


, each transfer port


132


&


142


being disposed to alternately form a passageway with the intake port and exhaust port in the end plate


110


or


111


.




The first cylinder set


113


and the second cylinder set


114


rotate about central axis


115


of the engine. Rear end plate


110


and front end plate


111


provide intake ports, exhaust ports and a spark plug


133


housing in the embodiment shown. The front end plate


111


and rear end plate


110


are stationary while the first cylinder set


113


and the second cylinder set


114


rotate relative to the end plates and around central axis


115


.




The rotation of the cylinder sets


113


and


114


around central axis


115


is driven by the piston set, cylinder set and crank set or system illustrated in the figures.




The first cylinder set


113


includes a first cylinder


130


with an internal cavity


131


, terminal end


134


with transfer port


132


being disposed to form passageways with intake and exhaust ports and spark plugs


133


in rear end plate


110


.




Second cylinder


140


is in opposed relation to first cylinder


130


and

FIG. 2

illustrates internal cavity


141


to second cylinder


140


, proximal end


143


which may be open and transfer port


142


at the terminal end of second cylinder


140


.

FIG. 2

illustrates transfer port


142


aligned with an exhaust port in front end plate


111


to allow exhaust gasses


148


to exit through exhaust manifold


149


.




First piston set is illustrated within first cylinder set in

FIG. 2

, showing first piston head


135


with piston face


136


and piston rod


137


, the first end of piston rod


137


being mounted to piston head


135


. Second piston is mounted within cylinder


140


and shows piston head


151


with piston face


152


, and piston rod


147


. A first end of piston rod


147


is mounted to piston head


151


.




In the first piston set in the preferred embodiment shown, the first piston and the second piston are operatively attached or integral such that they move together during the operation of the embodiment of the engine shown.




The first cylinder set


113


and first piston set serve to drive the crank set or crank system illustrated in this embodiment. The piston set, as shown more fully in other figures, includes a circular base aperture in the piston configuration between the first piston and the second piston, the circular base aperture is disposed to receive a circular base rotatably mounted within the circular base aperture about a transverse crank set axis, shown as item


117


in FIG.


2


. The circular base


160


has crankpin


161


eccentrically mounted therein or thereon. Crankpin gear


163


, preferably a spur gear, is mounted in a fixed relationship to crankpin


161


such that they move together in a fixed relationship.




Internal gear


162


(or second gear) has internal teeth which are configured to mate with external gear teeth on crankpin gear


163


such that crankpin gear


163


rotates within internal gear set


162


, as shown more fully in later figures.




Crankpin


161


is eccentrically mounted within first outercrank module


165


and eccentrically mounted within first inner crank module


167


. The drive or crank force from the piston set causes crankpin


161


to rotate about transverse crank axis


117


, thereby forcing rotation of first outer crank module


165


and first inner crank module


167


. Mounted to first outer crank module


165


is an outer crank module gear


166


which rotates with first outer crank module


165


. As first outer crank module


165


and outer crank module gear


166


rotate, the external gear teeth on outer crank module gear


166


mate and interact with gear teeth on ring gear


245


(shown more fully in later figures) to cause rotation of first cylinder set


113


and second cylinder set


114


about central axis


115


. Ring gear


245


is more fully shown in later figures but is stationary.




As crankpin


161


rotates, it also causes first inner crank module


167


to rotate, and first inner crank module


167


has inner crank module gears


171


thereon (which may be integral or attached thereto). First inner crank module


167


likewise is forced to rotate about crank set axis


117


. Inner crank module gears


171


mate with gears


169


on drive shaft bearings


174


to also force rotation of first cylinder set


113


and second cylinder set


114


about central axis


115


. Drive shaft bearings


174


rotates about central axis


115


. This thereby provides two points of contact or gear interaction for first cylinder set to provide rotation about central axis


115


and similarly, there are two points of gear interaction or contact to drive second cylinder set


114


about central axis


115


.




It should be noted that while inner and outer crank modules are identified, used and preferred in the embodiment of the invention illustrated, they are not necessary to practice the invention. There are other ways to eccentrically and rotatably mount the crankpin


161


relative to a point on the piston set and relative to the outer crank module gears


166


and


223


, to allow for the combined motion illustrated.




Drive shaft


116


has drive shaft gear set


162


with gear teeth


168


which interact with first inner crank module


167


gear


171


to allow the crank set to cause rotation of drive shaft


116


.




It will be appreciated that the two cylinders within first cylinder set


113


, and the components thereof, operate similarly to the two cylinders in second cylinder set


114


, all combining to drive the rotation of the cylinder sets about central axis and to drive and rotate drive shaft


116


. It will further be appreciated that while the section view in

FIG. 2

only shows four cylinders, this is only one embodiment, and four more cylinders may be added in similar fashion to the configuration at 90 degree offset to the existing four cylinders.




On the lower side of

FIG. 2

, second cylinder set


114


components are illustrated.

FIG. 2

shows third cylinder


200


with internal cavity


204


, transfer port


203


and intake


201


from intake manifold


202


. Piston head


205


, the third piston head, is similarly configured to fourth piston head


211


, and both, as described relative to first cylinder set


113


. Fourth cylinder


206


includes internal cavity


207


and transfer port


210


.





FIG. 2

further illustrates stabilizing stub shaft


170


for first cylinder set


113


and second stabilizing stub shaft


224


for second cylinder set


114


. Second cylinder set


114


interacts with the crank set shown with the following components illustrated: second inner crank module


221


with second inner crank module gears


250


.




Further shown in

FIG. 2

are second outer crank module


222


with second crankpin


213


eccentrically mounted therein and eccentrically mounted on circular base


212


. It is preferable that crankpin


213


be integral or unitary with circular base


212


, although it is not necessary to practice this invention.





FIG. 2

further illustrates second outer crank module


222


with second outer gear


223


rotating with second outer crank module


222


. Similarly to first outer gear


166


mating with ring gear


245


, second outer gear


223


likewise mates with gear teeth on ring gear


245


to also cause rotation of the cylinder sets about central axis


115


.

FIG. 2

also illustrates central block


230


about the first cylinder set


113


and the second cylinder set


114


. Face plate


209


is also shown in

FIG. 2

but more fully illustrated in later figures. In an embodiment of this invention the face plate


209


may be spring loaded or force biased to assist in the sealing of ports interacting with the transfer ports of the cylinders.





FIG. 2

shows face plate


209


within the end plates and as shown more fully in

FIG. 22

, as well as port plate


219


or valve plate, which is also shown in

FIGS. 4-11

. While not necessary, it is preferable to use port plates


219


and face plates


209


for manufacturing and/or sealing reasons, among others. The port plates


219


may be generally configured and shaped similar to the face plates


209


, only with porting apertures. Bias forces may be utilized between port and face plates and end plates to achieve the desired sealing for any particular embodiment.




In

FIG. 2

it will be appreciated that driveshaft mount


240


may be fixed to the rear end plate


110


and front bearing mount


241


may be fixedly mounted to front end plate


111


, with the invention not being restricted to any one particular application.




It will be appreciated by those of ordinary skill in the art that the basic components of this engine, pump or compressor may be adapted for use with diesel fuel as well as other fuel such as gasoline.




It should also be noted that in another embodiment contemplated by the invention, the framework and consequently the end plates, are stationary, and the port plates


219


rotate relative to the framework, end plates and the block


230


. In this embodiment, intake and exhaust ports in the end plates would preferably be utilized in combination with the port apertures in the port plates


219


to accomplish the intake and exhaust functions of the invention. In this embodiment, it would not be necessary to rotate the block


230


and those components related to the rotation of the block


230


would not be necessary. The intake and exhaust functions accomplished as part of the valving would be accomplished by rotating other members such as the port plates


219


as explained herein, or the rotation of the framework or end plates, as described below. The rotation of the port plates


219


or of the framework or end plates (as described below) can be accomplished in any one of a number of known mechanical ways known in the art.




In yet another embodiment of the invention, the framework, which in the embodiment shown would include the end plates, along with the port plates


219


therein, could be rotated and the block maintained as stationary.





FIG. 3

is a front schematic elevation view of embodiments of a rear end plate


110


and the front end plate


111


which may be utilized in the embodiment of this invention illustrated in FIG.


2


. In one embodiment, spacer dowels


280


are used to fix the relative positions of the front end plate


111


and the rear end plate


110


and bolts


281


are utilized to attach the end plates to the spacer dowels. It will be appreciated by those of ordinary skill in the art that there are other ways to space and retain the end plates within the contemplation of this invention, such as by framework supports behind the end plates or any one of a number of other ways, although the spacing dowels are preferred at this time.

FIG. 3

further illustrates central axis


117


around which the cylinder sets and the drive shaft would rotate.





FIG. 4

is a first end view from the front of front end plate


111


, illustrating front end plate


111


, three intake ports


285


and three exhaust ports


286


.

FIG. 4

further illustrates front bearing mount aperture


287


configured to receive a front bearing mount transfer ports rotate about the central axis, as shown in later figures.





FIG. 5

is a second end view of rear end plate


110


illustrating three intake ports


288


and three exhaust ports


289


, along with drive shaft mount aperture


290


. In the embodiment shown and described, the rear end plate ports are out of phase with the front end plate ports by approximately thirty (30) degrees counterclockwise, looking from the front. Arranging the rear end ports out of phase with the front end plate ports allows for cylinder firing to occur at even intervals as the double-sided piston reciprocates in its bores, creating the four cycles of intake, compression, combustion and exhaust. The combustion is initiated by the spark plug with timing similar to standard reciprocating engines which are generally known.




In looking back at

FIG. 4

, there may be three firing cycles per cylinder set revolution, where the cylinder set is the cylinders, the pistons and their mounting assembly. By way of example, it would take approximately six revolutions of the crank shaft to produce one revolution of a cylinder about the engine's centerline. That ratio and that one cylinder fires three times during that one revolution. Two turns of the crank set produces four combustion cycles, which may be the same as standard eight-cylinder engines.




As shown in

FIGS. 4 and 5

, exhaust ports and intake ports are arranged radially to communicate with the cylinder ports or transfer ports as the transfer ports are rotated about the central axis of the engine. The inlet and exhaust ports in the front end plate


111


are arranged in clockwise order with the exhaust port being first to communicate with the cylinder port in their respective groupings. In the layout shown in

FIGS. 4 and 5

, layouts of the end plates shown in

FIGS. 4 and 5

, the diagram is for an eight-cylinder version of the engine, which is contemplated by embodiments of this invention. In the embodiments in which only four cylinders are utilized, it will produce half as many combustion cycles.




The end plates shown in

FIGS. 3

,


4


and


5


also may function as framing members and mounting fixtures for port plates, intake and exhaust systems and as cooling towers for the engine coolant. Coolant passages may be machined or cast into the interior of the end plates surrounding all the attached entities.





FIGS. 6 through 11

show the rotation schematic end view of the rear end plate


110


as the cylinder sets rotate about the center axis of the engine, at approximately 60-degree intervals.





FIG. 6

, for example, would be the theoretical starting point or 0 degrees location of the cylinder set relative to the rear end plate


110


. First cylinder


300


and second cylinder


301

FIG. 12

is a simplified end view schematic of a cylinder, such as a cylinder shown in

FIG. 14

, illustrating an exemplary cylinder


310


with transfer port


311


and terminal end


312


which would interact with an end plate. The cylinder shown in

FIG. 12

is an exemplary cylinder, simplified for purposes of illustration.





FIG. 13

321


in linear fashion such that the first piston head


322


and the second piston head


324


, along with the piston rods


323

327


in internal gear


326


in which circular base


328


is rotatably mounted or disposed. Crankpin


329


is eccentrically mounted on circular base


328


. The sequence of phantom lines shows the relative movement of crankpin


329


through the cycle, as well as the relative movement of circular base


328


, all while maintaining a substantially linear movement along axis


330


of the piston rods and piston heads.

357


are also illustrated with first transfer port


358


and second transfer port


359


also being shown. Head bolts


360


are shown as one way of attaching the components of the cylinder together.

that the first cylinder face


380


and the second cylinder face


381


are contoured to generally or substantially match the shape of terminal end


351


of cylinder


350


. The matching as shown with a portion of the piston face protruding into or toward the transfer port


358


provides a more efficient configuration and better “squish” as known by those of ordinary skill in the art. While not required to practice this invention the contoured shape of the piston face and the terminal end of the cylinder are contoured and smooth, configured to efficiently allow the flow of gases and product of combustion, whereas in typical cylinders the cylinders are shaped to accommodate and/or control other aspects of the engine, such as better control of the valves.

. Arrow


399


illustrates a direction that circular base


403


may rotate within circular base aperture


370


and crankpin axis


127


is an axis about which crankpin


398


rotates relative to the circular base


403


. Crankpin


398


concurrently moves about crankset axis


117


.




Crankpin


398


, which may also be referred to as a main shaft, drive pin or any one of a number of different names, is preferably integral or unitary with circular base


403


and rotates therewith. Crankpin gear


401


is fixed to and around crankpin


398


and has external teeth as shown which correspond to internal teeth on internal gear


400


to matingly interact. As circular base


403


rotates clockwise in the view shown, crankpin gear


401


rotates counterclockwise within internal gear


400


. The relative sizing of circular base


403


, the eccentric mounting relationship of crankpin


398


to circular base


403


, the size and configuration of crankpin gear


401


and the size and configuration of internal gear


400


all combine to offset one another in a transverse direction such that the overall movement of the piston set is linear, or reciprocating when it occurs within the cylinder set. The crankpin gear


401


, a smaller orbiting gear, is forced around its own axis in a counterclockwise direction, thereby forcing the orbit in a clockwise direction within internal gear


400


, which in turn forces the crankpin


398


and the circular base


403


to rotate clockwise. It will be appreciated by those of ordinary skill in the art that it is not necessary to utilize a circular base in a circular base aperture, but instead the crankpin


398


may otherwise be eccentrically mounted relative to the piston set to rotate about a crankpin axis and about a crankset axis.





FIG. 18

is an illustration of an internal gear


400


, a crankpin gear


401


and a direction of rotation arrow


407


showing a counterclockwise rotation of crankpin gear


401


about its own axis, which allows the depiction of crankpin gear


401


's clockwise orbit within internal gear


400


. The center of internal gear


400


may also be the center of rotation of the crankset, also referred to as the crank set axis


117


, which is transverse to the central axis


115


of the engine, which is shown in FIG.


2


.




The internal gear


400


is preferably stationary and crankpin gear


401


generally rotates at a ratio of approximately 2 to 1 for each orbit within internal gear


400


. It can also be seen that crankpin


402


is eccentrically mounted relative to the piston set, by mounting it on circular base


403


(as shown in FIGS.


17


and


18


).





FIG. 19

is another schematic depiction of a piston set interacting with internal gear


400


, the piston set being numbered


362


, similar to that shown in

FIG. 17

, only showing various positions of the crankpin


402


by the phantom lines, as it moves with crankpin gear


401


clockwise within internal gear


400


. The phantom lines illustrate the first crankpin position


402

approximately 90 degrees from the original position of crankpin


402


. Crankpin

FIG. 20

is a cross sectional view of a crank set layout which may be utilized in an embodiment of this invention.

FIG. 20

illustrates central axis


115


of the engine with drive shaft


116


being generally centered about central axis


115


. Drive shaft bearings


174


locate and position drive shaft


116


relative to central axis


115


and other components of the engine, pump or compressor. Internal gear


162


and crankpin gear


163


on the upper crank set side are shown, as depicted and explained in more detail in prior figures. Circular base


160


and crankpin


161


are integral or unitary with circular base


160


. Not shown is circular base aperture which circular base


160


would generally be rotatably mounted within and driven by. First outer crank module


165


has crankpin


161


eccentrically and rotatably mounted within it and as the piston set forces circular base


160


and crankpin


161


to rotate, this likewise forces first outer crank module


165


to rotate and drive an outer gear mounted thereto in the direction of the arrow shown. The first outer crank module


165


generally and approximately rotates about crank axis


117


, which is generally transverse and perpendicular to central axis


115


. First outer crank module


165


utilizes bearing


248


to locate and allow rotation thereof.




The opposing or opposite side of crankpin


161


is eccentrically mounted within first inner crank module


167


such that crankpin


161


may rotate within the aperture in which it is received. Forcing the rotation of circular base


160


and crankpin


161


likewise forces the rotation of first inner crank module


167


about crank set axis


117


.




It can be seen that first inner crank module


167


interacts with drive shaft gearing


172


to cause rotation of drive shaft


116


. The rotation transfer mechanism may be any one of a number of different types of gears or means, all of which are generally known in the field of art.




There is a stabilizing mini shaft


170


fixed to first inner crank module


167


to provide additional stability and location of the rotation, and is generally centered about crank set axis


117


. The stabilizing mini shaft


170


is supported and located by pin bearings as shown.




At the lower end of

FIG. 20

is the same general configuration as the upper end, illustrating second outer crank module


222


mounted within bearing


246


. Crankpin


213


is eccentrically mounted on circular base


212


and rotatably and eccentrically mounted within second outer crank module


222


and eccentrically and rotatably mounted within second inner crank module


221


, as shown. Second inner crank module


221


includes second inner crank module gear


250


which interacts with drive shaft gear


172


to provide drive rotation to drive shaft


116


. Stabilizing stub shaft


224


is mounted within pin bearings as shown and has similar location and function to stabilizing mini shaft


170


on the upper portion of the crank set as shown.





FIG. 20

also shows second inner crank module bearing


222


and internal gear


220


. First inner crank module gear


171


will generally correspond to second inner crank module gear


250


in configuration and interaction with drive shaft gear


172


. It will be noted that the eccentrically mounted crankpins


161


and


213


are preferably one piece with circular base


160


and


212


respectfully.




Again, the inner and outer crank modules rotate about the crank axis


117


, forcing the circular bases


160


and


212


with eccentrically mounted crankpins


161


and


213


to counter rotate. In general, this embodiment of the invention requires a set of inner and outer crank modules, internal gear set and eccentrically mounted crankpins for each piston set. This engine design has flexibility in that it may easily and equally have a similar set of cylinder sets and crank sets at a ninety degree (90°) angle rotating about central axis


115


to increase the number of cylinders from 4 to 8 in a given application.





FIG. 21

is an exploded view of the crank set layout for this embodiment of the invention, illustrating first outer crank module


165


, circular base

, first inner crank module gear


171


, stabilizing mini-shaft


170


for first inner crank module


167


, drive shaft


116


with drive shaft gear


172


, second outer crank module


222


mounted and positioned within bearing


246


, second circular base

.

FIG. 21

further shows internal gear


220


, second inner crank module


221


with second inner crank module gear


250


thereon, and stabilizing stub shaft


224


. The crank set rotates about the crank set axis


117


.




First inner crank module gear


171


is preferably a 45-degree beveled gear, sized to accommodate for crank sets about the main drive shaft gear


172


. Second inner crank module gear


250


would preferably be the same or approximately the same as first inner crank module gear


171


and interact with drive shaft gear


172


in a similar fashion.





FIG. 22

is an end elevation view of a face plate


209


with first face plate aperture

a


and second face plate aperture


209




b


with central aperture


209




c


. The bores


209




a


and


209




b


generally go around the cylinder neck which then rotates face plate


209


with the cylinders. The face plate is preferably spring loaded to help seal the intake and exhaust ports when the ports are not communicating with transfer ports in the respective cylinder sets. The face plate surface that is sliding on the port plate would preferably be highly polished and lubricated depending on the specific application and materials used. Again, the face plate rotates with the cylinders and the seals and ports are cut out on the port plate which is immovably mounted on the end plate. The face plate is preferably equipped with an oil supply and scrapers for excess oil for sealing and lubrication purposes.





FIG. 23

is a front elevation view of face plate


209


. While the face plate shown is the preferred way to achieve lubrication and interaction of surfaces and ports at the time of filing, this may be done in any one of a number of different ways at the rear end plate, front end plate, or otherwise, all within the contemplation of this invention.





FIG. 24

is an end elevation view of the ring gear which is generally situated about the rotating perimeter of the engine, also shown in

FIG. 2

as item


245


. The ring gear has gearing on one or both sides and outer crank module gears


166


and


223


, as also shown in

FIG. 2

, interact with ring gear


245


to drive part or all of the rotation of the engine about its central axis. The interaction of the outer crank module gears


166


and


223


provides a driving force to rotate the cylinder set and piston sets around the central axis of the engine at a gear ratio of approximately 1 to 6, which would be the final output shaft of the engine or drive shaft. The approximate center of ring gear


245


will also be the approximate central axis of the engine. It will also be appreciated that the ring gear is stationary and does not rotate with the engine, but instead the two outer crank module gears


166


and


223


force the rotation of the engine through interaction with ring gear


245


. The ring gear is also provided with bolt holes for locating and fastening the ring gear to an outer housing.




It is preferable in a four-cylinder embodiment of this invention that there be two outer crank module gears


166


and


223


mounted 180 degrees apart. However, in the eight-cylinder embodiment of this invention, there would be four such outer crank module gears, each preferably and sequentially mounted 90 degrees apart from one another. The two outer crank module gears


166


and


223


generally rotate in opposite directions from one another, thereby forcing the cylinder set to rotate about the central axis of the engine.





FIG. 25

245


and first outer crank module gear

and second outer crank module gear

and fourth cylinder bore


411


would be utilized in an eight-cylinder embodiment of this invention. It should also be noted that cylinder block


400


would rotate about the central axis of the engine. Additionally, in the eight-cylinder version and in the preferred universal cylinder block, transverse crank set bores would be provided for the additional two cylinders, for example transverse crank set bore


412


would be similar in nature to crank set bores


405


and


406


.





FIG. 27

further illustrates shoulders

FIG. 37

is a perspective view of an embodiment of a gear cluster which may be utilized by this invention, showing an eight cylinder embodiment of an engine, pump or compressor gear cluster. The gear cluster


600


is shown with inner crank modules


601


,


603


,


605


and


606


, each having gears


609


,


610


,


607


and


608


respectively thereon. The inner crank modules have eccentrically positioned apertures


602


and


604


(with the apertures not shown for inner crank module


605


and


606


), and drive shaft


611


. The preferred ratio of rotation for the inner crank modules versus the drive shaft


611


are six-to-five (6:5). It should be noted it is preferred that the ratio be greater than one for relative sizing and interaction, although no one particular ratio is required to practice this invention.





FIG. 38

is a cross-sectional view of another embodiment of an engine contemplated by this invention, in which the rotation of the engine is via external gearing as shown.

FIG. 38

is the same as

FIG. 2

in many respects and each like component will therefore not be separately identified and described relative to FIG.


38


. However,

FIG. 38

does further illustrate an engine rotation system which utilizes a rotation gear


701


or sprocket mounted on or to a rotation gear shaft


702


, the rotation gear shaft


702


being rotatably mounted to the end-plates in this embodiment. The rotation gear


701


may be a gear, sprocket for receiving a chain, or any other mechanical configuration for transferring/receiving rotation from the drive shaft, all within the contemplation of this invention.




Although the rotation gear


701


is shown operatively attached or rotatably coupled to drive shaft gear


703


via chain


704


, it may be operatively or rotatably attached in any one of a number of different ways within the contemplation of this invention. The rotation of the drive shaft and consequently the drive shaft gear


703


, causes the rotation gear


701


and the rotation gear shaft


702


to rotate, which in turn rotates block drive gears


705


. Block drive gears


705


are operatively attached to and drive block gears


706


and the rotation of the block drive gears


705


thereby rotates the engine block, cylinder sets, etc. about the drive shaft axis. It is preferable that the gear or sprocket ratio between drive shaft gear


703


and rotation gear be a six-to-one (6:1) ratio in the embodiment shown. In this embodiment, this results in the block and cylinder sets rotating once about the central axis for every six rotations of the driveshaft. It should also be noted that in this embodiment, the outer crank gear and the ring gear as shown and described relative to

FIG. 2

has been replaced with the configuration shown.





FIG. 39

is a cross-sectional view of another embodiment of an engine contemplated by this invention, in which the rotation of the engine is via external gearing as shown.

FIG. 39

is the same as and/or similar to FIG.


2


and

FIG. 38

in many respects and each like component will therefore not be separately identified and described relative to FIG.


2


and/or FIG.


38


.

FIG. 39

, like

FIG. 38

, does further illustrate an engine rotation system which utilizes a rotation gear


701


or sprocket mounted on or to a rotation gear shaft


702


, the rotation gear shaft


702


being rotatably mounted to the end-plates in this embodiment.





FIG. 39

illustrates an embodiment of this invention which utilizes an additional gear in the gear cluster, a cluster rotation gear


712


, and a differential in the rotation of cluster rotation gear


712


, a block rotation gear, versus the rotation of the drive shaft, at a preferred 6:5 ratio, to achieve the rotation of the block. The configuration in

FIG. 39

is an embodiment showing another way to rotate the engine block, illustrating second rotation gear


708


or sprocket, is operatively connected to cluster rotation gear shaft


710


via gear or sprocket


709


, such that the cluster rotation gear shaft


710


and the cluster rotation gear


712


rotate in the opposite or reverse direction of rotation gear shaft


702


.




Mechanism


711


merely depicts any mechanism which may be used to reverse the rotation between the rotation gear shaft


702


and the cluster rotation gear shaft


710


. This mechanism may be by gearing or any other known means.




Also as stated above relative to

FIG. 2

, the relative rotation between the cylinders and the transfer ports in the cylinder relative to the intake and exhaust ports in the port plates and/or end plates is utilized as the valving function, and that may be accomplished within the contemplation of this invention by rotating the block and the cylinders, by rotating the port plates, or by rotating the framework or end plates, or some combination thereof.




As will be appreciated by those of reasonable skill in the art, there are numerous embodiments to this invention, and variations of elements and components which may be used, all within the scope of this invention.




For example, in one embodiment of the invention, a rotary engine, pump or compressor is provided which comprises: a stationary framework comprising a first port plate at a first side of the framework and a second port plate at a second side of the framework and fixed relative to the first port plate, each port plate comprising an intake port and an exhaust port through the port plate; a block rotatably mounted relative to the stationary framework and about a central axis; a first cylinder set and a second cylinder set mounted in the block in opposing relation from one another about the central axis, each cylinder set comprising: a first cylinder and an opposing second cylinder, each cylinder comprising a proximal end and a terminal end having a transfer port disposed to alternately form a passageway with the intake port and the exhaust port in the port plate; a first piston set movably mounted within the first cylinder set and a second piston set movably mounted within the second cylinder set, the first and second piston sets each comprising: a first piston in the first cylinder and a second piston in the second cylinder, each piston comprising a piston head with a piston face and a piston rod having a first end mounted to the piston head, wherein the piston rods are operatively attached to one another; a first crankset driven by the first piston set and a second crankset driven by the second piston set, the first crankset and the second crankset each comprising: a crankpin eccentrically mounted to the piston set to rotate about a crankpin axis; a crankpin gear fixed to the crankpin; an internal gear fixed relative to the first cylinder set, the internal gear having an internal gear configured to mate with the crankpin gear as the crankpin gear rotates within the internal gear; wherein the eccentric rotation of the crankpin offsets the rotation of the crankpin gear within the internal gear to provide approximately linear movement of the piston heads within the first and second cylinders and such that the crankpin also rotates about a crankset axis; an inward side of the crankpin being eccentrically mounted to an inner crank gear, such that the rotation of the crankpin also rotates the inner crank gear about the crankset axis; wherein the generally linear movement of the circular base aperture of the piston set drives the crankpin gear to rotate around within the internal gear, thereby driving the crankpin to rotate about the crankpin axis; and the inner crank gear mating with a driveshaft gear such that the rotation of the inner crank gear rotates the driveshaft.




In further embodiments to that disclosed in the preceding paragraph, a rotary engine, pump or compressor is provided, which further comprises a rotation gear rotatably mounted relative to the stationary framework and operatively attached to and driven by the driveshaft, and further wherein the rotation gear is disposed to drive the rotation of the block. In other further aspects of the invention to the preceding: a block drive gear is provided and driven by the rotation gear, the block drive gear operatively interacting with the block to drive the rotation of the block; or the block drive gear may operatively interact with the block to drive the rotation of the block via a block gear integral with the block and which corresponds to and is driven by the block drive gear; and still further, the rotation gear and the block drive gear may be integral.




While there are multiple possible ratios of rotation between the rotation gear and the driveshaft, an embodiment of the invention utilizes a rotation ratio of six-to-five.
