Internal combustion four cycle rotary engine based on a rotary movement that can be used to make a compressor, a vacuum pump, a steam engine and a high pressure water motor

Abstract

What I believe is a totally new mechanical movement consisting of a main stationary cylinder into which there is a rotary cylinder thru which a certain number of vanes that are anchored at the center of the main cylinder slide in and out of it by means of wigglets because the internal rotary cylinder is off-center of the main cylinder. As the internal cylinder rotates the space between two adjacent vanes increase or decrease creating a vacuum on one side of the main cylinder and a compression on the other side.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to internal combustion engines that utilize gasoline, diesel fuel, propane, natural gas, or any other combustible liquid or gas to produce power. Also, the same rotary movement can be used for other mechanical applications.

[0003] 2. Description of Related Art

[0004] Some existing engines that utilize those liquids or gasses to produce power consist of pistons that by means of a crank shaft go up and down of cylinders, and other engines consist of a heart-shaped rotor that turns around inside a trochoidal chamber.

SUMMARY OF THE INVENTION

[0005] The present invention does not have pistons that go up and down nor a rotor that shakes inside a trochoidal chamber, both of which rob a good portion of the power produced by the fuel.

[0006] The present invention consist of a rotor that turns inside a master cylinder which is the main body of the engine and through the rotor there are some vanes that slide in and out of it because the rotor is located off-center of the master cylinder.

[0007] As a consequence any two of those adjoining vanes produce a cavity that increases and decreases as the rotor turns.

[0008] The accompanying drawings, which are incorporated in and constitute part of the specifications, illustrate several embodiments of the invention and together with the description, serve to explain the principles of the invention.

DETAIL DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] Reference will now be made in detail to the preferred embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation of the invention, not for limitation on the invention. In fact, it will be apparent to those skilled in the art that modifications and variations can be made to the present invention without departing from the scope or spirit thereof.

[0036] The present invention is concerned with an internal combustion engine that has much less moving parts than a conventional piston-cylinder engines. It does not have pistons, it does not have connecting rods, crank shaft, nor valve lifters, all of which produce vibration and consume a good portion of the fuel used. This invention consist of one one cylinder which is the main body of the engine, and inside that cylinder there is a hollow rotor that turns off-center of it. That rotor has some longitudinal round openings though which same number of vanes slide in and out of it, and since those vanes are anchored to the epicenter of the cylinder and extend to touch it, as the rotor turns any two of those contiguous vanes create a cavity between a rotor and the cylinder and such cavity expands and contracts as the rotor turns, therefor performing the four cycles of intake, compression, power, and exhaust as a common four cycle piston engine.

[0037] Accordingly, FIG. 1 shows a radial cross-section of the engine which shows the main cylinder 1 in which are longitudinal openings in which rotary valves turn, three for intake 5i and and three for exhaust 5e. The vanes are anchored at the center of the main cylinder by a longitudinal rod 6 and extend through the rotor 2 by means of two wigglets 4 until they touch the inside of the main cylinder 1. As the rotor turns clockwise, two of those vanes 3 in alternate order create a vacuum that will be filled with the vaporized fuel through the three valves 5i until maximum capacity and past that point the combustible will be compressed until it reaches the minimum capacity 11 and at that point the compressed gas will be ignited by one or more spark plugs 7 generating the power cycle until the two vanes reach the maximum capacity and past that point the burnt gasses will exhaust thru the tree exhaust valves 5e. In the main cylinder are several longitudinal holes 19 through wich a coolant should be circulated and the placement and size of those holes should be determined by trial and error base on production.

[0038] FIG. 2 shows the the same cross-section as in FIG. 1 after the rotor has turned 36 degrees clockwise to show the maximum capacity 3 and the alternate firing order of 1, 3, 5, 2, 4.

[0039] FIG. 3 shows a longitudinal cross-section of the main cylinder 1 and the off-center position of the rotor 2 inside the main cylinder 1. It also shows the location of the vanes anchor rod 6 at the epicenter of cylinder 1. The rotor 2 is sealed inside the cylinder by two rings 12 and supported in place by the main shaft 13 which, by means of a sprocket 15 will turn the six valves 5 that have attached sprockets 6 by means of a chain that will be illustrated later. The main shaft 13 is maintained in place by means of ball bearings 14 or roller bearings or any other type of bearings to be lubricated in any conventional way.

[0040] FIG. 4 Shows several round holes 17 through the valves that permit the intake of combustible gasses in the intake cycle and and allow the gassed produced by combustion to exit the cylinder in the exhaust cycle. It also illustrates the sprockets 16 that will make the valves rotate.

[0041] FIG. 5 is a longitudinal cross-section of a valve to show the way to cool them by means of a passage 18 above and below the holes 17.

[0042] FIG. 6 is an end view of a vane that show the lateral seal 8 against both ends of the inside of the rotor and the seals 9 at the top of the vanes against the round portion of the rotor. The vanes are anchored at the epicenter of the cylinder by means of rings 19

[0043] FIG. 7 is a lateral view of a vane 3 to which three rings 19 are attached to be anchored at the epicenter of the main cylinder.

[0044] FIGS. 8 and 9 show only a portion of the vanes 3 with the position of the rings 19 attached to them so two of each could be flipped over. With one vane as in FIG. 7, two as in FIG. 8 and two as in FIG. 9, all the fifteen anchor rings 19 will interlock around a central pin to make it a five vanes rotary engine.

[0045] FIG. 10 is an open end perspective view of the engine showing showing the main cylinder 1 which is the core of the engine, the rotor 2 which will be made to turn by the vanes 3 and the wigglets 4 that permit the vanes to slide in and out through the rotor 2 and the valves 5 that rotate to either open to permit the fuel in or exhaust gasses out or close to compress the fuel until it is ignited and cause the power stroke. The intake openings 6 are for the fuel to get into the cylinder. The fuel should be channeled to these openings in any conventional way. The exhaust openings 7 are for the combustion gasses to get out. The exhaust gasses should be channeled out in any conventional way.

[0046] FIG. 11 is the flat side of the wigglets 4 showing where the lubricating fluid gets in 20 and tiny grooves 21 to let the lubricating oil to seep thru.

[0047] FIG. 12 is the round side of the wigglets 4 to show where the lubricating oil enters to seep thru 20 to seep thru tiny grooves 21.

[0048] FIG. 13 is the anchor rod 6 of the vanes to show where the lubricating oil enters through the it (22) and comes out of transverse holes 23 to lubricate the anchor rings.

[0049] FIG. 14 is a longitudinal cross-section of the anchor rod 6 mainly to show a ring 2 to provide a tight seal against the flat end of the rotating cylinder.

[0050] FIG. 15 is a cross-section of the master cylinder when a valve is fully open.

[0051] FIG. 16 shows the rotation of the valves as they open and close. On position 1 the valve is closed and will begin to open. As it rotates to position 2 it will have rotated 45 degrees and will be totally open. As it rotates to position 3 it will have rotated 90 degrees and the close cycle begins. When it reaches position 4 will have rotated 135 degrees and is in the closed cycle. When it has rotated 180 degrees will be back to position 1.

[0052] FIG. 17 shows two engines put together in tandem. Two cylinders 1, two rotors 2, two center anchors 3, two spark plugs 5, only one drive shaft 4, twice the number of vanes (not shown) only one driving sprocket 6, same number of valves and sprockets 7 and only one extra bearing 8.

[0053] FIG. 18 is a valve 7 for two engines in tandem to provide intake or exhaust for both. The openings 1 are serving one engine and the openings 2 are serving the other engine and are perpendicular to openings 1.

[0054] FIG. 19 show the rotating mechanism to make the valves open and close. The sprocket a is attached to the main shaft and move a chain b which engages sprockets c that are attached to the valves to make them rotate. Said chain goes through idle sprocket d that is attached to sliding plate e and secured in place with bolt f when the proper tension of the chain is obtained. The turn ratio of sprocket a to sprockets b is as follows: when sprocket a turns 72 degrees sprockets c turn 90 degrees. To accomplish this, assuming this is a 5-vanes motor, sprocket a has 15 teeth and sprockets c have 12 teeth.

[0055] FIG. 20 is a vacuum pump based on the same principle of the internal combustion engine because the movement is the same but it does not have any valves. It consist of a main cylinder A inside which there is a rotating cylinder B through which a multiple number of vanes C anchored at D which is at the epicenter of A slide in and out through wigglets E and in doing as the rotor moves clockwise a vacuum is created between inside cylinder A and outside of rotor B and when the vanes reach a point where one-way valve H is located air is sucked-in creating a vacuum at point I. The air sucked-in is expelled through radial openings on the main cylinder from point F to point G

[0056] FIG. 21 shows the radial openings B on the main cylinder A from point F to point G and the shaft E where power is applied to rotate the inner rotor and produce the vacuum.

[0057] FIG. 22 is a steam engine consisting in a main cylinder A into which several vanes B that are anchored at the center point D and slide in and out of a rotor E through wigglets C to touch the inside of cylinder A. On one side of the cylinder is a shroud that carries the steam through radial openings on the main cylinder and the steam will hit the vanes and will make the rotor E move forward clockwise. On the other side of the engine there is another shroud G over the radial openings to let escape the unused steam and water at collecting point I.

[0058] FIG. 23 is a side view of the engine without the shroud to show the radial openings B from point C to point D and the shaft to harness the power produced by the steam.

[0059] FIG. 24 is a cross-section of a power generating dam where A is the dam, B is the water reservoir created by the dam, C is the turbine moved by the high pressure of the water and D is the vertical shaft that connects the turbine with the generator E to produce power and F is the used water discharged to the river.

[0060] FIG. 25 is a high pressure water motor consisting in an outer cylinder A and inside it are several vanes B anchored at the center D and sliding through rotor E by means of wigglets C and extending until they touch the inside or cylinder A On the right side of the illustrated cylinder there are some radial openings that permit the high pressure water to enter cylinder A and hitting the vanes that will force the rotor E to move clockwise to produce power. On the left side of the illustration there are also radial openings that discharge the used water to the river.

[0061] FIG. 26 is a side view of main cylinder A to show the radial openings B from point D to point E and the power shaft to be used to turn the power generator on top of the dam.

[0062] FIG. 27 is a compressor without pistons or diaphragms and only one one-way valve. It consists of a cylinder A and inside it are several vanes C anchored at a center point D and sliding through rotor B through wigglets E and touching the inner side of the rotor. There are some radials openings on cylinder A from point F to point G. As power is applied to make the rotor move clockwise, air will be sucked through the radial openings and when the vanes reach point G the compression cycle will begin and the compressed air will exit through one-way valve H to a holding tank or to any system requiring compressed air.

[0063] FIG. 28 show the right side of cylinder A to see the radial openings B that go from point C to point D and the shaft E where power is connected to move the inside rotor.

Claims

1- A rotary internal combustion engine that consist of a cylinder in which an odd number of vanes slide in and out of an internal rotor by means of wigglets that permit the vanes to slide in and out of the rotor at different angles and cause cavities that increase and decrease as a piston engine does. The intake of combustible gasses and the exhaust of gasses produced by combustion will be by means of rotary longitudinal valves. The ignition of the combustible will be by means of one or more spark plugs.

2- A steam engine consisting of a cylinder into which a multiple number of vanes slide in and out of an internal rotor by means of wigglets that permit the vanes to slide through the rotor at different angles creating cavities into which the high pressure steam will enter to push the vanes that will turn the internal rotor and therefor producing power. There are no valves of any kind. The steam will enter the main cylinder though radial openings on one side and the spent steam and water will exit the main cylinder through the radial openings on the other side.

3- A high pressure water motor exactly the same as the steam engine to be used in power dams using the high pressure water at the bottom of the reservoir to enter the cylinder thru radial openings on one side and discharge the water to the river thru radial openings on the other side.

4- An air or gas compressor with the same rotary mechanism described above. The air or gas will enter the main cylinder thru radial openings on one side and as power is applied to the internal rotor the vanes will compress the air or gas on the other side of the cylinder and at the point of maximum compression will exit the cylinder thru a one-way valve and from that point to a holding tank or any other devise.

5- A vacuum pump which is quite the opposite of the compressor. As the rotor is made to turn, the expanding cavities created by two contiguous vanes create a vacuum and when that cavity reaches the maximum point, air or gas will be sucked in thru a one-way valve and will be discharged thru radial openings to the air or, by not having radial openings for discharge, the air or gas that was sucked in will be compressed and at the point of maximum compression will exit the cylinder thru a one-way valve, creating a dual purpose pump.
