DETAIL DESCRIPTIONS OF THE INVENTION

All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

The present invention utilizes a cam 16 and follower system in a pursing piston engine, cat and mouse engine, rotary engine, or toroidal engine. A cam and follower system is used to control the relationship of a compression piston 3 in reference to a power piston 2. This relationship allows the compression piston 3 to be controlled for optimum distance control from the power piston 2 while the power piston 2 harvests the energy produced in a smooth and consistent manner. The present invention comprises a rotating power piston 2 in a ring chamber 1, a compression piston 3, a plurality of ring air inlets 11, a plurality of exhausts 12, a plurality of fuel introductions 13, a plurality of ignition sparks 14, a cam 16, and a plurality of slots 31 with two slots, a plurality of followers 17, an engine casting, and a connecting rod 32.

A constantly rotating power piston 2 in a ring chamber 1 is followed by a compression piston 3, stopping and restarting. By use of the cam 16 on the power shaft on the inner diameter of the engine, a plurality of followers 17 and connecting rod 32 adjusts the separation between the power piston 2 and compression piston 3. Proper location of the plurality of ring air inlets 11, the plurality of exhausts 12, the plurality of fuel introductions 13 and the plurality of ignition sparks 14 complete the engine.

In reference to FIG. 1-11, the present invention comprises a ring chamber 1, a power piston 2, and a compression piston 3. The ring chamber 1 comprises a plurality of ring air inlets 11, a plurality of exhausts 12, a plurality of fuel introductions 13, a plurality of ignition sparks 14, a cam 16, and a plurality of followers 17. The power piston 2 comprises a power ring 21 and a power rod. The compression piston 3 comprises a plurality of slots 31, a connecting rod 32, a compression arm 33, and a compression ring 34. The power piston 2 and compression piston 3 is fitted within the ring chamber 1. Accordingly, the power piston 2 and compression piston 3 create a sealed area within the ring chamber 1. The power piston 2 and compression piston 3 rotates in a circular motion around the connecting rod 32 wherein the power piston 2 is secured to the connecting rod 32. Consequently, the power piston 2 and compression piston 3 rotate in a circular manner. The power piston 2 mechanically couples to the compression piston 3 wherein the compression piston 3 is less mass than the power piston 2. As a result, the compression piston 3 follows the motion of the power piston 2, with a controlled distance between the two pistons. The compression piston 3 compresses a fuel mixture within the ring chamber 1. Thus, the fuel mixture is compressed to continue the engine firing process. The plurality of ignition sparks 14 ignites the compressed fuel mixture within the ring chamber 1. So, the compressed fuel mixture produces a rotating force with the power piston 2.

In reference to FIG. 3, the plurality of ring air inlets 11 feeds air into the ring chamber 1 in-between the power piston 2 and compression piston 3. Accordingly, air is fed into the ring chamber 1. The plurality of fuel introductions 13 feeds fuel into the ring chamber 1 in-between the power piston 2 and compression piston 3. Consequently, the fuel is introduced into the ring chamber 1 at the same position A when the air is introduced to the ring chamber 1. The air and fuel forms a fuel mixture within the ring chamber 1. As a result, the fuel mixture is optimized for the engine firing process. The plurality of ring air inlets 11 and plurality of fuel introductions 13 integrates along the outer circumference of the ring chamber 1. Thus, the air and fuel can be introduced into the ring chamber 1 and sealed off from the outer environment.

Further, the plurality of ignition sparks 14 ignites the fuel mixture within the ring chamber 1. So, the fuel mixture produces a force once ignited. The fuel mixture rotates the power piston 2. Accordingly, the power piston 2 is pushed along the ring chamber 1 into a new position B as seen in FIG. 9. The fuel mixture exits the ring chamber 1 at the plurality of exhausts 12. Consequently, the fuel mixture, after igniting and pushing the power piston 2 to position B, leaves the ring chamber 1 to allow for a new fuel mixture to enter the ring chamber 1, wherein the engine firing process repeats. The plurality of ignition sparks 14 and the plurality of exhausts 12 integrates along the outer circumference of the ring chamber 1. As a result, the fuel mixture can easily exit the ring chamber 1 and a spark can reach into and ignite a new fuel mixture.

In reference to FIG. 2, the cam 16 maintains proper distance between the power piston 2 and compression piston 3 throughout the engine firing. Thus, this design ensures the distance between the power piston 2 and the compression piston 3 is optimal throughout the engine firing process. The cam 16 further comprises a guide member 161. The guide member 161 provides a channel, slot, protrusion, ledge, ridge, or lip to control the vertical motion of a mechanically coupled piece.

Further, the plurality of followers 17 mechanically couples the power piston 2 and compression piston 3 to the cam 16. Accordingly, the power piston 2 and compression piston 3 motion are controlled by the cam 16. The plurality of followers 17 comprises a top end 171 and a bottom end 172. The top and bottom end 172 being cylindrical members that extend into the ring chamber 1 through the power piston 2 and compression piston 3. The top end 171 is pivotally pinned to the power piston 2 as seen in FIG. 8. In an alternative embodiment a dual slot is possible to receive the plurality of followers 17. Consequently, the plurality of followers 17 rotates around the pinned point along the power piston 2. The bottom end 172 is mechanically coupled to the cam 16. The bottom end 172 traverses through the guide member 161 configuration along the cam 16. As a result, the bottom end 172 moves the compression piston 3 along the guide member 161 of the cam 16 and maintains a proper distance between the power piston 2 and compression piston 3.

In reference to FIG. 1, the power ring 21 forms a circular shape that fits within the ring chamber 1. The power arm 22 connects one end of the power piston 2 to the other end. Thus, the power arm 22 ensures that the power pistons 2 are on opposite sides of the ring chamber 1. The power piston 2 and compression piston 3 can be designed with a round, square, triangular or other similar shape that would allow for compression of the fuel mixture.

Further, the compression ring 34 forms a circular shape that fits within the ring chamber 1 shown in FIG. 1. The compression arm 33 connects one end of the compression piston 3 to the other end. So, the compression arm 33 ensures that the compression pistons 3 are on opposite sides of the ring chamber 1. The power ring 21 receives the compression ring 34. Accordingly, the compression ring 34 is mechanically coupled to the power ring 21 and allows for each ring to rotate in place along the other ring. The motion of the compression piston 3 allows for pressure to exhaust, creates a vacuum for intake, and provides compression and a back stop for ignition.

Furthermore, the connecting rod 32 traverses through the compression arm 33 through the power arm 22. Consequently, the connecting rod 32 provides a pivot point for the compression arm 33 and power arm 22 to rotate around. The plurality of slots 31 integrates along the compression arm 33. The plurality of slots 31 is two linear slots positioned on either side of the connecting rod 32 as seen in FIG. 1. The plurality of followers 17 traverses through the plurality of slots 31. As a result, the plurality of followers 17 moves along the plurality of slots 31. The plurality of slots 31 constrains the movement of the plurality of followers 17.

Multiple power and compression pairs can be designed into the engine. These are the basics for the engine. The power piston 2 and compression piston 3 can be designed round or square or anything in-between. A basic design includes the power piston 2 and compression piston 3 for robustness. In an alternative embodiment, the cam 16 has a guide member 161 with different widths and depths that enables the plurality of followers 17 to have different paths on one cam 16. Within the preferred embodiment the plurality of followers 17 move along the guide member 161 controlling the distance between the power piston 2 and compression piston 3 for optimal performance. A second cam on the opposite side of the engine casting can be used for more robust adjustments of the connecting rod 32. The engine casting comprises a gear housing front 4, a gear housing rear 5 and a front cover 6. A lobe cam, slotless or a dual slot cam can be utilized by the present invention in an alternative embodiment as seen in FIG. 10 and FIG. 11. The lobe cam utilizes a cam 16 with a guiding member which is a ledge, lip, protrusion or ridge that guides the plurality of followers 17 around the cam 16. This design enables the present invention to control the distance between the power piston 2 and compression piston 3 for optimal performance without a slot. The slotless cam enables the following member 17 to move around the guide member 161 with the bottom end 172. The top end 171 is coupled to the power piston 2 via a hole within the power piston 2 and a middle end extends in the same direction as the top end 171 and bottom end 172. The middle end is coupled to the compression piston 3 but is not confined or linked to a slot or hole.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
