摘要： A rotational engine system comprises a rotational engine and a propulsion system. The rotational engine includes an outer ring enclosure, an inner ring component, and a drive gear. The inner ring component includes a piston and a drive gear engagement portion. The piston is configured to travel within the outer ring enclosure along a circumference of the outer ring enclosure. The drive gear engagement portion is configured to rotate as the piston travels along the circumference of the circular shape of the outer ring enclosure. The drive gear is coupled to the drive gear engagement portion of the inner ring component such that rotation of the drive gear engagement portion rotationally drives the drive gear. The propulsion system is configured to deliver propulsive energy to propel the piston along the circumference of the outer ring enclosure.

摘要： The disclosure provides rotary machines that include, in one embodiment, a rotatable shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first hub that defines a first gearbox disposed thereon with a plurality pivots. At least one contour also having pivots is connected to the first gearbox pivots by two linkages exterior to the first gearbox. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume. A gearbox mechanism including gears, crankshafts, bearings and connecting rods creates an oscillatory motion 2 times per revolution in the linkages such that the contour is forced to navigate about the arcuate cavity without contacting the cavity at a high rate of rotating speed.

摘要： A rotary roller motor is disclosed herein. The rotary roller motor is a four-stroke internal combustion engine, wherein the rotor “rolls” around the inside of the engine block. The rotor is a two-part rotor having an inner part with a shaft and an offset circular lobe, and an outer rotor fit around the lobe. Two barriers are provided around the rotor chamber, a compression/power barrier and an exhaust/intake barrier. The combustion chamber has a non-reversing compression barrier and a compression hold barrier regulating the combustion of gas.

摘要： Each of recesses in outer circumferential surfaces of rotors includes: a leading-side area extending forward from a longitudinal center of an associated one of the outer circumferential surfaces in a rotation direction of the rotor, and a trailing-side area continuous with the leading-side area, and extending rearward from the longitudinal center in the rotation direction. From the longitudinal center of the associated one of the outer circumferential surfaces in the rotation direction, forward extension of the leading-side area is longer than rearward extension of the trailing-side area. The leading-side area has a larger volume than the trailing-side area.

摘要： A circle-ellipse engine includes a stationary circular outer housing having a fixed elliptical inner cam surface, and a separate internal round rotor partitioned into equal segments that are populated by identical movable radial vanes. During rotation, the end of the vanes are positioned a precise, constant distance from the elliptical inner cam surface of the housing. During rotation, a variable height cavity is created representing the difference between the major and minor axes of the elliptical inner cam surface and the rotor face. During each rotation, aspirated air is continuously drawn into combustion chambers, compressed, mixed with fuel, ignited, and exhaust gas products are expelled.
