Patent ID: 7757658

Claim:
A rotary internal combustion engine comprising: a housing means defining a combustion chamber having a polygonal shaped inner surface and ends and a central axis passing there-through, a driveshaft means rotationally mounted in the housing means, a polygonal shaped rotor including surfaces and positioned off-center of the central chamber axis, a plurality of vanes disposed about said rotor creating at least three sections of said combustion chamber within the engine, wherein each of said surfaces of said polygonal shaped rotor are in contact with each of said three sections of said combustion chamber, and wherein said polygonal shaped rotor operates in four Otto cycles relative to each of said at least three sections of said combustion chamber, an eccentric member secured to said driveshaft means for converting orbit motion of said rotor into shaft rotational energy, vane pins positioned around a peripheral of said polygonal shaped rotor and allowing said vanes to be in slidable contact with the polygonal shaped rotor, vane channels disposed about the inner surface of the ends of the housing means to restrict the movement of said vanes, vane recesses disposed about the inner surface of the housing means allow said vanes to move in and out of the housing means, means for providing a combustible air and fuel mixture to each of said at least three sections of said combustion chamber, at least one set of intake and exhaust valve means, wherein said at least one set of intake and exhaust valve means is positioned in communication with each of said at least three sections of said combustion chamber mounted on the housing means for controlling the flow of said air and fuel mixture into and out of said at least three sections of said combustion chamber, wherein said vanes are located between said at least one set of said intake and exhaust valve means in said combustion chamber, means for operating said at least one set of said intake and exhaust valve means in timed relation with the orbit motion of said polygonal shaped rotor to allow said air and fuel mixture to flow into each of said at least three sections of said combustion chamber and allow exhaust gases to flow out of each of said at least three sections of said combustion chamber, and a fuel ignition means in communication with each of said at least three sections of said combustion chamber operable to ignite the fuel in said combustion chamber to thereby cause said rotor to have orbital movement and rotate the driveshaft means.
