Rotary internal combustion engine with cam transmission

An internal combustion engine comprising a substantially cylinderical casing having grooves therein, a multilobed rotor being rotatably mounted within said casing, a plurality of substantially cross-sectionally U-shaped combustion chambers slideably mounted in said grooves in said casing and projecting inwardly so that the innermost point or face of said chambers are adjacent with the outer face profile of said rotor, the outer profile of said rotor having a circumferential toothed formation thereon, each of said chambers rotatably supporting a gear wheel which is intended to engage and bear upon the toothed formation on the outer profile of said rotor, ignition means and fuel inlet means and exhaust means being provided within said casing for each of said U-shaped chambers, the central longitudinal axis of each combustion chamber being angularly displaced from the radial axis of said casing such that the innermost end of said combustion chamber is displaced in the direction of rotation of said rotor, said grooves being annular in shape and said U-shaped chambers are cylindrical in shape and are mounted in said grooves such as to permit axial movement of said chambers in said grooves.

An internal combustion engine comprising a substantially cylindrical casing having grooves therein, a polygonal rotor being mounted to move with an orbital motion within said casing, a plurality of substantially cross-sectionally U-shaped combustion chambers slidably mounted in said grooves in said casing and projecting inwardly so that the innermost point or face of said chambers are adjacent with the outer face profile of said rotor, ignition means and fuel inlet and exhaust means being provided within said casing for each of said U-shaped chambers, said rotor having slots therein, said chambers each having a pin slideably mounted in one of said rotor slots, said casing grooves being annular in shape, said U-shaped chambers being cylindrical in shape and being slideably mounted in said casing grooves for allowing radial movement of said chambers in said casing grooves.
