ABSTRACT:
A rotor containing plural circumferentially spaced radial cylinders revolves in a concentric stationary housing around a fixed but adjustable profiled cam engaged by follower rollers on the connecting rods of pistons which reciprocate in the cylinders due to cam action during rotor rotation. A biasing spring for each piston maintains contact between the profiled cam and piston follower rollers. A secondary spring cushioned cam enables smooth transition of the piston follower rollers from an abrupt drop-off point on the main cam to a rotor torque inducing face thereof at the explosion point for each cylinder. Four cycle piston engine operation is achieved without the massiveness of a conventional fixed block piston engine of comparable displacement. The engine can be fuel injected or carburetor operated. Extreme simplicity of construction is achieved.
