ABSTRACT:
A four-cycle rotary engine having a generally tubular cylindrical housing with end covers rotatably supporting an output shaft extending axially of the housing, an annular cylinder block assembly, secured to and surrounding the output shaft, has a plurality of cylinders extending axially parallel to the output shaft and a piston mounted in each cylinder. Each piston has a rod constrained to move parallel to the axis of the output shaft by guides formed on the cylinder block, and each rod has roller followers engaging opposed cam tracks of a stationary drive ring secured to the housing. The cam tracks are sinusoidal, are circularly concentric with the axis of the drive shaft, define the working strokes of the cylinders, and cause the cylinder assembly and the output shaft to rotate from the reaction between each rod and the cam tracks on the combustion stroke of each piston. Intake and exhaust ports in the head and cover of the housing automatically admit the fuel-air mixture and release the exhaust gases as the cylinder rotates.
