ABSTRACT:
A rotating cylinder engine having a stationary housing surrounding a rotating cylinder block which rotates unitarily but eccentrically with an output shaft. The housing rotatably mounting both the shaft and the cylinder block. The output shaft has cam flats cooperatively positioned with cylinders in the cylinder block; the cylinders having sealed outer ends. A piston is slideable in each cylinder with its inner end sealingly and slidingly engaging an associated cam flat. Fluid passages in said cam flats alternate from a source of pressured air and from an exhaust. The pistons have a central bore therein confluent with the fluid passages in the cam flats so that pressure can flow through the piston and react between the outer ends of the cylinders and the cam flats, and the cylinder block and the cam flats rotate unitarily but eccentrically. In one embodiment, bridle rings hold the pistons on the cam flats. In another embodiment, springs react between the closed cylinder ends and the outer ends of the pistons to hold the pistons on the cam flats.
