Abstract of Disclosure Disclosed herein is an engine having opposed cylinders with a guided rotary and reciprocating piston which telescopes over an output shaft and transmits rotary motion directly to the output shaft without the need for a crankshaft. Guided rotary movement of the piston is afforded by rollers rotatably supported on a radial pin on the cylindrical wall of the piston. The rollers travel in an elliptical type groove on the inside surface of the cylinder to impart rotary motion to the piston as a result of rectilinear motion of the piston caused by com- bustion of fuel in the working chambers on opposite sides of the piston. The engine can also be operated by an external source of pressurized gas or operated as a pump. The rotary motion is transmitted to-the output shaft by a rider block which has a square cross section and which is fixed to the output shaft and is complementary in shape to a square opening in the piston. The rider block is movable between end walls in the piston. Circular openings with cylindrical seals seal the output shaft to the piston.
