A rotary engine employs one or more flap-type pistons which swing about a fixed pivot. Power is transmitted from the pistons to the output shaft by pins connected to the piston which ride in figure eight grooves in a pair of spaced discs connected to the output shaft. The discs are spring-loaded toward each other to provide side seals along the sides of the pistons. Ports in the discs register with a working chamber in the appropriate sequence for the intake and exhaust strokes. Hence conventional valving is not required.
