A rotary shaft carries a generally cylindrical composite rotor consisting of an inner cylindrical hub surrounded by a resilient undulatory spring sleeve which in turn is surrounded by a resilient cylindrical spring sleeve. Between the rotor and the internally cylindrical housing is an annular working chamber subdivided into compression and combustion chambers within which multiple cylindrical pistons of slightly greater diameter than the radial distance between the housing and rotor are snugly but orbitally rollable. Tangentially slidable in wedge-shaped recesses in the opposite end walls are upper piston-retarding wedges which are pushed backward into temporary braking engagement with the opposite ends of a leading piston immediately forward thereof in response to the pressure of the exploding gases in the combustion chamber which also propel forward to exhaust ports a piston ahead of the leading piston. Meanwhile a trailing piston behind the wedges, propelled by compressed intake gases, pushes the wedges forward and apart and moves past them. Each piston is also retarded against backward motion by a unidirectional spring-pressed braking clutch mounted in an axial bore therethrough. The compression chamber is supplied with fuel gas through an intake port located circumferentially beyond a lower piston-retarding device located beyond the exhaust ports near the end of the combustion chamber. Timing of the ignition is effected by a make-and-break device operated by one of the upper piston-retarding wedges in timed relationship with the orbiting pistons.
