Abstract

A compound supercharged rotary piston engine device in which a rotary piston compressor is interposed between a pair of rotary piston engines to form a unit. A single shaft extends through the unit and has coaxial eccentrics for the engines and an eccentric displaced 180.degree. therefrom for the compressor. The compressor supplies primary combustion air to the engines and also supplies air thereto for afterburning uncombusted fuel entrained in the exhaust gases of the engines. The air supply from the compressor to the engines takes place in a set of passages in the walls which separate the compressor from the engines and the passages are under the control of the pistons of the device.
