Abstract

A rotary vane-type engine includes a rotor, a cam ring surrounding the rotor, and working vanes slidably disposed in radial slots of the rotor and engaging with one of their ends the inner contour of the cam ring. The vanes subdivide the space formed between the rotor and the cam ring into working spaces which are limited axially by side plates. Control ports provided in the side plates have throttle channels which extend in the rotor circumferential direction and connect the working spaces arranged on either side of the throttle channel with each other.
