ABSTRACT:
A sliding-vane rotary compressor cylinder having a row of discharge holes arranged in an axial direction of the cylinder, and a corresponding number of discharge valves normally closing the respective discharge holes. The opening of two endmost discharge valves is limited by a first valve-opening limiting device to a first value. The opening of the remaining discharge valves is limited by a second valve-opening limiting device to a predetermined value which is larger than the first value. With this construction, the a rotor rotatably received in the cylinder is stably held in position against axial displacement or oscillation.
