Abstract
A rotary fluid compressor of the sliding vane type having a housing containing a closed working chamber and a rotor eccentrically mounted in the chamber. A control member is rotatably mounted in the housing and provided with an elongated arcuate aperture in fluid contact with the working chamber and spanning at least one of the vanes to permit fluid to bypass the vanes and thereby change the compression volume in the chamber.
