ABSTRACT:
A capacity control circuit for a fluid displacement apparatus, especially for a rotary vane compressor, which circuit controls the volume of fluid displaced or transmitted through such apparatus. The present invention provides a means to retain the vanes within the rotor guide slits with a fluid pressure differential to modulate the volume throughput of such rotary vane compressor or apparatus. This vane control is provided by controlling the suction or input pressure to such apparatus through a fluid control valve.
