摘要：
A vane type compressor includes a plurality of working chambers defined by the cooperation of a rotor, a plurality of vanes and a cam ring. A valve assembly is disposed in a low pressure passage communicated with the working chambers and operative to bring a portion of the low pressure passage communicated with at least one of the working chambers to a full-closed or full-open position, to thereby effect control of the volume of gas discharged from the compressor.
