ABSTRACT:
For controlling a displacement depending on a pressure differential between a crank chamber (9) and a suction chamber (4), a compressor is provided with a bleed passage (46) establishing communication between the crank chamber and the suction chamber and with a bleed control mechanism which fully closes the bleed passage while the compressor is stopped. The bleed control mechanism may be a suction valve (15) which controls the opening of suction holes of a valve plate (2) synchronously with a compressing operation of the compressor.
