In a compressor provided with a suction throttle valve capable of reducing a low pressure pulsation by constricting a suction passage, a performance deterioration caused by an internal leakage of pressure guided to the suction throttle valve is decreased even when a suction control valve is configured by a spool valve. In a direction substantially perpendicular to an orientation of refrigerant flowing through a suction passage 36, a suction throttle valve 60 for adjusting a passage area of the suction passage 36 is provided, working fluid discharged to a discharge chamber 34 is guided to one end side of the suction throttle valve 60, the working fluid flowing in a suction chamber 33 is guided to the other end side of the suction throttle valve 60, and at the same time, a spring 63 for biasing the suction throttle valve 60 toward the one end side is provided. The suction throttle valve 60 is configured by a small diameter portion 61a slidably housed in a small hole portion 62a formed in a housing and a large diameter portion 61b formed consecutively with the small hole portion 62a and slidably housed in a large hole portion 62b provided to cross the suction passage 36. |
