<P>PROBLEM TO BE SOLVED: To prevent performance deterioration caused by internal leakage of pressure guided to a suction throttle valve, even when a suction control valve is constituted of a spool valve, in a compressor including the suction throttle valve capable of reducing low pressure pulsation by throttling a suction passage. <P>SOLUTION: The suction throttle valve 60 for adjusting the area of the suction passage 36 is provided in a direction substantially orthogonal to the direction of coolant flowing in the suction passage 36. Working fluid discharged to a discharge chamber 34 is guided to one end side of the suction throttle valve 60. Working fluid flowing in a suction chamber 33 is guided to the other end side of the suction throttle valve 60. A spring 63 is provided to bias the suction throttle valve 60 toward the one end side. The suction throttle valve 60 comprises: 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 part 62a and slidably housed in a large hole portion 62b provided to cross the suction passage 36. <P>COPYRIGHT: (C)2012,JPO&INPIT |
