<P>PROBLEM TO BE SOLVED: To provide a capacity regulator of reciprocating compressor unit not lowering a processing amount of a compressor when not performing capacity regulation, and not needing damper of pulsating motion. <P>SOLUTION: The capacity regulator of reciprocating compressor includes a clearance piston 13 housed inside a clearance pocket 11, a liquid cylinder 23 in which a power piston 24 is housed, a piston rod 25 for coupling the clearance piston 13 and the power piston 24, an operating fluid unit 20 equipped with an operating liquid pump 21 for pressurizing the operating liquid, a communicating pathways 26, 27 making the liquid cylinder 23 and the operating liquid pump 21 communicate with each other, and a controller 29 for controlling a revolution speed of the operating liquid pump 21. Based on an output signal output from the controller 29, the clearance piston 13 is moved by applying the pressure of the operating liquid fed from the operating fluid unit 20 to the power piston 24, and the capacity of a regulating chamber 12 inside the clearance pocket 11 is regulated. <P>COPYRIGHT: (C)2010,JPO&INPIT |
