<p><P>PROBLEM TO BE SOLVED: To provide a compressor for surely preventing vibration and noise by self-excited vibration of a suction valve in low flow rate. <P>SOLUTION: This compressor has bypass passages 16 and 17 for communicating a refrigerant suction passage 13d with a refrigerant delivery passage 13c and a bypass valve 40 for opening-closing the bypass passages 16 and 17, and makes a partial refrigerant of the refrigerant delivery passage 13c flow in a cylinder 11a by communicating the bypass passages 16 and 17 by the bypass valve 40 at low flow rate time. Thus, a flow rate of the refrigerant sucked in the cylinder 11a is not reduced more than necessary even at low flow rate time, and the suction valve 14c can be always operated up to opening for contacting with a stopper 11b to surely prevent generation of the vibration and the noise by the self-excited vibration of the suction valve 14c at low flow rate time. <P>COPYRIGHT: (C)2004,JPO</p> |
