<P>PROBLEM TO BE SOLVED: To provide a compressor capable of reducing discharge pulsation and suppressing generation of vibration of the compressor itself also. <P>SOLUTION: The compressor includes a suction port 9 sucking coolant to a cylinder 1 and a cylinder head cover 12 having a first delivery space 12-2 for discharging compressed exhaust gas, is configured so that the exhaust gas communicates with a second delivery space 13-1 performing separation and the like of oil in the coolant through a communication port 12-3 arranged in the cylinder head cover from the first exhaust delivery space 12-2 and the coolant separated with the oil is discharged into a refrigeration cycle, and is configured so that a valve 14 that opens to the sucking side only when pressure inside the first delivery space of the cylinder head cover 12 rises abnormally is arranged to relieve the abnormal pressure to the suction side. Thus, pulsation pressure fluctuation is reduced, generation of vibration of the compressor itself also can be suppressed, weight increase accompanying improvement of material strength is not required to allow weight reduction, and reliability with respect to damage of a cover and the like also improves. <P>COPYRIGHT: (C)2012,JPO&INPIT |
