<p><P>PROBLEM TO BE SOLVED: To provide a variable displacement compressor reducing pressure in a compressor while contributing reduction of environmental load and advantageous in productivity and economy of the compressor. <P>SOLUTION: The variable displacement compressor 2 compresses refrigerant sucked from a refrigerant circuit 62 and changes delivery quantity to set suction pressure to a set value by pressure regulation of a crank chamber 28, and delivery compressed refrigerant gas to a delivery chamber 52. The compressor is provided with a housing 6, a cylinder bore 24 formed in a housing and compressing refrigerant, a piston 26 reciprocating in a cylinder bore, a passage 70 establishing communication between a delivery chamber and a crank chamber, and a delivery pressure adjusting devices 74, 76 provided in the passage permitting discharge of compressed refrigerant gas from the delivery chamber to the crank chamber at a time of high pressure and regulating flow rate of compressed refrigerant gas from the delivery chamber to the crank chamber at a normal time. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
