Abstract: A compressor capable of reducing oil circulation rate with a simple structure is provided. A compressor 100 in which a piston 136 is caused to reciprocate, so that a refrigerant gas drawn from a suction chamber 141 via a suction hole 103a is compressed and discharged, includes: a partition member 150 dividing the suction chamber 141, into which the refrigerant gas flows from a suction passage 104a, into a first space 141a connected to the suction passage 104a and a second space 141b connected to the suction hole 103a; and a communication passage 150a configured to allow the first space 141a and the second space 141b to be in communication with each other, and introduce the refrigerant gas, from which lubricating oil has been separated, from the first space 141a to the second space 141b.

Abstract: A variable displacement compressor which prevents leakage of a refrigerant flowing directly into a suction chamber without passing via a crank chamber at a time of a minimum discharge displacement operation, thus making it possible to prevent an increase of a minimum discharge displacement by increasing a refrigerant pressure in the crank chamber, and in addition, making it possible to prevent insufficient lubrication of sliding portions and the like in the crank chamber.

Abstract: In a flow rate measuring device for measuring a refrigerant discharge flow rate in a variable displacement compressor, a check valve is used as a throttle for measuring the flow rate to thereby simplify the configuration while an anti-backflow function of the check valve is secured. The device includes a spool 252 receiving, at one pressure receiving surface, a pressure on an upstream side of the check valve and, at an opposite pressure receiving surface, a pressure on a downstream side to slide in a housing 251 such that a differential pressure therebetween balances a biasing force of a compression coil spring 253, and a sensor detecting a position of the spool 252 to measure the flow rate (magnetic force measuring unit 256). The housing 251 includes a position regulation part (regulation surface 251a3) which regulates a position of the spool 252 to close a gap between the hosing 251 and the spool 252 when the differential pressure falls below a predetermined value.

Abstract: Variable displacement compressor 100 has second control valve 350 for adjusting the opening degree of pressure release passage 146. Second control valve 350 includes partition member 351, which partitions valve chamber 351c and back pressure chamber 351d, and has side wall 351a surrounding valve portion 352b of spool 352, and end wall 351b connected to one end side of side wall 351a and through which shaft portion 352b of spool 352 penetrates. Furthermore, in second control valve 350, end surface 351a1 opposite to the end wall of the side wall of partition member 351 abuts on the wall surface opposite to the back pressure chamber of the valve chamber 351c. When the valve portion 352b of spool 352 abuts on the wall surface, pressure receiving portion 352a of spool 352 abuts on end wall 351b.
