Abstract (en)
[origin: EP3415756A1] The present invention provides a compressor including a valve mechanism that suppresses transmission of pressure pulsations at the time when a flow rate is low, and reduces a pressure difference between an inlet port and a suction chamber during a stop of the compressor so as to hasten startability of the compressor. A check valve forming body 30 includes: a valve housing 31 that includes an inflow port 38 and an outflow port 39, the inflow port 38 having a valve body housing space 32 therein and communicating with the inlet port, and the outflow port 39 communicating with the suction chamber; a valve body 41 that is housed in the valve body housing space 32 and varies a communication state between the inflow port 38 and the outflow port 39; and a spring 51 that urges the valve body 41 in a direction to block the communication between the inflow port 38 and the outflow port 39. The valve housing 31 is loosely fitted to an annular groove 26 formed in a cylinder head 4 in such a manner that axial movement thereof is allowed, blocks a working fluid that flows on the outside of the valve housing 31 in a state of abutting a peripheral edge portion of the annular groove 26 on the suction chamber side, and allows a flow of the working fluid on the outside of the valve housing 31 in a state of separating from the peripheral edge portion of the annular groove 26 on the suction chamber side.
