Gas passage structure with improved seal members in a compressor

摘要

The number of seal members relating to a gas flow control valve can be reduced. A displacement control valve 25 is attached to a fixed coupling surface 193 on the outer wall surface of a rear housing 19. A gasket 45 is interposed between end surfaces 362 and 414 of the displacement control valve 25 side and a coupling surface 193. A sealing elastic layer 452 of the gasket 45 is in close contact with the end surfaces 362 and 414, and a sealing elastic layer 453 is in close contact with the coupling surface 193. A pressure supply passage 30 and a gas passage 413 are communicated with each other via a communication port 454 on the gasket 45. A pressure supply passage 31 is communicated with an insertion recess 33 that is communicated with a valve port 431.
