WIPO Patent Application WO/2015/198516
Kind Code:
A1
Abstract:
A scroll compressor is provided with: a scroll compression mechanism having an orbiting scroll (30), a stationary scroll (20), and a thrust plate (19) for supporting the load of the orbiting scroll in the thrust direction; a back-pressure application mechanism for applying, as back pressure, a refrigerant gas compressed by the scroll compression mechanism to the rear surface of the thrust plate (19); and a lift amount restriction mechanism for restricting the amount of lift of the thrust plate (19) caused by the back pressure. The lift amount restriction mechanism comprises a restriction pin (60) provided with: a shaft (61) which passes through the thrust plate (19) and which has a front end portion affixed to a front housing (14); and a head (62) which has a larger diameter than the shaft (61), and the lift amount restriction mechanism allows the thrust plate (19) to be engaged with the head (62) to restrict the amount of lift of the thrust plate (19).
