Document Type and Number:
WIPO Patent Application WO/2016/006565
Kind Code:
Provided is a compressor in which a check valve is provided to an injection passage formed in a housing member, said compressor being capable of inhibiting pressure loss of injected refrigerant. The compressor is provided with: a fixed scroll (30) having, formed therein, an injection passage (31) communicating with a compression chamber (Sc); a check valve (50) provided to the passage (31); and an injection pipe (25) for supplying a refrigerant to the passage (31). The check valve is provided with: a valve main body (51) which is slidably disposed in the passage (31); and a valve pressing member (52) which, when the flow of the refrigerant from the compression chamber to the pipe (25) is stopped, restricts movement of the valve main body towards the pipe (25) side. A central hole (51a) is formed in the valve main body. Peripheral holes (52a) facing the periphery (51b) of the valve main body are formed in the valve pressing member. When the refrigerant is being supplied to the compression chamber from the pipe (25), the refrigerant is supplied to the compression chamber through the peripheral holes (52a) and the central hole (51a). When the refrigerant is stopped by the check valve, the central hole (51a) is closed by the valve pressing member, and the peripheral holes (52a) are closed by the valve main body.
