Abstract (en)
[origin: EP2163766A2] A scroll compressor includes: an orbiting scroll (200) and a fixed scroll (100) which mesh with each other so as to compress a refrigerant; a discharge pressure space (5) into which the refrigerant is discharged from the compression chamber (4); an orbiting scroll end plate surface (202) on which the orbiting scroll comes into sliding contact with the fixed scroll; a fixed scroll end plate surface (102) on which the fixed scroll comes into sliding contact with the orbiting scroll; a groove-shaped pressurizing pocket space (601) which is provided in the orbiting scroll end plate surface or the fixed scroll end plate surface so as to be located on the outer peripheral side of the compression chamber; a pressure adjusting valve (600) which is provided in a passageway connecting the discharge pressure space with the pressurizing pocket space; and a pressurizing passageway (606) which is provided between the pressure adjusting valve and the pressurizing pocket space, wherein the refrigerant flows from the discharge pressure space to the pressurizing pocket space in the case where the differential pressure between the discharge pressure space and the pressurizing passageway is equal to a predetermined value.
