Abstract

An injection port (27) to communicate with a compression chamber (25) during a compressing operation is formed in a stationary scroll (30). Refrigerant oil separated from refrigerant discharged from a scroll compressor (10) is introduced from the injection port (27) to the compression chamber (25) together with gas refrigerant having an intermediate pressure. The portions of teeth bottom surfaces (31a 41a) of the stationary scroll (30) and the rotary scroll (40) that face the compression chamber (25) communicating with the injection port (27) function as intermediate teeth bottom areas (36 46). The portions of the teeth bottom surfaces that are closer to the outer peripheral side end portions of laps (32 42) than the intermediate teeth bottom areas (36 46) function as suction side teeth bottom areas (35 45). Regarding the clearances between the teeth bottom surfaces (31a 41a) and the tip surfaces (42a 32a) of the laps (42 32) the values of the clearances in the suction side teeth bottom areas (35 45) are larger than those in the intermediate teeth bottom areas (36 46).
