Abstract:
Provided is a scroll compressor etc. having good performance and high reliability. This scroll compressor (100) comprises a compressing mechanism part (2) that compresses, in a compression chamber (C1), a refrigerant suctioned in via a suction chamber (J1) and discharges the compressed refrigerant via a discharge port (J2). The compressing mechanism part (2) has a fixed scroll (21) that includes a spiral fixed lap (21b) and an orbiting scroll (22) that includes a spiral rotary lap (22b). The compression chamber (C1) is formed between the fixed lap (21b) and the rotary lap (22b). The compressing mechanism part (2) has a liquid injection hole (H1) that guides a liquid refrigerant to the compression chamber (C1), and has a gas injection hole (H2) that guides a gas refrigerant to a compression chamber (C2). The liquid injection hole (H1) is provided at a position closer to the suction chamber (J1) than the gas injection hole (H2).
