Abstract

This scroll compressor is provided with a resonance unit (90) that attenuates vibration of a prescribed frequency generated by a refrigerant gas compressed by a fixed scroll and an orbiting scroll. A center-side compression chamber (20A) that communicates with a discharge port (21C) formed on an end plate of a fixed scroll is formed between a spiral wrap (21B) of the fixed scroll and a spiral wrap (22B) of the orbiting scroll. A back-side compression chamber (20B) adjacent to the center-side compression chamber (20A) is formed between the back side of the spiral wrap (21B) and the ventral side of the spiral wrap (22B), a ventral-side compression chamber (20C) adjacent to the center-side compression chamber (20A) is formed between the ventral side of the spiral wrap (21B) and the back side of the spiral wrap (22B), and the refrigerant gas is guided to the resonance unit (90) from the ventral-side compression chamber (20C) in a state in which the refrigerant gas compressed in the center-side compression chamber (20A) flows into the ventral-side compression chamber (20C) via the discharge port (21C).
