Beschreibung
Zusammenfassung:	A scroll compressor includes a housing and a compression mechanism. The compression mechanism includes a compression chamber. The housing includes an intermediate pressure chamber into which refrigerant having an intermediate pressure is introduced from an external refrigerant circuit. The intermediate pressure is higher than a suction pressure of refrigerant drawn into the compression chamber and lower than a discharge pressure of the refrigerant discharged from the compression chamber. The intermediate pressure chamber and the compression chamber in a process of compression are connected to each other by an injection passage. The injection passage includes a muffler.
