Abstract (en)
[origin: EP2894341A1] To provide a compressor which can produce a high noise reduction effect by sufficiently reducing pressure pulsations of a refrigerant discharged from a muffler outlet. A rotary compressor 1 includes: a compression mechanism 20 which compresses a refrigerant with rotation of a shaft 123; and a muffler 30 which is provided around the shaft 123 opposite to the compression mechanism 20 and receives the refrigerant discharged from the compression mechanism 20. A muffler outlet 38 for discharging the refrigerant inside the muffler 30 opens annularly along an outer periphery of the shaft 123. A constriction 36, at which a passage of the refrigerant flowing toward the muffler outlet 38 is narrowed in the length direction of the shaft 123, is formed around the shaft 123 inside the muffler 30.
