REFRIGERANT COMPRESSOR

摘要

Suction muffler (137) includes tail tube (147) having one end opening to sound deadening space (139) and communication tube (155) having one end opening to sound deadening space (139), where respective openings (161), (163) are at the middle of sound deadening space (139) and side branch resonator (149) having a resonance frequency that substantially matches a high-pass resonance frequency of hermetic container is arranged at tail tube (147). According to a refrigerant compressor having such a configuration, generation of noise caused by resonance of hermetic container can be reduced by suppressing radiation of noise that substantially matches the high-pass resonance frequency of hermetic container and further sound-deadening the same with side branch resonator (149).
