Zusammenfassung:	A refrigerating compressor includes a compressing element and a hermetic container accommodating the compressing element, which includes a compressing chamber where refrigerant gas is compressed, and a suction muffler (118) having a sound deadening space (119) and communicating with the compressing chamber. The suction muffler (118) includes a tail tube (121) having a first end open into the hermetic container and a second end open into the sound deadening space (119), and a resonating chamber (122) formed attached to the tail tube (121) and having a resonance frequency substantially agreeing with a specific resonance frequency of the hermetic container. This structure allows the resonating chamber (122) to deaden the noises coming from vibration sounds of a suction valve or ripple sounds of refrigerant gas.
