Abstract
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 () having a sound deadening space () and communicating with the compressing chamber. The suction muffler () includes a tail tube () having a first end open into the hermetic container and a second end open into the sound deadening space (), and a resonating chamber () formed attached to the tail tube () and having a resonance frequency substantially agreeing with a specific resonance frequency of the hermetic container. This structure allows the resonating chamber () to deaden the noises coming from vibration sounds of a suction valve or ripple sounds of refrigerant gas.
