Abstract
A hermetic compressor is equipped with a suction muffler including: a muffling space having two rooms; a communication space to communicate these two rooms with each other; a first communication passage to communicate a movable valve with the muffling space and extending to an opening into the muffling space; and a second communication passage to communicate an enclosed container with the muffling space and extending to an opening into the muffling space. The openings into the muffling space from the first and the second communication passages are disposed in one of the two rooms, and the other room of the two rooms forms a resonance muffler whose resonance frequency matches a cavity resonance frequency of the enclosed container. The configuration can provide the hermetic compressor with a reduced noise emission and a high compression efficiency.
