Abstract
In a hermetic compressor in a freezing refrigerating system or an air-conditioning system such as a refrigerator or a showcase, a construction is disclosed for intending to provide a low-noise hermetic compressor by effectively attenuating a pressure pulsation having occurred in a compression chamber with a suction muffler. By this construction, since a muffler coverhas a planar simple shape, the deformation upon molding becomes little and it can come into fully close contact with a muffler main body. Therefore, the pressure pulsation hardly leaks through the connecting portion between the muffler main bodyand the muffler cover. The full silencing effect that the suction mufflerhas is obtained and thereby noise can be reduced more effectively.
