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 cover20has a planar simple shape, the deformation upon molding becomes little and it can come into fully close contact with a muffler main body19. Therefore, the pressure pulsation hardly leaks through the connecting portion between the muffler main body19and the muffler cover20. The full silencing effect that the suction muffler18has is obtained and thereby noise can be reduced more effectively.
