Abstract
The present invention discloses a suction muffler for a hermetic compressor which reduces noise of refrigerant. A plate film operating as a kind of flow resistance is provided on a refrigerant suction passage in various shapes and specific positions. Therefore, the suction muffler can effectively reduce pressure pulsation transferred to the outside and guarantee flow efficiency, although the refrigerant is directly sucked thereinto.
