ABSTRACT:
A suction structure for electrically-driven hermetic compressor. The compressor comprises a suction muffler having an upper outlet and a lower inlet which is formed at its bottom with means for discharging refrigerating oil, first elastic means for adsorbing vibration occurring during operation of compressor and guiding suction gas into the suction muffler which is fitted in the lower inlet of the suction muffler, second elastic means for fixing the first elastic means to the inlet of the suction muffler which is interposed between the inlet and the first elastic means without a gap therebetween, and filtering means for preventing refrigerating oil from being introduced into a cylinder which is disposed to the inlet of the suction muffler. Therefore, the suction structure can prevent refrigerating oil from being introduced in the cylinder and also prevent damage and generation of the inlet of the suction muffler due to interference therebetween is prevented, thereby improving performance of compressor.
