ABSTRACT:
An improved suction noise muffler for a hermetic compressor which is capable of discharging residual oil which is introduced together with a refrigerant gas using the weight of the oil itself by equipping with an oil discharging valve unit at an oil discharging unit, which muffler includes a guide path for guiding a refrigerant gas introduced through an inlet portion along a connected path, resonant and noise reducing chambers formed for reducing noise of the refrigerant gas which flows along the guide path, and an oil discharging section having an upper discharging section in order for the oil introduced into the resonant and noise reducing chambers together with refrigerant gas to be discharged through the discharging valve unit operated by the weight of the oil, with the oil discharging valve unit being formed in the upper discharging section.
