ABSTRACT:
A muffler for a hermetic rotary compressor including a muffler body forming a plurality of noise reducing spaces in which refrigerant gas flows; a discharge port formed on the muffler body so as to be located on the nose reducing spaces side; and a guide cover coupled to an inner wall of the muffler body in radial direction for guiding the refrigerant gas flowing in the noise reducing spaces to be discharged to the discharge port, and therefore the noise generated during the discharge of the compressed refrigerant gas to inside a sealed chamber, and a flow resistance for the discharged refrigerant gas is reduced, whereby the electric power consumption is reduced, and the structure and assembling processes can be simplified.
