Patent ID: 7478996

Claim:
A reciprocating compressor having an assembly structure of a suction muffler, comprising: a casing for connecting a gas suction pipe with a gas discharge pipe; a frame elastically installed in the casing; a reciprocating motor supported by the frame; a piston coupled with a mover of the reciprocating motor and compressing a refrigerant gas while linearly reciprocating in a cylinder; a suction valve for opening or closing a suction flow channel of the piston; a discharge valve for opening or closing a discharge side of the cylinder; a plurality of resonance springs for elastically supporting the piston in a direction of motion and inducing the resonance movement; and a suction muffler coupled with the piston and guiding the refrigerant gas to the suction flow channel of the piston and simultaneously muffling a suction noise generated when opening or closing the suction valve, wherein a supporting unit is formed on an inner circumferential surface of a resonant container of the suction muffler and a baffle is supported in the resonant container by the supporting unit, wherein the supporting unit comprises a first protrusion and a second protrusion, and an insertion groove is formed between the first and second protrusions along the inner circumferential surface of the resonant container, and wherein the first protrusion has a setting height lower than a setting height of the second protrusion in order to permit insertion of the baffle past the first protrusion and into the insertion groove.
