Abstract

Disclosed is a suction muffler for a compressor. The suction muffler has a body and a suction pipe. The body has an expansion chamber for expanding gaseous refrigerant flowing from an evaporator, a suction chamber for drawing the refrigerant expanded in the expansion chamber, and a resonance chamber in which the refrigerant drawn into the suction chamber resonates. The suction pipe is assembled with the body and connects the suction chamber with a cylinder head of the compressor. The suction pipe provides a passage that the refrigerant in the suction chamber flows into the cylinder head. The refrigerant flows into the suction chamber after being expanded in the expansion chamber, so the noise caused by the pulsation of pressure is reduced, and the refrigerant resonating in the resonance chamber can reduce the noise of a specific frequency. Further, since the suction muffler has a simple construction having small number of components, the leakage of noise through the gaps between components can be reduced.
