Abstract:
A suction muffler for a compressor comprising:an inlet for introducing a refrigerant into the suction muffler; a chamber for temporary storage of the refrigerant and dropping a pressure of the refrigerant by means of a sudden increase of a volume of the refrigerant; a resonator for attenuating a noise of a specific frequency; a refrigerant supply tube for leading the refrigerant from the chamber to a cylinder, thereby stopping transmission of a pulsating flow occurred by the piston movement in the cylinder to outside of the refrigerant supply tube and preventing transmission of a noise from a suction valve and a discharge valve to outside of the suction muffler, wherein the chamber includes a vibration member having a vibration frequency corresponding to a pulsation frequency occurred at the refrigerant supply tube.
