Suction muffler of reciprocating compressor

A suction muffler comprising a muffler inlet, a muffler outlet communicating with the muffler inlet, a plurality of reservoirs defined between the muffler inlet and the muffler outlet, and a plurality of small-diameter tubes adapted to allow the reservoirs to communicate sequentially with one another, further comprising:

• a vibration absorbing member installed on an inner wall surface of each of the reservoirs at a region where a flow of fluid sucked at a high velocity into the muffler inlet and forced to flow to the muffler outlet via the small-diameter tubes is struck against the inner wall surface, the vibration absorbing member serving to absorb vibrations generated due to pulsations of the fluid flow resulting from the striking of the fluid flow against the inner wall surface, thereby attenuating flow noises resulting from the vibrations, wherein the vibration absorbing member is provided with a plurality of wave interference grooves at a surface thereof, against which the fluid flow is struck, each of the wave interference grooves having a depth corresponding to ⅛ or more of a maximum displacement of the pulsations.
