<p>A resistive muffler (50, 250, 350) attenuates sound generated by the gas intake and suction valves of a refrigerant compressor (2). The resistive muffler (50, 250, 350) is assembled inline with the suction gas flow of the compressor and is positioned within the compressor housing (16). The resistive muffler (50, 250, 350) includes a muffler housing (260, 360) having an intake end (54, 254, 354) and an exhaust end (52, 252, 352). An acoustic foam assembly (56, 266, 366) is incorporated into the muffler housing (260, 360). The acoustic foam assembly (56, 266, 366) is selected on the basis of its ability to absorb sound over a broad range of frequencies and remains chemically inert when exposed to the compressor fluids at elevated temperatures of operation.</p> |
