<p>A gas compressor having a suction muffler assembly for attenuating both high and low frequency noise produced by the inlet valving of the compressor, including an inner suction tube extending from the compressor intake to a muffler and a by-pass tube surrounding the suction tube with the by-pass tube having by-pass apertures in the upper end thereof, whereby the effective cross-sectional area of the suction intake tube may be reduced thereby attenuating low frequency noise while at the same time retaining adequate gas inflow to the compressor intake.</p> |
