ABSTRACT:
A suction gas feed assembly for a gas compressor unit having a shell, an electric motor driven dual piston compressor mounted therein having dual suction ports, one end of the motor being interconnected with and adjacent the compressor, the other end of the motor being substantially unencumbered, the feed assembly consisting of an end cap having a circumferential side wall and a top wall and adapted to be mounted within the shell with the side wall in substantial sealing contact with the unencumbered end of the motor to provide a suction plenum substantially containing the unencumbered end, dual suction conduits each having one of its ends mounted in an aperture in the side wall of the end cap, the apertures being spaced apart on the side wall a distance of at least about one eighth the total circumferential dimension of the side wall, the other ends of the conduits adapted to be mounted in communication with the suction porting of the compressor, intermediate portions of each of the conduits lying in contiguous relationship, a housing surrounding the intermediate portions and spaced therefrom to provide a substantially closed attenuator cell containing the intermediate portions, and gas passages in each of the intermediate portions placing each of the conduits in fluid communication with the cell.
