Abstract
A suction noise attenuator adapted for mounting on a tubular, suction conduit of a gas compressor, the conduit having a gas port through the wall thereof, the attenuator having a shell formed with generally opposed, first and second end walls and generally opposed first and second side walls, all of the walls having proximal and distal portions relative to the suction conduit, the proximal portions being resiliently deformable and the combined edges thereof providing a substantially continuous perimeter mounting face, a distal wall interconnecting the distal portions of all the walls to define an attenuation cavity, the mounting face further defining an inlet to the cavity, the edges of the end walls being concave and adapted to conform substantially to the periphery of the conduit as the attenuator is pressed thereagainst, at least one locator device on the shell adapted for coupling with at least one locator device on the conduit for operatively positioning the attenuator on the conduit to connect the port and cavity in fluid communication, and shoulders on an exterior surface of the shell adapted for retaining a clip fastening device in operative position thereon for securing the attenuator to the conduit.
