ABSTRACT:
A centrifugal compressor is provided with a collector for receiving refrigerant from the diffuser, and sound absorbent segments are placed within the collector and retained in place against one wall thereof. One method of retention is by way of a ring and a plurality of spring clip members. The silencer segments and the retaining ring and spring clip members are placed into the collector prior to installation of the diffuser. As the diffuser is attached to the collector, one edge engages a side of the ring so as to axially move it into its final fixed position, while at the same time causing the attached spring clip members to be placed in tension against the silencer segments to secure them in place.
