ABSTRACT:
An improved muffler system for a compressor assembly where the muffler is disposed within the compressor housing and a peripheral edge of the muffler abuts, and expansively engages, the interior surface of the housing in an interference fit relationship. The compressor pump is attached to the muffler where the pump is substantially thermally and vibrationally isolated from the housing. The muffler, the compressor pump and the compressor housing define a series of chambers in which noise generated by the compressor pump is dissipated. The dimensions of the chambers are chosen to cause acoustical waves having specific, undesirable frequencies to cancel each other out.
