Abstract
A muffler system for a compressor includes an expansion chamber muffler for attenuating sound pressure pulses and an acoustic muffler for filtering high-frequency pressure pulsations. The acoustic muffler is connected inline along the discharge side of the compressor between the discharge port of the cylinder head and a discharge tube in fluid communication with the outlet port of the compressor housing. A conduit is in fluid communication between the outlet port of the compressor housing and the condenser to supply the flow of refrigerant therebetween. Interposed adjacent the compressor housing, but exterior to the compressor housing is an expansion chamber muffler in fluid communication with the conduit for further attenuating pressure pulses generated by operation of the compressor.
