Abstract: A refrigeration compressor incorporating an improved suction muffler is disclosed. The suction muffler provides dual sound attenuating chambers within a single housing, which housing is secured to the suction inlet conduit extending between the motor cover and suction inlet for the compressor. The suction inlet conduit is increased in diameter between the motor cover and the compressor inlet to provide a stepped portion which operates to reflect pressure waves. Integrally formed openings in the sidewall of the conduit provide communication with each of the two chambers and the respective chambers may be tuned to attenuate different specific frequencies. Internal integrally formed baffles within each of the chambers serve to reduce standing waves within the chambers as well as adding stiffness to the muffler.
