ABSTRACT:
A motor-compressor unit is resiliently mounted within a shell defining a lubricating oil sump. The compressor includes a primary oil pump having its inlet submerged in the oil sump to pump said oil to lubricate various compressor components. A secondary oil pump has its inlet in fluid flow communication with the oil sump. The secondary oil pump agitates said oil and increases the velocity thereof to cause any gas entrained therein to separate therefrom. The separated gas and agitated oil is directed by a distributor radially outward through the oil and over the outside surfaces of the compressor to absorb acoustical energy generated thereby.
