    • 专利摘要:
    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.

    Claim
    1. A method of reducing noise in a sealed compression refrigeration unit by damping the noise produced by the moving parts of the motor compressor, partially placed in the oil volume, is distinguished by the fact that in order to increase the efficiency of noise suppression, a vapor-liquid layer is created in the upper layer of the oil volume by mixing oil with part of the vapor circulating in the refrigerant unit.
