Abstract
The oil sump and suction plenum of a hermetic compressor are in continuous fluid communication through an oil equalization port assembly. Additionally, communication is established between the oil sump and the suction plenum if pressure in the oil sump is greater than that in the suction plenum by more than a few pounds. Multiplexing is established through a port in the suction plenum.
