Abstract
In a compressor having an oil sump located therein, a restricted communication is provided between the oil sump and the suction plenum. As a result, froth generation due to a rapid pressure drop in the oil sump is reduced. A relief valve is provided to limit the pressure differential between the suction plenum and the oil sump.
