Abstract
A radial refrigerant compressor assembly for use in automotive refrigerant systems and capable of being cycled between on and off conditions having a fluid passageway extending between the bottom portion of the discharge chamber which operates at discharge pressure and the suction chamber which operates at a reduced suction pressure. A valve is disposed within the fluid passageway and regulates the flow of lubricant between the discharge and suction chambers under the force of the pressure differential existing between these chambers just after the compressor is cycled on and just after the compressor is cycled off.
