ABSTRACT:
A compressor assembly for pumping a recirculating refrigerant including input and output shafts rotatably supported within a housing and a pressure responsive clutch disposed therebetween for selectively translating torque from the input shaft to the output shaft to drive the compressor. An auxiliary clutch compressor is employed for generating an auxiliary refrigerant discharge pressure and a control valve is moveable between first and second positions to either route refrigerant discharge pressure away from the clutch or to bear upon the clutch so as to translate torque between the input and output shafts.
