Abstract
The subject invention provides a compressor assembly for an air conditioning system for a vehicle. The compressor assembly is of the variable displacement angle wobble plate type, and includes a housing that defines a suction cavity, a discharge cavity, and a crankcase. An electronic control valve controls the flow of a fluid between the discharge cavity and the crankcase for pressurizing the crankcase to de-stroke the compressor assembly. The control valve includes a pressure sensing member, which is responsive to a suction pressure to open fluid communication between the discharge cavity and the crankcase when the suction pressure is below a pre-determined set-point. The control valve also includes an actuator port in fluid communication with the discharge cavity for urging the member into the activated position to open fluid communication between the discharge cavity and the crankcase when the suction pressure is above the pre-determined set-point.
