CAPACITY CONTROL VALVE OF A VARIABLE COMPRESSOR CAPABLE OF IMPROVING CONTROL ACCURACY BY OFFSETTING THE PRESSURE OF AN EXHAUST CHAMBER TO A VALVE BODY

摘要

PURPOSE: A capacity control valve of a variable compressor is provided to prevent the rotation of a valve body and reduce the vibration of a valve body caused by the driving of an electronic solenoid and the pulsation of refrigerant.;CONSTITUTION: A capacity control valve of a variable compressor comprises a valve housing, a valve body, an electronic solenoid, and a sleeve. The valve body opens and closes the inlet of a first guiding hole by being reciprocated. The electronic solenoid comprises a moving steel core, a housing, and a fixed steel core and is installed in the circumference of the moving steel core. The moving steel core is reciprocated. The solenoid housing encloses an electronic coil. The fixed steel core is installed in the electronic coil. The sleeve offsets the force generated by an exhaust chamber.;COPYRIGHT KIPO 2012
