CONTROL VALVE OF VARIABLE DISPLACEMENT COMPRESSOR

摘要

PURPOSE: A control valve for a variable capacity compressor is provided to reduce driving loads by forming ports connected to a crank chamber of the variable capacity compressor on the part of a body of the outside of a movable member which rectilinearly moves. CONSTITUTION: A control valve for a variable capacity compressor comprises an operating unit (100) and a driving unit (200). The operating unit includes a first port connected to one side of the crank chamber of the variable capacity compressor; a second port connected to one side of a suction chamber of the variable capacity compressor; a third port connected to a discharge chamber of the variable capacity compressor; and a fourth port connected to the other side of the crank chamber. The operating unit controls pressure of the crank chamber and the suction chamber. The driving unit is connected to the operating unit and drives the operating unit when power is supplied. The operating unit includes a body and a movable member.
