Abstract

The control valve comprises a valve rod having a valve body part; a valve main body provided with a valve chamber having a valve port to/from which the valve body part contacts/separates, a discharge pressure refrigerant inlet for introducing the refrigerant from a compressor, and a refrigerant outlet communicating with a crank chamber of the compressor; an electromagnetic actuator having a plunger for moving the valve rod in the valve closing direction; a pressure sensing chamber in which suction pressure is introduced from the compressor; and a pressure sensitive response member for pressing the valve rod in the valve opening direction corresponding to the pressure in the pressure sensing chamber, wherein the valve rod is fitted to the plunger having a predetermined diametrical directional clearance so as not to be influenced from the lateral deviation and inclination of the plunger.
