摘要： A valve element disposed in the valve chamber of a control valve body of a control valve for variable capacity compressors performs opening and closing operations by a plunger. The upper end of the valve element of this control valve body is inserted in the pressure chamber, while the lower end of the valve element is inserted in the plunger chamber of the solenoid excitation part. And the plunger chamber and the pressure chamber communicate with each other through a cancel hole formed in this valve element.

摘要： A control valve for a variable capacity compressor; wherein an opening degree of a valve member disposed in a coolant gas passage for communicating a discharge pressure region of the variable capacity compressor with a crankcase thereof is made adjustable by a magnetization action of a solenoid, thereby causing an inclination angle of a wobble plate to change and also causing a discharging capacity of the compressor to change; and which is characterized in that the main valve body comprises a solenoid, a pressure sensitive chamber provided with bellows and a valve chamber provided with the valve member, and that the solenoid is provided with a plunger connected with one end of a stem, whose other end of the stem being detachably contacted with a stopper of the bellows, and the other end of the plunger being linked to a rod to be contacted with the valve member.
