Abstract

Disclosed is a displacement control valve for a variable displacement compressor. The displacement control valve comprises: a valve housing having a crank chamber connection hole, a discharge chamber connection hole and a suction chamber connection hole formed therein, which respectively receive the pressure from the compressor crank chamber, discharge chamber, and suction chamber, and further having a first guide hole penetratingly formed therein, which is positioned between the discharge chamber connection hole and the crank chamber connection hole; a valve body which, whilst moving reciprocally, opens and closes the opening of the first guide hole; and an electronic solenoid which causes the reciprocal movement of the valve by applying electric current; a sleeve which connects the electronic solenoid and the valve body; and an air extraction valve which controls the connection between the crank chamber and the suction chamber by movement of the sleeve. Thus, when the pressure in the compressor crank chamber increases rapidly, the pressure can be quickly released via the suction chamber due to the air extraction valve.
