Abstract

The present invention relates to a displacement control valve of a variable displacement compressor. The displacement control valve of a variable displacement compressor according to the present invention comprises: a valve housing having a crank chamber connection hole, a discharge chamber connection hole and a suction chamber connection hole respectively receiving a crank chamber pressure, a discharge chamber pressure and a suction chamber pressure of the compressor formed inside, and a 1st guide hole passing across the discharge chamber connection hole and the crank chamber connection hole; a valve body composed of a large diameter portion and a small diameter portion to open or close the entrance to the 1st guide hole, while making a reciprocating movement; an electromagnetic solenoid for reciprocably moving the valve body with electricity; and a sleeve member having a sleeve with a larger diameter than the small diameter portion, the sleeve member connecting between the small diameter portion of the valve body and the electromagnetic solenoid. Accordingly, as the amount of opening of the valve body is restricted by the sleeve member, a suction pressure (Ps) is maintained at a constant value, independent of an increasing discharge pressure (Pd), and thus control precision is improved.
