Title:

CONTROL APPARATUS FOR DISPLACEMENT VARIABLE COMPRESSOR

Document Type and Number:

Japanese Patent JP2001221164

Kind Code:

A

Abstract:

To provide a control apparatus for displacement variable compressor that increases controllability of and responsiveness a discharge capacity.

A control valve has a movable wall 54 and anoperating rod 40 responding for differential pressure (PdH-PdL) between pressure monitoring points P1, P2 set on a refrigerant circulating circuit. The control valve autonomously controls opening of air supply passage 28 by valve element part 43 of the operating rod 40 to keep a target value of the differential pressure (PdH-PdL) between pressure monitoring points P1, P2 determined by electromagnetic force F of a solenoid part.
