Title:
CONTROL VALVE FOR VARIABLE DISPLACEMENT COMPRESSOR
Document Type and Number:
Japanese Patent JP3731434
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control valve for a variable displacement compressor, capable of improving in the controllability and responsibility of a discharge displacement.
SOLUTION: A valve element 43 controls the opening of an air supply passage 28 corresponding to the position of a valve chest 46. A pressure sensitive member 54 is displaced corresponding to differential pressures PdH-PdL between two pressure monitoring points P1, P2 set in a cooling medium circulation circuit, and the displacement is reflected by the positioning of the valve element 43 so that the discharge displacement of the compressor can be changed to the side of cancelling the variation of the differential pressures PdH-PdL. A solenoid portion 60 changes force granted to the valve element 43 so as to change a set differential pressure as a reference to the positioning operation of the valve element 43 with the pressure sensitive member 54.
