Document Type and Number:
Japanese Patent JP5878703
Kind Code:
B2
Abstract:
A variable displacement compressor control valve is provided, which can reduce a time required until a discharge capacity becomes large at a time of actuation of a compressor without reducing an operation efficiency of the compressor. An in-valve release passage 16 for releasing a crank chamber pressure Pc to a suction chamber of the compressor through a Ps inlet/outlet port 27 is provided, a sub valve element 17 which opens and closes the in-valve release passage 16 is provided, and under a situation in which a valve port 22 is closed by a main valve element 15, two forces that are a force corresponding to a suction pressure Ps (contraction force of a bellows device 40) and a force corresponding to a differential pressure of the crank chamber pressure Pc and the suction pressure Ps act on the sub valve element 17 in a direction to open the in-valve release passage 16.
