Abstract (en)

[origin: EP1283361A1] A control valve for a variable capacity compressor is provided, in which there is provided a valve element 15 driven by an action of a bellows device 22 arranged in a bellows receiving chamber 17 into which suction pressure Ps of the variable capacity compressor is introduced, generated load of an electromagnetic coil device 30 responds to generated load of the bellows device 22, setting pressure of the bellows device 22 is variably set in response to the generated load of the electromagnetic coil device 30, and pressure in a crankcase of the variable capacity compressor is controlled in response to opening of the valve element 15, thereby controlling capacity of the variable capacity compressor, the control valve being characterized in that a plunger chamber 53 of the electromagnetic coil device 30 communicates with the bellows receiving chamber 17 by an equalizing hole 49 and the suction pressure Ps is introduced into the plunger chamber 53. <IMAGE>
