<P>PROBLEM TO BE SOLVED: To provide a displacement control valve of a variable displacement swash plate type compressor miniaturizable more than a conventional displacement control valve. <P>SOLUTION: This displacement control valve B of the variable displacement swash plate type compressor, controls delivery capacity of the variable displacement swash plate type compressor, by opening and closing a valve hole 106 formed of a communicating passage between a delivery chamber and a crank case of the variable displacement swash plate type compressor; and has the valve hole always communicating with the delivery chamber, a valve element 109 for opening and closing the valve hole, a support rod 111 slidably inserted into a support hole arranged in alignment in the valve hole and connected to the valve element, and an electromagnetic solenoid 120 for driving the valve element. Suction pressure or crank case pressure of the variable displacement swash plate type compressor, is impressed on an end part on the side separating from the valve element of the support rod. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
