<P>PROBLEM TO BE SOLVED: To enable a control valve for a variable displacement compressor, which operates by sensing a differential pressure between discharge pressure and suction pressure or between the discharge pressure and crankcase pressure, to enhance compression efficiency inside the compressor. <P>SOLUTION: In the control valve for a variable displacement compressor, after a valve element 14 on a high pressure side closes a valve hole 11, a valve element 15 on a low pressure side opens a valve hole 23. Therefore, it is possible to eliminate a region in which both the valves on the high pressure side and the low pressure side are simultaneously open. This makes it possible to prevent refrigerant introduced into a crankcase from being immediately delivered, which makes it possible to obtain a sufficient compression efficient. <P>COPYRIGHT: (C)2007,JPO&INPIT |
