<P>PROBLEM TO BE SOLVED: To provide a displacement control valve of a variable displacement swash plate type compressor miniaturizable more than a displacement control valve disclosed in Patent Disclosure H7-127566. <P>SOLUTION: This displacement control valve of a clutchless variable displacement swash plate type compressor, controls delivery capacity of the variable displacement swash plate type compressor, by opening and closing a valve hole 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, an inside control valve for opening and closing the valve hole by a valve element for operating in response to the expansion-contraction of a pressure sensitive member for sensing suction pressure, and an operation switching device connected to the inside control valve and switching the inside control valve to an operation state of opening and closing the valve hole by the valve element in response to the expansion-contraction of the pressure sensitive member and a nonoperating state of opening the valve hole by the valve element regardless of the expansion-contraction of the pressure sensitive member. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
