<P>PROBLEM TO BE SOLVED: To provide a control valve for an clutch type variable displacement compressor capable of improving response of the compressor at the time of start as compared to a conventional compressor. <P>SOLUTION: The control valve 50 for the clutch type variable displacement compressor 10 includes a liquid discharge passage for bleeding maintaining communication between a Pc port 58 and a Ps port 57. Communication and shut off of the liquid discharge passage for bleeding is controlled by movement of a pressure sensitive member constructing a pressure sensitive mechanism 66. When the compressor 10 is started from a stop condition, the pressure sensitive member positions to communicate the liquid discharge passage for bleeding while balance pressure in the compressor 10 at a time of stop of the compressor 10 is maintained, pressure in a suction pressure area drops with accompanying start of the compressor 10, and the pressure sensitive member moves in a direction shutting off the liquid discharge passage for bleeding when pressure in the suction pressure area reaches predetermined pressure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
