PROBLEM TO BE SOLVED: To provide a control valve for a variable displacement compressor which improves flexibility of design of a valve part and a pressure sensitive part, in the control valve for the variable displacement compressor having the pressure sensitive part.SOLUTION: A control valve 1 includes: a body 5 formed of a volume chamber 22, a valve chamber 26 and an actuation chamber 28 from one edge side; a valve body which is supported slidably on the body 5, receives a crank pressure in the volume chamber 22 on one edge side, on the other hand, receives a pressure to be sensed in the actuation chamber 28 on the other edge side and attaches to and detaches from a valve seat disposed between the valve chamber 26 and the volume chamber 22 to open and close a valve body; and a power element 6 which senses the crank pressure in the volume chamber 22 and biases the valve body in the valve opening direction in accordance with the crank pressure. A pressure chamber 88 into which the crank pressure of the volume chamber 22 is introduced is formed on the side opposite to the volume chamber 22 with respect to the valve chamber 26, and an actuation surface 87 which receives the crank pressure in the pressure chamber 88 is provided on the valve body. |
