A variable displacement compressor contains a displacement control valve system for controlling a displacement of fluid for compression. The displacement control valve system comprises a pressure sensing means for sensing a pressure of a suction chamber (63) or a pressure of a crank chamber (23), a transmission rod (101) supported so as to be capable of passing through a valve casing with an end thereof being in contact with this pressure sensing means, a valve body (127) for opening/closing a communication path between a discharge chamber (65) and a crank chamber (23) in correspondence to extension or contraction of the pressure sensing means while the other end of the transmission rod (101) is in contact with the valve body (127), and a solenoid (123) for applying an electromagnetic force to this valve body (127). A valve shaft (131) of the valve body (127) is supported so as to be capable of passing through a stator (111) of the solenoid (123). The valve shaft (131) is protruded into a plunger chamber (117) of the solenoid (123). The plunger chamber (117) is made to communicate with the suction chamber (63).
