A control valve (301) includes a body (56,305) having a main passage communicating a discharge chamber with a crankcase and a sub-passage communicating the crankcase with a suction chamber. A main valve (90,22) is provided in the main valve passage and a sub-valve is provided in the sub-valve passage. The control valve further includes a pressure-sensing portion (6) for receiving the suction pressure of the suction chamber and generating a drive force exerted in an opening direction of the main valve (90,22) in accordance with the magnitude of the suction pressure, and a solenoid (3) for generating a drive force in a closing direction of the main valve (90,22) in accordance with the amount of current supplied. The pressure-sensing portion (6) is provided on one side of the main valve and the solenoid (3) is provided on the other side thereof. The configuration of the control valve is such that after the main valve element (330) has seated on the main valve seat (22) the main valve element (330) is displaceable integrally with the valve seat (22) while the main valve being closed. |
