<p>A capacity control valve of the present invention includes a communication path (31) through which a discharge chamber (11) and a control chamber (12) are allowed to communicate with each other; a valve chamber (36) in the middle of the communication path (31); communication paths (32, 31b) through which a suction chamber (13) and the control chamber (12) are allowed to communicate with each other; a valve chamber (36) in the middle of the communication path (32) ; a valve body (40) including a first valve part (41) that opens and closes the communication path (31) and a second valve part (42) that opens and closes the communication path (32), the first and second valve parts being placed in the valve chamber (36) and performing the opening and closing operation in a manner opposite to each other; and a solenoid (60) for moving the valve body (40) . The valve body (40) has a pressure receiving part (44) at its end that is across the second valve part (42) from the first valve part (41), and the pressure receiving part (44) receives a control-chamber pressure. The pressure receiving area (S3) of the pressure receiving part (44) is substantially the same as the difference between the pressure receiving area (S2) of the second valve part (42) and the pressure receiving area (31) of the first valve part. Thereby, the valve is reduced in size, an influence of the pressure in the control chamber is minimized, and stable capacity control with excellent response is enabled.</p> |
