摘要： A seal structure sealing a fitted part between the guide surface of a bearing part and a shaft part to prevent a fluid from flowing in a direction from a high-pressure fluid side to a low-pressure fluid side. The seal structure comprises a seal ring storage part having a radial contact surface surrounding the shaft part which is formed on the high-pressure fluid side of the bearing part and a seal ring disposed in the seal ring storage part, allowing its side surface facing the contact surface to come into contact with the contact surface, and allowing its inner peripheral surface to be fitted to the outer peripheral surface of the shaft part. The seal ring is formed in such a relative dimension that, even if elastically deformed by the pressure of the sealed fluid, the elastically deformed expanded portion thereof is not brought into contact with the peripheral surface of the seal ring storage part.

摘要： 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 (S1) 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.
