    • A capacity control valve has a communication path (31) for communicating a discharge chamber (11) and a control chamber (12); one valve chamber (36) in the middle of the communication path (31); communication paths (32, 31b) for communicating a suction chamber (13) and the control chamber (12) ; the other valve chamber (36) in the middle of the communication path (32); a valve body (40) including a first valve section (41) that opens and closes the communication path (31) and a second valve section (42) that opens and closes the communication path (32), the first and second valve sections 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 section (44) at its end section that is across the second valve section (42) from the first valve section (41), and the pressure receiving section (44) receives pressure in the control chamber. The pressure receiving area S3 of the pressure receiving section (44) is substantially the same as the difference between the pressure receiving area S2 of the second valve section (42) and the pressure receiving area S1 of the first valve section. 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.
    • 容量控制阀具有用于连通排出室(11)和控制室(12)的连通路径(31)。 在所述连通路径(31)的中间的一个阀室(36); 用于连通吸入室(13)和控制室(12)的连通路径(32,31b)。 连通路径(32)中间的另一个阀室(36); 包括打开和关闭连通路径(31)的第一阀部分(41)和打开和关闭连通路径(32)的第二阀部分(42)的阀体(40),第一和第二阀部分是 放置在阀室(36)中并以彼此相反的方式进行打开和关闭操作; 以及用于使阀体(40)移动的螺线管(60)。 阀体(40)在其端部处具有与第一阀部(41)相对的第二阀部(42)的压力接收部(44),受压部(44)承受控制中的压力 室。 受压部(44)的受压面积S3与第二阀部(42)的受压面积S2与第一阀部的受压面积S1的差大致相同。 阀的尺寸减小,控制室内的压力的影响最小化,能够实现稳定的容量控制。
