    • PURPOSE: A control valve for a variable capacity compressor is provided to minimize hysteresis for a valve open-and-close motion even if the straight-forward performance of a bellows is not good and to increase the accuracy of the valve open-and-close motion. CONSTITUTION: A control valve(10) for a variable capacity compressor has a bellows body(27) projected and supported in a bellows case(13) of a closed structure by a pressure sensing element and changes the opening degree of a valve by transmitting the expansion and contraction of the bellows body generated according to the change of suction pressure(Ps) of the compressor to a valve body(21) through a valve bar(25) for moving a valve housing(11) integrated with the bellows case to the valve-lifting direction. An immersing member(31) is installed at a movable end of the bellows body. A fitting recessed unit(31b) is formed at the immersing member. The valve bar is movably fitted to the fitting recessed unit. A compression coil spring(24,30) is mounted between the immersing member and a lower immersing member(28) for supporting a non-movable end of the bellows body.
    • 目的:提供用于可变容量压缩机的控制阀,以尽可能减少阀门开启和关闭运动的滞后,即使波纹管的直接性能不好,并提高阀门开启和关闭的精度 运动。 构成:用于可变容量压缩机的控制阀(10)具有通过压力传感元件突出并支撑在封闭结构的波纹管壳体(13)中的波纹管体(27),并且通过传递阀 根据压缩机的吸入压力(Ps)变化通过阀杆(25)产生的波纹管体的膨胀和收缩,用于将与波纹管壳体一体化的阀壳体(11)移动到阀体 提升方向。 浸入构件(31)安装在波纹管体的可动端。 在浸渍构件上形成嵌合凹部(31b)。 阀杆可移动地装配到配件凹陷单元。 压缩螺旋弹簧(24,30)安装在浸渍构件和用于支撑波纹管主体的不可移动端的下浸渍构件(28)之间。
