    • A regulator valve is structured such that hydraulic pressure to be output from a regulated pressure output port is regulated according to urging forces, i.e., line pressure to be regulated, throttle pressure, spring force from a compression coil spring, and operating force from a plunger, which are applied to a valve spool. The plunger has a small diameter portion and a large diameter portion having a diameter larger than the diameter of the small diameter portion, both of which are axially displaceably retained in a spring receiving sleeve. The small diameter portion is urged in one axial direction at one end of the plunger that protrudes into a spring chamber and faces the valve spool, while the large diameter portion is urged in the other axial direction by range pressure at the other end of the plunger which is isolated from the small diameter portion located in the spring chamber.
    • 调节阀被构造成使得从调节压力输出端口输出的液压根据作用力调节,即被调节的管路压力,节流阀压力,来自压缩螺旋弹簧的弹簧力,以及来自柱塞的操作力 ,其被施加到阀芯。 柱塞具有小直径部分和大直径部分,其直径大于小直径部分的直径,两者均轴向移位地保持在弹簧接收套筒中。 小直径部分在柱塞的一端沿一个轴向方向被推压到弹簧室中并面向阀芯,而大直径部分在另一个轴向方向上被推压在柱塞另一端的范围压力 其与位于弹簧室中的小直径部分隔离。

    • In a hydraulic control apparatus for a vehicle automatic transmission, a check valve is provided parallel to a first oil passageway switching valve and a third oil passageway switching valve between an output port of a linear solenoid valve and a brake, and the check valve permits pressure oil to flow from the brake to the output port side, and blocks the flow thereof in the opposite direction. Therefore, the pressure oil from the brake when the brake is released is supplied to the output port via the check valve, not via the first or third oil passageway switching valve. Therefore, when the brake is released, the engaging pressure of the brake can be controlled by the linear solenoid valve, and the positions of the first and third oil passageway switching valves are not restricted.
    • 在用于车辆自动变速器的液压控制装置中,在线性电磁阀的输出口和制动器之间平行于第一油路切换阀和第三油路切换阀设置止回阀,并且止回阀允许压力 油从制动器流向输出口侧,并阻止其沿相反方向的流动。 因此,当制动器被释放时来自制动器的压力油经由止回阀而不是通过第一或第三油路切换阀被供给到输出口。 因此,当制动器被释放时,制动器的接合压力可以由线性电磁阀控制,并且第一和第三油路切换阀的位置不受限制。
