    • A pressure control valve for adjusting a controlled pressure supplied to an actuator includes first and second valves. The first valve serves to modify a pressure level of a working fluid supplied from a fluid pressure source to a preselected level and provides it to the actuator. The second valve is responsive to a control signal commanding elevation or reduction in the controlled pressure from a controller to adjust a supply pressure level from the fluid pressure source to provide a pilot pressure, elevated or reduced to a preselected level, to the first valve for activating same. When elevating or reducing the pilot pressure, the second valve decreases the supply pressure level from the fluid pressure source by a preselected degree, for balancing a flow gain when elevating the pilot pressure with that when reducing the pilot pressure, for providing uniform response for elevation and reduction of the controlled pressure to the actuator.
    • 用于调节供应到致动器的受控压力的压力控制阀包括第一和第二阀。 第一阀用于将从流体压力源供应的工作流体的压力水平改变为预选的水平并将其提供给致动器。 第二阀响应于控制信号,其控制来自控制器的控制压力的升高或降低,以调节来自流体压力源的供应压力水平,以向第一阀提供升高或降低到预选水位的先导压力 激活相同。 当提升或降低先导压力时,第二阀将预先设定的流量压力源的供给压力水平降低,以便在降低先导压力时降低先导压力时的流量增益的平衡,以提供均匀的升程响应 并且减小对致动器的受控压力。

    • A torque is transmitted between a fluid pressure pump driven together with drive of a vehicle, and a fluid pressure motor that rotates together with driven wheels. The fluid pressure motor has two ports, and rotates in accordance with the direction of fluid supply to the ports. Fluid is circulated from one port to the other according to the input of rotation torque from the driven wheels. A high pressure flowpath connected to the pump outlet, and a low pressure flowpath connected to the pump inlet, are connected to these ports, and the connection direction is reversed when the rotation direction of the drive wheels is reversed. The low pressure flowpath is therefore always at low pressure regardless of the rotation direction of the drive wheels, and by controlling the pump supply flowrate so as not to exceed a predetermined value, torque is not transmitted when the vehicle is running at high speed.
    • 在与车辆的驱动一起驱动的流体压力泵和与驱动轮一起旋转的流体压力马达之间传递扭矩。 流体压力马达具有两个端口,并且根据向端口的流体供应方向旋转。 根据来自驱动轮的旋转扭矩的输入,流体从一个端口循环到另一个端口。 连接到泵出口的高压流路和连接到泵入口的低压流动路径连接到这些端口,并且当驱动轮的旋转方向相反时连接方向相反。 因此,低压流动路径总是处于低压,而与驱动轮的旋转方向无关,并且通过将泵供给流量控制为不超过预定值,当车辆高速行驶时,不传递转矩。
