    • The invention concerns a hydraulic valve arrangement (1) with a supply connection arrangement comprising a high-pressure connection (P) and a low-pressure connection (T), a working connection arrangement comprising two working connections (A, B), which can be connected to a motor (4), a directional valve arrangement (5) located between the supply connection arrangement (P, T) and the working connection arrangement (A, B), and a compensation valve (15) acted upon in a first activation direction by a pressure in a first pressure chamber (33), which is connected to a load-sensing pipe (LS), and, if required, by a spring (32), and in a second activation direction opposite to the first activation direction by a pressure downstream of the directional valve arrangement (5), said pressure acting in a second pressure chamber (34), the compensation valve (15) having an inlet (14) and an outlet (19). In connection with a post-compensated valve, it is endeavoured to adjust the load pressures at the working connections (A, B) in dependence of the direction. For this purpose, each working connection (A, B) is connected to a control system, which amplifies the effect of the pressure in the first pressure chamber (33) on the compensation valve (15) in dependence of a pressure ruling at the working connection (A, B).
    • 本发明涉及具有包括高压连接(P)和低压连接(T)的供应连接装置的液压阀装置(1),包括两个工作连接(A,B)的工作连接装置,其可以 连接到电动机(4),位于供应连接装置(P,T)和工作连接装置(A,B)之间的方向阀装置(5)和补偿阀(15) 通过连接到负载传感管(LS)的第一压力室(33)中的压力,以及如果需要,通过弹簧(32)和在与第一激活相反的第二激活方向上的压力的激活方向 方向阀装置(5)下游的压力,所述压力作用在第二压力室(34)中,补偿阀(15)具有入口(14)和出口(19)。 结合补偿后阀门,努力根据方向调整工作连接(A,B)的负载压力。 为此,每个工作连接(A,B)连接到控制系统,该控制系统根据工作中的压力判定放大第一压力室(33)中的压力对补偿阀(15)的影响 连接(A,B)。

    • The invention relates to a steering control unit for a bidirectional servomotor which is connectable to steerable wheels. A steering wheel controlled quantity setting unit of a known type has ports connectable to a pump and a return tank and two control ports through which metered quantities of fluid flow to opposite sides of the servomotor and to other parts of the apparatus for actuating the servomotor. A directional control valve for selectivity directing pressurized fluid from a power circuit to opposite sides of the servomotor is controlled by a control circuit containing the setting unit. A utility valve having pressure regulating and control and power valve capabilities is provided. In cases wherein the quantity setting apparatus is remotely located from the regulating valve the length of the signal channels add to the reaction time. Such reaction time is reduced herein by connecting the metering throttle as a fixed throttle between the regulating valve and quantity setting apparatus so that the regulating valve feeds a substantially constant quantity to the control cicuit, and that the quantity setting apparatus comprises a short circuit path to the tank which closes with an increase in the quantity.
    • 本发明涉及一种用于双向伺服电机的转向控制单元,其可连接到可转向的车轮。 已知类型的方向盘控制量设定单元具有可连接到泵和回流罐的端口和两个控制端口,计量量的流体流过伺服电机的相对侧以及用于致动伺服电动机的装置的其它部分。 用于将加压流体从功率电路选择性地引导到伺服电动机的相对侧的方向控制阀由包含设定单元的控制电路控制。 本发明提供一种具有压力调节和功率阀功能的电力阀。 在数量设定装置远离调节阀的情况下,信号通道的长度增加到反应时间。 这样的反应时间通过将调节阀和量设定装置之间的固定节流阀连接在一起,使得调节阀向控制电路供给基本上恒定的量,并且量设定装置包括短路路径 随着数量的增加关闭的油箱。
