    • A power steering apparatus having a fluid source for discharging pressurized fluid, a power cylinder, a control valve responsive to operation of a steering wheel for supplying the power cylinder with pressurized fluid from the fluid source, and a reservoir. The control valve has a first control portion for controlling the flow of pressurized fluid from the fluid source to the reservoir, and a second control portion for controlling the flow of pressurized fluid to the power cylinder. The first control portion has two paths connecting the fluid source and the reservoir, each of the paths being formed with at least one variable orifice of a center-open type which opens when the control valve is in a neutral state. The second control portion has two supply paths communicating with the fluid source and a pair of chambers of the power cylinder, each of the supply paths being formed with a variable orifice of a center-close type which closes when the control valve is in the neutral state, and two drain paths communicating with the pair of chambers and the reservoir, each of the drain paths being formed with a variable orifice of a center-open type which opens when the control valve is in the neutral state.

    • A power steering apparatus for turning a steerable wheel of a vehicle in response to steering operation by a driver. The apparatus comprises a hydraulic pump for pumping a fluid from a reservoir so as to supply pressurized fluid to a power cylinder formed in a gear housing through a direction control valve which is operable in response to rotation of the steering wheel for selectively delivering the pressurized fluid to pair of pressure chambers of the power cylinder. The apparatus further comprises an electric motor for rotating the hydraulic pump, an accumulator for accumulating the pressurized fluid discharged from the hydraulic pump, a detector for detecting the pressure of the pressurized fluid and for outputting a signal corresponding to the detected pressure, and a controller responsible to the signal from the detector for activating the electric motor only when the detected pressure is below a predetermined level. The hydraulic pump and the electric motor are mounted on the gear housing.

    • A solenoid-operated valve particularly for use in a speed-responsive power steering system on a motor vehicle comprises a valve housing having two ports opening into a bore in the housing, a spool axially slidable in the bore and slot defining a bypass passageway extending between the two ports and variable in cross section upon axial movement of the spool. The spool is spring-biased in a direction to close the bypass passageway, but attractable by an energized solenoid to open the bypass passageway when the solenoid is supplied with an electric current dependent on the speed of travel of the vehicle. The spool has therein a restrictor disposed in the bypass passageway adjacent to the slot to restrict the flow of a fluid through the bypass passageway into and out of the bore in the housing. The restrictor develops a pressure drop while the fluid flows through the bypass passageway to maintain the spool substantially in equilibrium while the fluid under pressure flows through the bypass passageway in either direction upon axial shifting of the spool. The solenoid-operated valve enables dirigible wheels to be assisted in getting turned to the right or left by equal or balanced steering forces generated by the power steering system.
    • 特别用于机动车辆上的速度响应型动力转向系统的电磁操作阀包括具有通向壳体中的孔的两个端口的阀壳体,可在该孔和轴中可轴向滑动的阀芯,该阀芯限定了在 两个端口并且在阀芯的轴向运动时横截面可变。 阀芯沿一个关闭旁路通道的方向被弹簧偏压,但是当螺线管被提供有取决于车辆行进速度的电流时,通过通电螺线管可以吸引旁路通道。 该卷轴在其中具有限制器,其设置在邻近狭槽的旁路通道中,以限制流体通过旁通通道流入和流出壳体中的孔的流动。 限流器在液体流过旁路通道时产生压力降,以保持阀芯基本处于平衡状态,同时压力流体在阀芯轴向移动时沿任一方向流过旁路通道。 电磁阀通过动力转向系统产生的相等或平衡的转向力,使得可拆卸的车轮能够被辅助向右或向左转。
