    • A rotor balancing arrangement is provided for use in a distribution valve to ensure hydrostatic balancing of a rotor located in the distribution valve. Some balancing arrangements provide areas equally spaced around the peripheral surface, each being exposed to the same pressure, however, they are limited to valves which rotate only through a limited arc of rotation. Other valves which rotate provide balancing grooves around portions of the peripheral surface but do not provide any control for the pressure that migrates axially in both directions along the peripheral surface of the rotor. In the subject arrangement, pressure fields of a predetermined size are located on a peripheral surface of a rotor circumscribing first and second outlet ports which open to opposite sides of the rotor. The size of the pressure fields is determined by the relationship of the diametrical clearance between the rotor and a bore with respect to the operating pressure of the system. This arrangement ensures that the differential forces acting on opposite sides of the rotor are minimized thus eliminating rotor sticking.
    • 提供了用于分配阀中的转子平衡装置,以确保位于分配阀中的转子的静水平衡。 一些平衡装置提供围绕周边表面等间隔的区域,每个区域暴露在相同的压力下,然而,它们仅限于仅通过有限的旋转旋转旋转的阀。 旋转的其它阀提供围绕周边表面的部分的平衡槽,但是不对沿着转子的外周表面沿两个方向轴向移动的压力提供任何控制。 在主题布置中,预定尺寸的压力场位于限定转子相对侧的第一和第二出口的转子的外周表面上。 压力场的尺寸由转子和孔之间的直径间隙相对于系统的操作压力的关系确定。 这种布置确保了作用在转子相对侧上的差动力最小化从而消除了转子的粘附。

    • A fuel injector assembly for a fuel injection system has a fuel pumping assembly with a fuel inlet and a fuel nozzle for causing fuel to be periodically pumped from the fuel inlet through the nozzle. The fuel injector assembly has an electro-hydraulic control valve associated with the fuel pumping means. The control valve comprises a housing, a first conduit formed in the housing and fluidly coupled to the fuel pumping means, a second conduit formed in the housing and fluidly coupled to a source of pressurized hydraulic fluid. A valve element is disposed in the housing and is reciprocable between a first position in which the first conduit is fluidly coupled to the second conduit and a second position in which the first conduit is fluidly isolated from the second conduit. The control valve also includes a pair of electrically energizable electromagnetic devices for controlling the reciprocation of the valve element. The components of the control valve are preferably composed of SAE 52100 steel so that the valve element remains latched in the first and second positions after electric current to the electromagnetic devices is turned off.
    • 用于燃料喷射系统的燃料喷射器组件具有燃料泵送组件,其具有燃料入口和燃料喷嘴,用于使燃料周期性地从燃料入口通过喷嘴泵送。 燃料喷射器组件具有与燃料泵送装置相关联的电液控制阀。 控制阀包括壳体,形成在壳体中并流体耦合到燃料泵送装置的第一导管,形成在壳体中并流体耦合到加压液压流体源的第二导管。 阀元件设置在壳体中并且可在其中第一管道流体地联接到第二管道的第一位置和第二管道与第二管道流体隔离的第二位置之间往复运动。 控制阀还包括一对用于控制阀元件的往复运动的电激励电磁装置。 控制阀的部件优选地由SAE 52100钢组成,使得在电磁装置的电流被关闭之后阀元件在第一和第二位置保持锁定。
