    • A fluid flow control valve which has a pair of solenoids that move a hollow ball valve between a first position and a second position. When the ball valve is in the first position, fluid is allowed to flow from an inlet port to a cylinder port. When the ball valve is in the second position, fluid is allowed to flow from the cylinder port to a drain port. The ball valve sits against one of two valve seats which are constructed from steel and a have radial shape that conforms to the shape of the ball. The hystersis of the steel maintains the ball valve in one of the two positions, so that power does not have to be continuously provided to the solenoids. The ball valve has a hollow inner chamber which significantly reduces the weight of the ball and increases the response rate of the control valve.
    • 一种流体流量控制阀,其具有使中空球阀在第一位置和第二位置之间移动的一对螺线管。 当球阀处于第一位置时,允许流体从入口流到气缸端口。 当球阀处于第二位置时,允许流体从气缸端口流到排放口。 球阀位于由钢构成的两个阀座中的一个上,并具有符合球形的径向形状。 钢的滞后将球阀保持在两个位置中的一个位置,使得电源不必连续地提供给螺线管。 球阀具有中空的内腔,其显着地减小了球的重量并增加了控制阀的响应速度。

    • A three position digitally latched actuator actuated fluid control valve. The control valve includes a housing which has a cylinder port, a supply port and a return port. The control valve also contains an internal valve that moves between a first position, a second position and a neutral position. In the first position the internal valve provides fluid communication between the cylinder port and the supply port. In the second position the valve provides fluid communication between the cylinder port and the return port. In the neutral position the valve prevents fluid communication between the ports. The control valve has a first actuator and a second actuator that are actuated by digital pulses to move the internal valve between the first, second and neutral positions. The control valve may have a pair of springs that bias the internal valve to the neutral position, wherein the actuator can be actuated to latch the valve into the first position and the second actuator can be actuated to latch the valve into the second position.
    • 三位数字锁定致动器致动流体控制阀。 控制阀包括具有气缸端口,供给口和返回口的壳体。 控制阀还包含内部阀,其在第一位置,第二位置和中间位置之间移动。 在第一位置,内部阀提供气缸端口和供给口之间的流体连通。 在第二位置,阀提供气缸端口和返回端口之间的流体连通。 在中立位置,阀阻止端口之间的流体连通。 控制阀具有由数字脉冲致动的第一致动器和第二致动器,以在第一,第二和中性位置之间移动内部阀。 控制阀可以具有将内部阀偏压到中立位置的一对弹簧,其中可以致动器致动以将阀锁定到第一位置,并且可以致动第二致动器以将阀闩锁到第二位置。
