    • A high pressure metering valve has a valve element with a closing portion, a metering portion and a rapid return portion. The closing portion seats against a corner seat at the end of a valve bore in which the metering portion has a close sliding fit. When the element is unseated, a flow rate can be metered depending on the overlapping length of the metering portion in the valve bore. At the opposite end of the metering portion, the rapid return portion is undercut to be of smaller area than the metering portion to provide a full open state for rapid fluid return.
    • 高压计量阀具有带有关闭部分,计量部分和快速返回部分的阀元件。 关闭部分在阀孔的端部抵靠角座,其中计量部分具有紧密的滑动配合。 当元件离开时,可以根据阀孔中的计量部分的重叠长度来计量流量。 在计量部分的相对端,快速返回部分被底切以具有比计量部分更小的面积,以提供完全打开状态以快速流体返回。

    • A high accuracy medical trailer leveling system capable of detecting at least three level orientations including level along a longitudinal direction, level along a lateral direction at the front of the trailer, and level along a lateral direction at the rear of the trailer. The system also includes sensors that detect a level orientation in the longitudinal direction at the front of the trailer and a level orientation in the longitudinal direction at the rear of the trailer. A touch pad has buttons for controlling the system and a display screen, the display screen being capable of displaying a level condition in a particular location of the trailer and direction. The display screen can display the level orientation of side to side, front; side to side, rear; and front to back, and can also display the angle of inclination. One set of lights on the control pad indicates which jacks to actuate to level the vehicle, and another set of lights indicates which jacks are being actuated.
    • 一种高精度医疗拖车整平系统,其能够检测至少三个水平方向,包括沿着纵向方向的水平,沿着拖车前部的横向方向的水平,以及在拖车后部沿着横向的水平。 该系统还包括在拖车前部检测纵向方向上的水平方向的传感器,以及拖车后部沿纵向方向的水平方向。 触摸板具有用于控制系统和显示屏幕的按钮,显示屏能够在拖车的特定位置和方向上显示电平状况。 显示屏可以显示一侧到另一边的水平方向; 一边到另一边 并且从前到后,还可以显示倾斜角度。 控制盘上的一组指示灯指示哪个插孔启动以使车辆平整,另一组指示灯指示哪个插孔正在被致动。
