    • An end-of-fill detection arrangement is provided in a power distribution system to detect when a clutch is fully filled and the pressure therein can be progressively increased to full engagement. The arrangement includes placing a position sensor in a pressure relief valve that is controlling the desired pressure level to respective clutches and directing the sensed position of the valving element therein to an electronic controller. The controller monitors the position of the valving element in the relief valve. Initiation of filling of a clutch results in the valving element moving from a bypassing position towards a flow blocking position. This movement is noted by the controller and when the valving element returns generally to its initial location, the clutch is filled. The controller notes the end-of-fill and provides a command signal to the proportional valve to progressively increase the pressure in the clutch until the clutch is fully engaged. The subject invention provides a simple arrangement that detects the end-of-fill.
    • 在配电系统中提供了一种填充后检测装置,用于检测离合器何时完全充满,并且其中的压力可以逐渐增加到完全接合。 该装置包括将位置传感器放置在压力释放阀中,该压力释放阀将所需的压力水平控制到相应的离合器,并将其中的阀元件的感测位置引导到电子控制器。 控制器监控溢流阀中阀元件的位置。 开始填充离合器导致阀元件从旁路位置朝向阻流位置移动。 该运动由控制器注意到,并且当阀元件大体上返回到其初始位置时,离合器被填充。 控制器注意到填充结束,并向比例阀提供命令信号,以逐渐增加离合器中的压力,直到离合器完全啮合。 本发明提供了检测填充结束的简单布置。
