常开式充液阀。阀芯在弹簧的作用下停在阀上部，充液阀处于开启状态。当转入工作行程时，先在充液阀的控制口通入压力油，阀芯下行，充液阀关闭。由于阀芯上部面积略大于其下部面积，故随着液压缸油压的升高，充液阀越关越紧。当活塞回程时，液压缸***卸压，且充液阀的控制口与油箱相通，充液阀可自动开启，使液压缸中的油液大量排回充液油箱。R900306453 M-SR102KD15-1X/V

2.3 充液阀的结构原理
图2.1为单回路充液阀的结构，主要由控制充液压力上下限的先导阀和充液主阀构成，图中的P、O、A、T分别为油泵压力油进油口、通往下游液压系统的出口、通往蓄能器出口及回油口。力士乐电液换向阀4WEH22J7X/6EG24N9ETS2K4/V

充液阀的充液过程为:当蓄能器的压力低于充液阀设定的下限压力时，作用在上限单向阀阀芯3上的液压力低于先导阀4左端弹簧8的作用力，使下限单向阀6关闭，上限单向阀3打开，蓄能器内的压力油经先导阀芯4、节流通道Ⅱ进入主阀右腔，推动主阀芯9克服左腔压力向左移动0811405073 VT-VRPA 1-527-20/V0/RTS-2STV
