充液阀是一种特殊的液控单向阀，一个方向止流，另一个方向自由流通，先导动作是由油口供压的控制阀芯用液压实现的，由此而直接打开主阀。这种阀为叠加系统而设计，即在一个基础件上，可以叠加各种各样的其它类别液压阀。其主要作用是从油箱（或充液油箱）向液压缸或者系统补充油液，以免出现吸空现象。带控制的充液阀还能起快速排油的作用。
2.2充液阀的典型结构
充液阀有常闭式和常开式两种典型结构
。
(1)常闭式充液阀
常闭式充液阀有不可控式和可控式两种形式，不可控式充液阀，它是由阀芯、导向套、复位弹簧、阀体和连接法兰等主要零件组成。阀芯是蘑菇形的，结构较紧凑，流阻损失小；阀芯重量轻惯性小，动作灵敏。
对于可控式充液阀。控制油通入控制缸的上腔，控制活塞就可使阀芯开启。控制缸上腔接油箱时，控制活塞在弹簧的作用下复位。控制缸下腔与充液油箱是想通的。这两种结构的充液阀都直接安装在液压缸的端部，安装方便，节省了与工作液压缸连接的管道。浸入式结构，即上部全浸在充液油箱中，结构很紧凑，流阻损失很小。但充液油箱必须安装在液压缸的底部，还要解决充液油箱与液压缸缸底之间的密封问题。检修不太方便。管道连接式结构，即通过管道和法兰与充液油箱相连，与浸入式相比，充液油箱的位置布置较灵活，检修也较方便，但结构显得庞大，流阻损失也稍大。

常开式充液阀的优点在于充液过程中不需要克服弹簧力，从而减少了吸油阻力。但结构较复杂，制造要求也较高。
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，液压缸先行卸压，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。

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。
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，逐渐降低主阀开度，P与O口间的节流作用造成P口压力增高。随后P口与A口间的单向阀打开，经节流口向蓄能器供液。当蓄能器压力达到上限时，作用在先导阀右端单向阀阀芯3的液压力大于左端弹簧压力，下限单向阀6打开，上限单向阀3关闭，主阀右腔经先导阀于T口相通泄压，在左端压力作用下克服右端弹簧压力右移，P口与A口间的单向阀关闭，恢复全流量向下游系统供液，充液过程结束。
