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。 AGAM-10/11/350-IX 230/50/60AC 34

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。DPHI-3713/D-X 53,　DPHI-3713/E-X ,　DPHI-3713/H-X 53,

(2)常开式充液阀
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。
