电液比例阀简称比例阀。普通液压阀只能通过预调的方式对液流的压力、流量进行定值控制。但是当设备机构在工作过程中要求对液压系统的压力、流量参数进行调节或连续控制，例如.要求工作台在工作进给时按慢、快、慢连续变化的速度实现进给，或按一定精度模拟某个最佳控制曲线实现旅力控制.普通液压阀则实现不了。这时可以用电液比例阀对液压系统进行控制。
电液比例阀是一种按输入的电信号连续地、按比例地控制液压系统的液流方向、流量和压力的阀类。它山电-机械比例转换装置和液压控制阀本体两大部分构成.前者将输入的电信号连续地按比例地转换为机械力和位移输出，后者在接受这种机械力和位移之后、按比例连续地输出压力和流量.
电液比例阀的发展主要有两个途径一是用比例电磁铁取代传统液压阀的手动调节装置或取代普通电磁铁发展起来的;二是由电液伺服阀简化结构、降低精度发展起来的。下面介绍的比例阀均指前者，它是当今比例阀的主流。与普通液压阀可以互换。
比例电磁阀的结构如图5-27所示。比例电磁铁是直流电磁铁，但它与普通直流电磁铁不同。普通直流电磁铁的衔铁只有吸合和断开两个工作位置，并且在吸合时磁路中几乎没有气隙.而比例电磁铁要求吸合力或位移与给定电流成比例。并在衔铁的全部工作行程上，磁路中保持一定的气隙‘.其结构主要由极靴1、线圈2、壳体5和衔铁10等组成。线圈2中通电后产生磁场，因隔磁环4的存在。使磁力线主要部分通过衔铁10、气隙和极靴1，形成回路口极靴对衔铁产生吸力门在线圈中电流一定时。吸力的大小因极靴1与衔铁间的距离不同而变化。但衔铁在气隙适中的一段行程中，吸力随位置的改变发生的变化很小。
设计中就使比例电磁铁的衔铁在这段行程中工作。因此。改变线圈中的电流，即可在衔铁上得到与其成正比的吸力。用比例电磁铁代替螺旋手柄来调整液压阀，就能使输出乐力或流量与输人电流对应成比例地发生变化。
比例阀用于模拟控制，是介于普通开关控制与伺服控制之间的控制方式，它也特别适合于
设备的革新或改造。使设备自动化控制水平大为提高。其在现代液雌系统中占比例很大口
与普通液压阀相比.比例阀的优点是:①能简单地实现远距离控制:②能连续地、按比例地控制液压系统的压力和流量。从而实现对执行机构的位置、速度和力的连续控制，并能防止或减小压力、速度变换时的冲击;③油路简化，元件数量少。
比例阀适用于既要求能连续控制胀力、流量.和方向.而又不需要很I的控制精度的场合。
比例阀也分为压力阀、流量阀和方向阀几大类。近来又出现了功能复合化的趋势。

结构组成主要有偏心轮、柱塞、弹簧、缸体、两个单向阀。柱塞与缸体孔之间形成密闭容积。偏心轮旋转一转，柱塞上下往复运动一次，向下运动吸油，向上运动排油。泵每转一转排出的油液体积称为排量，排量只与泵的结构参数有关。
柱塞泵是由几个柱塞（一般为3个或6个）并列安装，用1根曲轴通过连杆滑块或由偏心轴直接推动柱塞做往复运动，实现吸、排液体的液压泵。它们也都采用阀式配流装置，而且大多为定量泵。煤矿液压支架系统中的乳化液泵一般都是卧式柱塞泵。AA10VSO45DFR1/31R-VPA12KB3

是活塞或柱塞的往复运动方向与缸体中心轴平行的柱塞泵。轴向柱塞泵利用与传动轴平行的柱塞在柱塞孔内往复运动所产生的容积变化来进行工作的。由于柱塞和柱塞孔都是圆形零件，加工时可以达到很高的精度配合，因此容积效率高
