液压元件可分为动力元件和控制元件以及执行元件三大类。尽管都是液压元件，它们的自身功能和安装使用的技术要求也不尽相同，现分别介绍如下：
动力元件：指的是各种液压泵，齿轮泵、叶片泵、柱塞泵、螺杆泵。
1、齿轮油泵和串联泵（包括外啮合与内啮合）两种结构型式。
2、叶片油泵（包括单级泵、变量泵、双级泵、双联泵）。
3、柱塞油泵，又分为轴向柱塞油泵和径向柱塞油泵，轴向柱塞泵有定量泵、变量泵、（变量泵又分为手动变量与压力补偿变量、伺服变量等多种）从结构上又分为端面配油和阀式配油两种配油方式，而径向柱塞泵的配油型式，基本上为阀式配油。）；
执行元件：液压缸和液压马达，液压缸有活塞液压缸、柱塞液压缸、摆动液压缸、组合液压缸；液压马达有齿轮式液压马达、叶片液压马达、柱塞液压马达；

力士乐电磁溢流阀
溢流阀是一种液压压力控制阀。在液压设备中主要起定压溢流作用，稳压，系统卸荷和安全保护作用。 定压溢流作用：在定量泵节流调节系统中，定量泵提供的是恒定流量。当系统压力增大时，会使流量需求减小。此时溢流阀开启，使多余流量溢回油箱，保证溢流阀进口压力，即泵出口压力恒定（阀口常随压力波动开启）。
稳压作用：溢流阀串联在回油路上，溢流阀产生背压运动部件平稳性增加。
系统卸荷作用：在溢流阀的遥控口串接溢小流量的电磁阀，当电磁铁通电时，溢流阀的遥控口通油箱，此时液压泵卸荷。溢流阀此时作为卸荷阀使用。
安全保护作用：系统正常工作时，阀门关闭。只有负载超过规定的极限（系统压力超过调定压力）时开启溢流，进行过载保护，使系统压力不再增加（通常使溢流阀的调定压力比系统最高工作压力高10%～20%）。
实际应用中一般有：作卸荷阀用，作远程调压阀，作高低压多级控制阀，作顺序阀，用于产生背压（串在回油路上）。
溢流阀一般有两种结构：1、直动型溢流阀 。2、先导型溢流阀。
对溢流阀的主要要求：调压范围大，调压偏差小，压力振摆小，动作灵敏，过载能力大，噪声小。

阀对流量的控制可以分为两种：
一种是开关控制：要么全开、要么全关，流量要么最大、要么最小，没有中间状态，如普通的电磁直通阀、电磁换向阀、电液换向阀。
另一种是连续控制：阀口可以根据需要打开任意一个开度，由此控制通过流量的大小，这类阀有手动控制的，如节流阀，也有电控的，如比例阀、伺服阀。
所以使用比例阀或伺服阀的目的就是：以电控方式实现对流量的节流控制（当然经过结构上的改动也可实现压力控制等），既然是节流控制，就必然有能量损失，伺服阀和其它阀不同的是，它的能量损失更大一些，因为它需要一定的流量来维持前置级控制油路的工作。
