REXROTH柱塞泵往复运动的总行程L是常数，由凸轮的升程决定。柱塞每个循环的供油量不受凸轮轴控制，取决于可变供油行程。供油行程的变化不会改变供油开始时间。当柱塞转动时，加油结束时间发生变化，加油量发生变化。当REXROTH柱塞泵启动时，喷油泵的凸轮轴凸轮和柱塞弹簧作用，使柱塞上下往复运动，完成抽油任务。

REXROTH柱塞泵有两个方向相反的止回阀。当柱塞向一个方向移动时，在气缸中产生负压并完成一项压缩后阀门打开。当液体被吸入气缸，柱塞向相反方向移动时，液体被压缩后另一个单向阀打开，吸入气缸的液体被排出。在这种工作方式下连续运动后，形成连续供油。

柱塞泵有两个单向的阀门，且呈相反的方向；是属于液压系统的重要装置，工作的原理是依靠柱塞在缸体进行的往复运动，使泵在密封工作时容腔里的容积产生变化，来完成吸油、压油的过程，依靠泵轴的偏心转动驱动，进而实现往复运动过程；当柱塞向外运动时，缸内会呈现负压状态，与之同时其中的一个单向阀门打开，液体被吸入缸内；当柱塞向内运动，合上时缸内压力增强，此时另一个单向阀门打开，吸入缸内的液体排出；泵轴的偏心转动不停的驱动柱塞内外往复，达到完成吸油和排油的目的，这个过程有点像儿时玩过的注射器，只是注射器进出都是一个阀口，柱塞泵将其分开，原理很相似，非常好理解。

rexroth油泵是液压系统的动力机构，它将原动机（电动机、内燃机等）的机械能转变为液体的压力能。力士乐油泵可以分为容积式和非容积室（蜗轮式）两种。非容积式有离心泵、轴流泵等，利用高

速旋转的叶轮使进口产生真空吸入液体，并在出口连续输出压力液体。这种泵进口与出口相通，效率随液体粘度增加而降低，并且输出液体量随出口压力升高而减少。
