REXROTH轴向柱塞泵，泵体结构分析
德国REXROTH力士乐直轴斜盘式柱塞泵：
直轴斜盘式柱塞泵分为压力供油型和自吸油型两种。压力供油型液压泵大都是采用有气压的油箱，靠气压供油的液压油箱，在每次启动机器之后，必须等液压渍箱达到使用气压后，才能操作机械。如液压油箱的气压不足时就启动机器，会对液压泵内的与滑靴造成拉脱现象，出会造成泵体内回程板与压板的非正常磨损。
REXROTH力士乐径向式柱塞泵：
径向柱塞泵可分为阀配流与轴配流两大类。阀配流径向柱塞泵存在故障率高、效率低等缺点。上70、80年代发展的轴配流径向柱塞泵克服了阀配流径向柱塞泵的不足。由于径向泵结构上的特点，固定了轴配流径向柱塞泵比轴向柱塞泵耐冲击、寿命长、控制精度高。变量行程短泵的变量是在变量柱塞和限位柱塞作用下，改变定子的偏心距实现的，而定于的zui大偏心距为 5—9mm（根据排量大小不同），变量行程很短。且变量机构设计为高压操纵，由控制阀进行控制。故该泵的响应速度快。径向结构设计克服了如轴向柱塞泵滑靴偏磨的问题。使其抗冲击能力大幅度提高。
