REXROTH軸向柱塞泵，泵體結構分析
德國REXROTH力士樂直軸斜盤式柱塞泵：
直軸斜盤式柱塞泵分為壓力供油型和自吸油型兩種。壓力供油型液壓泵大都是采用有氣壓的油箱，靠氣壓供油的液壓油箱，在每次啟動機器之后，必須等液壓漬箱達到使用氣壓后，才能操作機械。如液壓油箱的氣壓不足時就啟動機器，會對液壓泵內的與滑靴造成拉脫現象，出會造成泵體內回程板與壓板的非正常磨損。
REXROTH力士樂徑向式柱塞泵：
徑向柱塞泵可分為閥配流與軸配流兩大類。閥配流徑向柱塞泵存在故障率高、效率低等缺點。上70、80年代發展的軸配流徑向柱塞泵克服了閥配流徑向柱塞泵的不足。由于徑向泵結構上的特點，固定了軸配流徑向柱塞泵比軸向柱塞泵耐沖擊、壽命長、控制精度高。變量行程短泵的變量是在變量柱塞和限位柱塞作用下，改變定子的偏心距實現的，而定于的zui大偏心距為 5—9mm（根據排量大小不同），變量行程很短。且變量機構設計為高壓操縱，由控制閥進行控制。故該泵的響應速度快。徑向結構設計克服了如軸向柱塞泵滑靴偏磨的問題。使其抗沖擊能力大幅度提高。
