德國力士樂REXROTH柱塞泵是液壓系統的一個重要裝置。它依靠柱塞在缸體中往復運動，使密封工作容腔的容積發生變化來實現吸油、壓油。柱塞泵具有額定壓力高、結構緊湊、效率高和流量調節方便等優點。柱塞泵被廣泛應用于高壓、大流量和流量需要調節的場合，諸如液壓機、工程機械和船舶中。
力士樂REXROTH柱塞泵結構形式：
柱塞泵分為兩種有代表性的結構形式的軸向柱塞泵和徑向柱塞泵；由于徑向柱塞泵屬于一種新型的技術含量比較高的高效泵，隨著國產化的不斷加快，徑向柱塞泵必然會成為柱塞泵應用領域的重要組成部分；徑向柱塞泵是活塞或柱塞的往復運動方向與驅動軸垂直的柱塞泵。徑向柱塞泵工作原理:驅動扭矩由驅動軸 通過十字聯軸器 傳遞給星形的液壓缸體轉子，定子不受其它橫向作用力。轉子裝在配流軸上。位于轉子中的徑向布置的柱塞，通過靜壓平衡的滑靴緊貼著偏心行程定子。柱塞與滑靴球鉸相連，并通過卡簧鎖定。二個保持環將滑靴卡在行程定子上。泵轉動時，它依靠離心力和液壓力壓在定于內表面上。當轉子轉動時，由于定于的偏心作用，柱塞將作往復運動，它的行程為定于偏心距的2倍。定子的偏心距可由泵體上的徑向位置相對的兩個柱塞來調節。油液的進出通過泵體和配流軸上的流道，并由配流軸上吸油口控制，泵體內產生的液壓力被靜壓平衡的表面所吸收。摩擦副的靜壓平衡采取了過平衡壓力補償方法，形成了開環控制。支承驅動軸的軸承只起支承作用，不受其他外力的作用。液壓系統中:軸向柱塞泵是利用與傳動軸平行的柱塞在柱塞孔內往復運動所產生的容積變化來進行工作的。由于柱塞泵的柱塞和柱塞孔都是圓形零件，加工時可以達到很高的精度配合。
