REXROTH柱塞泵，是由電動機提供泵的動力，經鼓型齒聯軸器帶動減速機轉動。由減速機減速帶動曲軸旋轉。通過曲柄連桿機構，將旋轉運動轉變?yōu)槭诸^和柱塞為往復運動。當柱塞向后死點移動時，泵容積腔逐步增大，泵腔內壓力降低，當泵腔壓力低于進口壓力時，吸入閥在進口端壓力作用下開啟，液體被吸入；當柱塞向前死點移動時，泵腔內壓力增大，此時吸入閥關閉，排出閥打開，液體被擠出液缸，達到了吸入和排出的目的。

      工作時，在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下，迫使柱塞作上、下往復運動，從而完成泵油任務，泵油過程可分為以下三個階段。

      結論：通過上述討論，得出下列結論

      ① 柱塞往復運動總行程L是不變的，由凸輪的升程決定。

      ② 柱塞每循環(huán)的供油量大小取決于供油行程，供油行程不受凸輪軸控制是可變的。

      ③ 供油開始時刻不隨供油行程的變化而變化。

      ④ 轉動柱塞可改變供油終了時刻，從而改變供油量。
