葉片泵分為雙作用泵和單作用泵：

    雙作用泵工作原理：它由定子、轉子、葉片和配油盤等組成。定子內壁近似橢圓形。葉片安裝在轉子徑向槽內并可沿槽滑動，轉子與定子同心安裝。當轉子轉動時，葉片在離心力的作用下壓向定子內表面，并隨定子內表面曲線的變化而被迫在轉子槽內往復滑動，相鄰兩葉片間的密封工作腔就發生增大和縮小的變化。葉片由小半徑圓弧向大半徑圓弧處滑移時，密封工作腔隨之逐漸增大形成局部真空，于是油箱中油液通過配油盤上吸油腔吸入；反之將油壓出。轉子每轉一周，葉片在槽內往復滑移2次，完成2次吸油和2次壓油，并且油壓所產生的徑向力是平衡的，故稱雙作用式，也稱平衡式。

  單作用式葉片泵工作原理：主要由定子、轉子、葉片和配油盤等組成。定子的內表面是一個圓柱形，轉子偏心安裝在定子中，即有一個偏心距e，葉片裝在轉子徑向滑槽中，并可在槽內徑向滑動。轉子轉動時，在離心力和葉片根部壓力油的作用下，葉片緊貼在定子內表面上，這樣相鄰兩片葉片間就形成了密封工作腔。在其中一邊，葉片逐漸伸出，密封工作腔逐漸增大，形成局部真空，形成吸油；反之，另一邊，形成壓油。轉子每轉一周，葉片在滑槽內往復滑移1次，完成1次吸油1次壓油。油壓所產生的徑向力是不平衡的，故稱單作用式，也稱不平衡式葉片泵。
