叶片泵分为双作用泵和单作用泵：
双作用泵工作原理：它由定子、转子、叶片和配油盘等组成。定子内壁近似椭圆形。叶片安装在转子径向槽内并可沿槽滑动，转子与定子同心安装。当转子转动时，叶片在离心力的作用下压向定子内表面，并随定子内表面曲线的变化而被迫在转子槽内往复滑动，相邻两叶片间的密封工作腔就发生增大和缩小的变化。叶片由小半径圆弧向大半径圆弧处滑移时，密封工作腔随之逐渐增大形成局部真空，于是油箱中油液通过配油盘上吸油腔吸入；反之将油压出。转子每转一周，叶片在槽内往复滑移2次，完成2次吸油和2次压油，并且油压所产生的径向力是平衡的，故称双作用式，也称平衡式。
单作用式叶片泵工作原理：主要由定子、转子、叶片和配油盘等组成。定子的内表面是一个圆柱形，转子偏心安装在定子中，即有一个偏心距e，叶片装在转子径向滑槽中，并可在槽内径向滑动。转子转动时，在离心力和叶片根部压力油的作用下，叶片紧贴在定子内表面上，这样相邻两片叶片间就形成了密封工作腔。在其中一边，叶片逐渐伸出，密封工作腔逐渐增大，形成局部真空，形成吸油；反之，另一边，形成压油。转子每转一周，叶片在滑槽内往复滑移1次，完成1次吸油1次压油。油压所产生的径向力是不平衡的，故称单作用式，也称不平衡式叶片泵。
