力士樂單作用葉片泵的工作原理：泵由轉(zhuǎn)子、定子、葉片、配油盤和端蓋等部件所組成。定子的內(nèi)表面是圓柱形孔。轉(zhuǎn)子和定子之間存在著偏心。葉片在轉(zhuǎn)子的槽內(nèi)可靈活滑動，在轉(zhuǎn)子轉(zhuǎn)動時的離心力以及通入葉片根部壓力油的作用下，葉片頂部貼緊在定子內(nèi)表面上，于是兩相鄰葉片、配油盤、定子和轉(zhuǎn)子間便形成了一個個密封的工作腔。當(dāng)轉(zhuǎn)子按逆時針方向旋轉(zhuǎn)時，圖右側(cè)的葉片向外伸出，密封工作腔容積逐漸增大，產(chǎn)生真空，于是通過吸油口6和配油盤5上窗口將油吸入。而在圖的左側(cè)。葉片往里縮進，密封腔的容積逐漸縮小，密封腔中的油液經(jīng)配油盤另一窗口和壓油口被壓出而輸出到系統(tǒng)中去。這種泵在轉(zhuǎn)子轉(zhuǎn)一轉(zhuǎn)過程中，吸油壓油各一次，故稱單作用泵。轉(zhuǎn)子受到徑向液壓不平衡作用力，故又稱非平衡式泵，其軸承負(fù)載較大。改變定子和轉(zhuǎn)子間的偏心量，便可改變泵的排量，故這種泵都是變量泵。
