原装YUKEN日本油研双联叶片泵PV2R12-8-47-F-REAA-40叶片泵转子旋转时，叶片在离心力和压力油的作用下，尖部紧贴在定子内表面上。这样两个叶片与转子和定子内表面所构成的工作容积，先由小到大吸油后再由大到小排油，叶片旋转一周时，完成两次吸油与排油。
泵由转子1、定子2、叶片3、配油盘和端盖等部件所组成。定子的内表面是圆柱形孔。转子和定子之间存在着偏心。叶片在转子的槽内可灵活滑动，在转子转动时的离心力以及通入叶片根部压力油的作用下，叶片顶部贴紧在定子内表面上，于是两相邻叶片、配油盘、定子和转子间便形成了一个个密封的工作腔。当转子按逆时针方向旋转时，图右侧的叶片向外伸出，密封工作腔容积逐渐增大，产生真空，于是通过吸油口6和配油盘5上窗口将油吸入。而在图的左侧。叶片往里缩进，密封腔的容积逐渐缩小，密封腔中的油液经配油盘另一窗口和压油口1被压出而输出到系统中去。这种泵在转子转一转过程中，吸油压油各一次，故称单作用泵。转子受到径向液压不平衡作用力，故又称非平衡式泵，其轴承负载较大。改变定子和转子间的偏心量，便可改变泵的排量，故这种泵都是变量泵。
Yuken油研叶片泵PV2R12双联泵系列本型泵由同一轴驱动的两个PV2R型单泵并联组装在同一壳体内而成。
输出流量可以输向两个独立的回路。型号说明
