PVH063R01AA10H002000AW1001AB010A柱塞油泵进油过程
      当凸轮的凸起部分转过去后，在弹簧力的作用下，柱塞向下运动，柱塞上部空间（称为泵油室）产生真空度，当柱塞上端面把柱塞套上的进油孔打开后，充满在油泵上体油道内的柴油经油孔进入泵油室，柱塞运动到下止点，进油结束
PVH063R01AA10H002000AW1001AB010A柱塞油泵回油过程
      柱塞向上供油，当上行到柱塞上的斜槽（停供边）与套筒上的回油孔相通时，泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通，油压骤然下降，出油阀在弹簧力的作用下迅速关闭，停止供油。此后柱塞还要上行，当凸轮的凸起部分转过去后，在弹簧的作用下，柱塞又下行。此时便开始了下一个循环。柱塞泵以一个柱塞为原理介绍，一个柱塞泵上有两个单向阀，并且方向相反，柱塞向一个方向运动时缸内出现负压，这时一个单向阀打开液体被吸入缸内，柱塞向另一个方向运动时，将液体压缩后另一个单向阀被打开，被吸入缸内的液体被排出。这种工作方式连续运动后就形成了连续供油 。
