美国威格士柱塞泵PVH131Q1C-RSF-13S-10-C25-31
威格士VICKERS柱塞泵进油过程：
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。
威格士VICKERS柱塞泵回油过程：
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。
威格士VICKERS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 。
威格士VICKERS柱塞泵缸体镶装铜套的，可以采用更换铜套的方法安装。首先把一组柱塞杆外径修整到统一尺寸，再用1000#以上的砂纸抛光外径。
缸体安装铜套的三种方法：
（a）缸体加温热装或铜套低温冷冻挤压，过盈装配；
（b）采有乐泰胶粘着装配，这咱方法要求铜外套外径表面有沟槽；
（c）缸孔攻丝，铜套外径加工螺纹，涂乐泰胶后，旋入装配。
（2）熔烧结合方式的缸体与铜套，修复方法如下：
（a）采用研磨棒，手工或机械方法研磨修复缸孔；
（b）采用座标镗床，重新镗缸体孔；
（c）采用铰刀修复缸体孔。
