威格士变量柱塞泵
威格士变量柱塞泵是往复泵的一种，属于体积泵，其柱塞靠泵轴的偏心转动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，工作室内压力降低，出口阀关闭，低于进口压力时，进口阀打开，液体进入；柱塞内推时，工作室压力升高，进口阀关闭，高于出口压力时，出口阀打开，液体排出。带滑靴结构的轴向柱塞泵是目前使用zui广泛的轴向柱塞泵，安放在缸体中的柱塞通过滑靴与斜盘相接触，当传动轴带动缸体旋转时，斜盘将柱塞从缸体中拉出或推回，完成吸排油过程。柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。变量机构用来改变斜盘的倾角，通过调节斜盘的倾角可改变泵的排量。
概述
威格士变量柱塞泵柱塞往复运动总行程L是不变的，由凸轮的升程决定。柱塞每循环的供油量大小取决于供油行程,供油行程不受凸轮轴控制是可变的。供油开始时刻不随供油行程的变化而变化。转动柱塞可改变供油终了时刻，从而改变供油量。柱塞泵工作时，在喷油泵凸轮轴上的凸轮与柱塞弹簧的作用下，迫使柱塞作上、下往复运动，从而完成泵油任务，泵油过程可分为以下三个阶段。
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。
供油过程
当凸轮轴转到凸轮的凸起部分顶起滚轮体时，柱塞弹簧被压缩，柱塞向上运动，燃油受压，一部分燃油经油孔流回喷油泵上体油腔。当柱塞顶面遮住套筒上进油孔的上缘时，由于柱塞和套筒的配合间隙很小（0.0015-0.0025mm）使柱塞顶部的泵油室成为一个密封油腔，柱塞继续上升，泵油室内的油压迅速升高，泵油压力>出油阀弹簧力+高压油管剩余压力时，推开出油阀，高压柴油经出油阀进入高压油管，通过喷油器喷入燃烧室。
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。
变量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 。
