SPECK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两个阶段。
进油过程
SPECK柱塞泵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

回油过程
SPECK柱塞泵柱塞向上供油，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 。
