美国威格士PVH系列变量柱塞泵*
VICKERS变量柱塞泵，可以串联齿轮泵。由齿轮泵与柱塞泵共同构成的油源系统，可以控制整体的功率曲线，使得恒功率控制不再局限于对单个油泵的控制，而是整个系统。
VICKERS变量柱塞泵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。
进口VICKERS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。
