美国VICKERS威格士柱塞泵是依靠柱塞与缸体内孔面来形成密封工作容积的。由于柱塞与缸体内孔均为圆柱表面，因此加工方便，配合精度高，密封性能好。故柱塞泵常做成高压泵。
优点：压力高、结构紧凑、效率高及流量调节方便。
缺点：结构复杂，价格较贵。
柱塞泵按柱塞排列方向的不同，分为轴向柱塞泵和径向柱塞泵。在此，简要介绍轴向柱塞泵和回转式径向柱塞泵。
轴向柱塞泵。轴向柱塞泵由配流盘、缸体（转子）、柱塞和斜盘等主要零件组成。在配流盘上开有两个弧形沟槽，分别与泵的吸、压油口连通，形成吸油腔和压油腔。斜盘、配流盘均与泵体相固定，柱塞在弹簧的作用下以球形端头与斜盘接触。两个弧形沟槽彼此隔开，保持一定的密封性。斜盘相对于缸体的夹角为γ。原动机通过传动轴带动缸体旋转，柱塞就在柱塞孔内作轴向往复滑动。处于π～2π范围内的柱塞向外伸出，使其底部的密封容积增大，将油吸入；处于0～π范围内的柱塞向缸体内压入，使其底部的密封容积减小，把油压往系统中。
显然，泵的输油量决定于柱塞往复运动的行程长度，也就是决定于斜盘的倾角γ。如果γ角可以调整，就成为变量泵。γ角越大，输油量也就越大。
径向柱塞泵。所示当转子旋转时，柱塞在离心力作用下，它的头部与定子内表面紧紧接触，由于转子与定子之间有一个偏心量е，所以柱塞在随转子转动的同时，又在柱塞孔内作径向往复滑动。当转子按图中箭头所示方向旋转时，上半周的柱塞皆往外滑动，柱塞孔内的密封容积增大，于是通过轴向孔吸油；下半周的柱塞皆往里滑动，柱塞孔内的密封容积减少，于是通过轴向孔压油。
