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。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。

柱塞泵结构形式

柱塞泵分为轴向柱塞泵和径向柱塞泵两种代表性的结构形式;由于径向柱塞泵属于一种新型的技术含量比较高的高效泵，随着不断加快，径向柱塞泵必然会成为柱塞泵应用领域的重要组成部分.
