Using parametric design way, water hydraulic axial piston pump's main internal parts include piston, slipper and valve plate were designed, which improves the design efficiency and quality.

运用参数化设计手段，对纯水液压轴向柱塞泵的主要部件包括柱塞、滑靴、配流盘等进行了设计。提高了设计效率和设计质量。

One reason for the slipper piston is that, on the short-stroke, over square engine, the piston skirt had to be cut away to make room for the counterweights on the crankshaft.

使用滑裙活塞的原因是：短行程发动机需除去部分活塞裙部，从而为曲轴的平衡重让出空间。

A lot of study showed that the friction of the ball friction coupling between piston and slipper obviously affected the life-span and the performance of the axial piston pump.

大量的研究表明，柱塞与滑靴之间的球铰副摩擦力很大程度上影响着轴向柱塞泵的性能及寿命。
