本文介绍了一项对油液压轴向活塞泵中气缸压力和流动的研究。基于圆柱体中流体依从性的影响以及改进的模型之间的理论模型进行了比较，该模型解释了油动量在端口板区域中的影响。通过与实验测试结果进行比较，可以验证改进的模型，并用于分析端口板和浮雕凹槽设计对气缸压力和泵流动纹波的影响。发现陡峭的倾斜三角形横截面是最令人满意的设计。
This paper describes a study of the cylinder pressure and flow in an oil hydraulic axial piston pump. A comparison is made between a theoretical model based on the effects of fluid compliance within the cylinder, and an improved model which accounts for the influence of oil momentum in the port plate region. The improved model is validated by comparison with experimental test results and is used to analyze the influence of port plate and relief groove design on cylinder pressure and pump flow ripple. A steeply sloping triangular cross-section groove was found to be the most satisfactory design.
