This paper deals with a new development of a swash-plate hydraulic pump. It is particularly designed to aim its usage in applications where environmental impacts should be concerned. Thus, the pump is based on not mineral-based oil but simple tap water. The Electro-Hydraulic Actuator (EHA), a linear motion generator operated by an electric motor installed to the proposed pump, can be attractive and expandable to small-to-medium pressure applications. Water is clean and safe, and the size of EHA is relatively small. New design features of the pump including the no-shoe retainer, the inclination angle adjustment screw, the rotating cylinder block, and the simple assembly structure enabled EHA. The pump was designed to have its static pressure of 1.4 MPa and the volumetric flow rate of 10 × 10³ mm³/s. To verify its performance, a series of experiments were constructed, and the maximum volumetric flow rate and pressure were found as 2935.87 mm³/s and 1.9 MPa, respectively. The maximum velocity of the actuator stroke was 9.35 mm/s. The EHA is controlled directly by the electric motor, and so a directional valve is not necessary. It is concluded the pump can be successfully used in small-to-medium pressure applications.

本文介绍了斜盘液压泵的新发展。它专门设计用于在应考虑环境影响的应用中使用。因此，该泵不是基于矿物油而是简单的自来水。电动液压执行器（EHA）是一种由安装在建议的泵上的电动机驱动的线性运动发生器，具有吸引力，并且可以扩展到中小型压力应用。水干净安全，EHA的尺寸相对较小。泵的新设计特征包括无滑套固定器，倾斜角度调节螺钉，旋转的气缸体以及简单的装配结构，从而实现了EHA。泵的设计静态压力为1.4 MPa，体积流量为10×10 ³ mm ³/ s。为了验证其性能，我们进行了一系列实验，得出最大体积流量和压力分别为2935.87 mm ³ / s和1.9 MPa。致动器行程的最大速度为9.35 mm / s。EHA由电动机直接控制，因此不需要方向阀。结论是，该泵可以成功用于中小型压力应用。
