摘要： A radial plunger pump has a motor housing (315); a motor (411) is provided therein and a pump housing a pump portion is provided therein. The pump portion works when the rotation of the mortor is transmitted to the pump portion through a shaft. The pump housing has a constant pressure chamber between the pump portion and the mortor. The constant pressure chamber is formed between a first seal member and a second seal member, both seal members are fixed to the pump housing. The constant pressure chamber is always open to the outer atmosphere through a constant pressure hole so that the vibration of the pressure within the constant pressure chamber can maintain the atomosphere pressure. The first and second seal member and the constant pressure chamber prevent the leakage of the oil from the pump housing toward the motor housing. Since a plate is provided within the costant pressure chamber in order to make the pressure at the opening portion of the constant pressure port increase, the foreign objects is well prevented to be introduced into the constant pressure chamber through the constant pressure hole.

摘要翻译：径向柱塞泵具有马达壳体（315）; 在其中设置有电动机（411），并且在其中设置有容纳泵部分的泵。当舵的旋转通过轴传递到泵部分时，泵部分工作。泵壳体在泵部分和榫体之间具有恒定的压力室。恒压室形成在第一密封构件和第二密封构件之间，两个密封构件都固定在泵壳体上。恒压室始终通过恒压孔向外部大气敞开，使得恒压室内的压力振动能保持大气压。第一和第二密封构件和恒定压力室防止油从泵壳体向马达壳体泄漏。由于为了使定压口的开口部分处的压力增加，在成本调节室内设置有板，因此可以防止异物通过恒压孔被引入恒压室。
