摘要： A radial piston pump for the automative brake system has a rotor (130), a couple of pistons (131, 132) reciprocated within a respective cylinder formed within the rotor (130) and a bearing (140). The top end of the piston (131, 132) abuts directly to the inner surface so that no show is existed therebetween. The relationship within a starting point (1141) and a finishing point (1142) of a suction groove (114), a starting point (1131) and a finishing point (1132) of a discharge groove (113) and an opening port (1311, 1312) the cylinder is designed in such a manner that at least one of a couple of cylinders connects to the suction groove during a whole rotation of the rotor (130).

摘要： A radial piston pump has a rotor (2) provided within a cylinder chamber (30) in such a manner that a center axis of the rotor (2) is offset from a center axis of the cylinder chamber (30). The rotor (2) has three working chambers (8) a piston (6) is slidably provided each of which. Each working chamber (8) may connect with a suction groove (9) or a discharge groove (10) so that there exists a couple of situations, one of which is that two working chambers (8) connect with the discharge chamber simultaneously and another one of which is that single working chamber connects with the discharge chamber. In order to make the forcing point at which total biassing force of the piston (6) is focussed move gradually, the radial piston pump has a delay angle at a front side of the suction chamber. Namely a pressure within the working chamber (8) is preliminary reduced before the working chamber (8) connects to the suction groove (9) so that the forcing point should shift gradually.
摘要翻译：径向活塞泵具有设置在气缸室（30）内的转子（2），使得转子（2）的中心轴线偏离气缸室（30）的中心轴线。转子（2）具有三个工作室（8），活塞（6）以可滑动的方式设置在每个工作室中。每个工作室（8）可以与吸入槽（9）或排出槽（10）连接，从而存在一些情况，其中之一是两个工作室（8）同时与放电室连接，另一个其中之一是单个工作室与放电室连接。为了使活塞（6）的总偏置力被聚焦的施力点逐渐移动，径向柱塞泵在吸入室的前侧处具有延迟角。即，在工作室（8）连接到吸入槽（9）之前，工作室（8）内的压力初步降低，使得施力点应逐渐移位。

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。
