本专利阐述了大转矩径向柱塞液压马达的平面配流盘性能。该机构与一般轴配流机构不同,利用压力压紧装置使配流盘平面压向转子平面,以保持密封。同时还有一环形平衡腔,以平衡压紧装置的压力,使配流盘与转子的贴合面相互保持一定间隙,以便能相互转动。本专利介绍了一些设计要求和附加的压力保持阀结构。 This patent describes the performance of the face plate with a large torque radial piston hydraulic motor. The mechanism and the general axis of the different flow institutions, the use of pressure clamping device so that the face plate pressure plate to the rotor plane to maintain the seal. At the same time, there is an annular balance chamber to balance the pressure of the pressing device so that the fitting surfaces of the valve plate and the rotor can maintain a certain gap with each other so as to be able to rotate with each other. This patent describes some design requirements and additional pressure-retaining valve configurations.
