摘要： A hydraulic seal system includes a seal ring groove and a seal ring mounted in the seal ring groove. The seal ring and seal ring groove are rotatable relative to each other, and have sealing sides, respectively, which are put into pressure contact with each other by a sealing hydraulic pressure. The seal ring is made of a synthetic resin to have a fixed elasticity. The sealing side of the seal ring is formed into a convex curved surface with its radially central portion raised, so that when a hydraulic pressure is applied, the sealing side can be compressedly deformed to define a hydraulic pocket. Thus, the formation and retaining of an oil film at the pressure contact portions of the sealing sides is promoted.

摘要： In a sealing device, a crank-shaped oil channel is defined in an abutment of a sealing ring for sealing between a shaft member and a housing which surrounds the shaft member and is rotatable relative the shaft member. The crank-shaped oil channel is comprised of a first oil channel portion and a second oil channel portion which extend axially, and a third oil channel portion which connects the first and second oil channel portions to each other. If the sealing ring is thermally expanded circumferentially due to a change in temperature, the sectional area of the flow path in each of the first and second oil channel portions is varied, but the sectional area of the flow path in the third oil channel portion is not substantially varied. Therefore, it is possible to leak a given amount of an oil from one side of the sealing ring through the crank-shaped oil channel to the other side, thereby preventing the wearing of the shaft member caused by foreign matter, such as an iron powder, contained in the oil.
摘要翻译：在密封装置中，曲轴形的油通道被限定在用于在轴构件和围绕轴构件的壳体之间进行密封并且可相对于轴构件旋转的密封环的邻接处。曲柄形油路由第一油路部和轴向延伸的第二油路部以及将第一和第二油路部彼此连接的第三油路部构成。如果密封环由于温度变化而周向热膨胀，则第一和第二油道部分中的每一个中的流路的截面面积是变化的，但是第三油路部分中的流路的截面面积是没有实质的变化。因此，可以将密封环的一侧的给定量的油从曲轴形油路泄漏到另一侧，从而防止由铁粉等异物引起的轴构件的磨损，含在油中。

摘要： One end of a seal ring retained in a seal ring groove is formed in such a manner that it is offset radially inwardly from the other end, so that oil is permitted to leak by opening an abutment joint formed by the two ends in a condition in which no hydraulic pressure is applied. If a hydraulic pressure is supplied to bring a hydraulic actuator into an engaged state, the one end of the seal ring is deformed radially outwardly by the hydraulic pressure to come into close contact with a sealing surface and to close the abutment joint, thereby preventing the oil from-leaking past the oil ring. Consequently, upon engagement of the hydraulic actuator, a sealing property or salability of the oil can be assured, and upon releasing of the engagement of the hydraulic actuator, an oil leaking property of the seal ring can be provided, leaking property of the oil can be provided, thereby enhancing the responsiveness of the hydraulic actuator.
摘要翻译：保持在密封环槽中的密封环的一端形成为从另一端向径向向内偏移的方式形成，从而通过在两端的状态下打开由两端形成的抵接接头而允许油泄漏没有施加液压。如果供给液压以使液压致动器进入接合状态，则密封环的一端由于液压而径向向外变形，以与密封面紧密接触并且闭合邻接接头，从而防止油通过油环泄漏。因此，在液压致动器接合时，能够确保油的密封性或油性，在解除液压致动器的卡合时，能够提供密封环的漏油特性，油罐的泄漏性能从而提高液压致动器的响应性。

摘要： In a hydraulic brake for a transmission, an assist piston, a reaction piston and a main piston are accommodated on a cylinder. The assist piston has a first acting portion in abutment against the main piston, and the main piston has a second acting portion facing one end of stacked frictional engaging elements. The assist piston and the main piston are moved rightwardly by a hydraulic pressure supplied to a first oil chamber and a second oil chamber to bring the frictional engaging elements into engagement with one another. The first and second acting portions are superposed as viewed axially, thereby preventing a jarring of the assist piston and the main piston. In one embodiment, each of the pistons is formed from a pressed article, whereby the machining cost can be reduced and, moreover, oil passages connecting the first and second oil chambers can be provided in a simple manner.
