    • A master cylinder including a cylinder body having a cylindrical bore and an opening in the circumferential wall for a relief port communicating with the interior of hydraulic reservoir. A piston is slidably inserted into the cylindrical bore to form a hydraulic pressure generating chamber in the cylindrical bore. A cup seal is provided with an inner circumferential lip portion contacting with the piston, an outer circumferential lip portion slidably contacting with the inner circumferential wall of the cylindrical bore, and a base portion connecting the lip portions, which are so arranged as to face to the hydraulic pressure generating chamber. The cup seal cuts the communication between the hydraulic pressure generating chamber and the hydraulic reservoir through the relief port when the top end of the outer circumferential lip portion passes by the relief port. The improvement resides in means provided for rotating the cup seal relative to the cylindrical bore with movement of the piston at portions of the cup seal except those portions facing to the inner wall of the cylindrical bore.
    • 一种主缸,包括具有圆柱形孔的缸体和在周向壁中的用于与液压储存器内部连通的释放口的开口。 活塞可滑动地插入圆柱形孔中,以在圆柱孔中形成液压产生室。 杯形密封件设置有与活塞接触的内周唇部,与圆筒孔的内周壁可滑动接触的外周唇部,以及连接唇部的基部, 液压发生室。 当外周唇缘部分的顶端通过排放口时,杯形密封件通过排泄口切断液压产生室和液压容器之间的连通。 改进在于提供用于相对于圆柱形孔旋转杯形密封件的装置,其中活塞在杯形密封件的部分处移动,除了面向圆柱形孔的内壁的那些部分之外。

    • To provides a technique capable of replenishing a working fluid smoothly while employing a method for replacing an atmospheric air with the working fluid. The reservoir apparatus (10) includes a main reservoir (20) having an inlet opening for feeding a hydraulic fluid, and an auxiliary reservoir (50) connecting thereto through a piping (30). There is a diagonally extending connecting pipe (60) at the auxiliary reservoir (50). There is a recessed portion (80) at an opening portion (64) of an inner periphery of the connecting pipe (60). This recessed portion (80), when compared with the case where there is no such a recessed portion, serves to enlarge the opening portion (64) of the connecting pipe (60) and more smoothly flow the replenishment working fluid at a nearby area of the opening portion (64). By doing so, the opening portion (64) of the connecting pipe (60) can be more enlarged at the time of replenishment of the working fluid and formation of a film of the working fluid can be prevented at the opening portion (64).
    • 提供一种能够在使用用工作流体代替大气的方法的同时平稳地补充工作流体的技术。 储存装置(10)包括具有用于供给液压流体的入口的主储存器(20)和通过管道(30)与其连接的辅助储存器(50)。 在辅助容器(50)处具有对角延伸的连接管(60)。 在连接管(60)的内周的开口部(64)处具有凹部(80)。 与没有这样的凹部的情况相比,该凹部(80)用于扩大连接管(60)的开口部(64),并使补充工作流体在附近的区域 开口部分(64)。 通过这样做,可以在补充工作流体时使连接管(60)的开口部分(64)更大地扩大,并且可以防止在开口部分(64)形成工作流体膜。
