    • The invention relates to a master cylinder (1) with reduced free travel (23). Current master cylinders have a free travel during the displacement of a piston (6) in a bore (5) of a master cylinder body (3). Such a free travel may be reduced with the aid of a frustoconical portion (24) in the piston, an orifice (14) for communication of hydraulic fluid being situated on said inclined wall, a gap (26) between the inclined wall and an inner wall (12) of the bore allowing a passage for hydraulic fluid capable of filling a pressure chamber (4). However, such inclined walls create a change in the slope of an outer wall (29) of the piston, this change being able to cause a separation of an inner lip (19) of a sealing cup (17). To prevent this separation, the invention provides that the inclined wall forms a convex rounded surface (32).
    • 本发明涉及具有减小的自由行程(23)的主缸(1)。 在主缸体(3)的孔(5)中的活塞(6)的移动期间,当前主缸具有自由行程。 借助于活塞中的截头圆锥形部分(24)可以减少这种自由行程,用于连接位于所述倾斜壁上的液压流体的孔口(14),位于倾斜壁和内壁之间的间隙(26) 所述孔的壁(12)允许能够填充压力室(4)的液压流体的通道。 然而,这种倾斜壁产生活塞的外壁(29)的斜率的变化,这种变化能够导致密封杯(17)的内唇缘(19)的分离。 为了防止这种分离,本发明提供了倾斜壁形成凸的圆形表面(32)。
