Abstract: A cup for a master cylinder coming into contact with its primary piston or its secondary piston and subjected to the pressure of the brake fluid of the primary chamber and of the secondary chamber. The cup has two large grooves bordered: by a rib between the heel and the first groove, by a rib between the first groove and the second groove, by a rib between the second groove and the small grooves, these ribs being in protrusion relative to the cylindrical surface of the heel in the mounted position of the cup in order to separate the heel from the surface of the piston and form, between the heel and the surface of the piston, a gap with a film of brake fluid. Master cylinder notably a tandem master cylinder fitted with such cups.

Abstract: A primary piston composed of a skirt and an intermediate back wall having a rear face receiving the servobrake thrustrod and a forward face for the telescoping rod and the spring pushing the secondary piston. The front of the skirt has longitudinal grooves open in front and closed in the rear. The thickness of the skirt beneath the grooves and the part of the skirt between two successive grooves in the peripheral direction foam a front face enabling the principal piston to push the secondary piston. The principal piston is made of a single piece of plastic material.

Abstract: A primary piston is described of molded plastic and equipped with a functional metallic insert and at least one groove. The primary piston is installed in a master cylinder comprising at least the primary piston and a secondary piston, these being mounted in the bore hole of a master cylinder. These pistons can create pressure in a primary pressure chamber and a secondary pressure chamber, respectively, due to the action of a push rod on the primary piston.

Abstract: 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).

Abstract translation: 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，本发明提供了倾斜的壁形成凸的圆形表面（32）。
