    • A motor vehicle hydraulic brake system master cylinder, having at least one piston which is arranged in a housing and displaceable along an axis as a result of brake actuation and to which a pressure chamber which can be connected to wheel brakes, and a refill chamber is assigned, wherein the pressure chamber in the non-actuated state can be connected to a fluid reservoir via a compensating bore and on actuation of the brake can be isolated therefrom by means of a cup seal arranged on the piston in order to build up pressure. The master cylinder having a cup seal arranged in a radially open, encircling groove of the piston which groove is formed by a first and a second radially encircling projection, wherein when the brake actuation is released additional fluid is drawn from the refill chamber in the direction of the pressure chamber via the second projection.
    • 一种机动车辆液压制动系统主缸,具有至少一个活塞,该活塞布置在壳体中,并且由于制动器致动而沿轴线移动,并且可连接到车轮制动器的压力室和再填充室 其中,处于非致动状态的压力室可以经由补偿孔连接到流体储存器,并且通过布置在活塞上的杯形密封件可以将制动器的致动与其隔离,以便建立压力。 主缸具有布置在活塞的径向开放的环形凹槽中的杯形密封件,该凹槽由第一和第二径向环绕的突起形成,其中当释放制动器致动时,附加流体从再填充室沿方向 的压力室。

    • The invention relates to a piston unit having a captive spring for a cylinder, particularly for a tandem master cylinder of a motor vehicle, wherein the spring, with a first end, is supported at least indirectly on a piston and, with a second end, is supported on a retaining device that can be displaced relative to the piston, and the movement of the retaining device relative to the piston is limited by securing means.The invention is characterized in that the securing means have a projection, which is mounted in a non-detachable manner on the piston and whose free end is provided with a stop that limits the movement of the retaining device relative to the piston.
    • 本发明涉及一种活塞单元,其具有用于气缸的固定弹簧,特别是用于机动车辆的串联主缸,其中具有第一端的弹簧至少间接地支撑在活塞上,并且具有第二端, 被支撑在能够相对于活塞移位的保持装置上,并且保持装置相对于活塞的运动受到固定装置的限制。 本发明的特征在于,固定装置具有突出部,该突起以不可拆卸的方式安装在活塞上,并且其自由端设置有限制保持装置相对于活塞的运动的止挡件。
