    • The hydraulic brake system with slip control comprises a master cylinder piston for operating a wheel brake, in which hydraulic medium tapped from the wheel brake during slip control will be supplied to the wheel brake from an auxiliary pressure source via a master cylinder gasket acting as check valve. The operating stroke of the master cylinder piston is limited by pressurization of a positioning piston through which a master cylinder piston rod is passed in a sealed manner and which is guided axially displaceable in a sealed manner in a housing. In order to prevent an abrupt movement of the positioning piston upon pressurization the positioning piston is constructed as a stepped piston whose smaller diameter is sealed with respect to the housing and having a piston step which in combination with the seal between the smaller diameter portion of the positioning piston and the housing annular chamber with a volume which is dependent on the pedal travel. The annular chamber has a throttling connection to the front surface of the positioning piston pressurized in case of slip control, which throttling connection has a check valve which opens towards the annular chamber.
    • 具有滑动控制的液压制动系统包括用于操作车轮制动器的主缸活塞,其中在滑动控制期间从车轮制动器敲击的液压介质将通过作为检查的主缸垫片从辅助压力源供给到车轮制动器 阀。 主缸活塞的操作行程通过定位活塞的加压来限制,通过该定位活塞,主缸活塞杆以密封方式通过,并且以密封方式被引导轴向移动到壳体中。 为了防止定位活塞在加压时的突然移动,定位活塞被构造为阶梯式活塞,其较小的直径相对于壳体被密封并且具有活塞步骤,该活塞步骤与密封件的较小直径部分 定位活塞和壳体环形室,其体积取决于踏板行程。 在滑动控制的情况下,环形室具有到定位活塞的前表面的节流连接,该节流连接具有朝向环形室打开的止回阀。
