Master brake cylinder with integrated transport lock
摘要：
A master cylinder (10) for a vehicle hydraulic brake system has a housing (12) with a bore (14) formed therein, which is open at one end and in which a first pressure piston (16) and a second pressure piston (18) are guided sealingly and displaceably along an axis (A). Acting counter to an actuating direction (X) upon the first pressure piston (16) is a restrained first restoring spring (34) and upon the second pressure piston (18) a second restoring spring (52). In order, in a transportation or disassembly state of the master cylinder (10), to prevent the first pressure piston (16) from being pressed excessively out of the bore (14), the second pressure piston (18) is supported by means of a stop component (66) counter to the actuating direction (X) positively in the housing (12) of the master cylinder (10).
摘要（中）：

用于车辆液压制动系统的主缸（10）具有壳体（12），其中形成有在其中的孔（14），其在一端是敞开的，第一压力活塞（16）和第二压力活塞（18 ）沿着轴线（A）被密封地和可移位地引导。 与第一压力活塞（16）上的致动方向（X）相反的作用是约束的第一复原弹簧（34），并且在第二压力活塞（18）上是第二复原弹簧（52）。 为了在主缸（10）的运输或拆卸状态下，为了防止第一压力活塞（16）被过度压出孔（14），第二压力活塞（18）通过 与主缸（10）的壳体（12）中的致动方向（X）相对的止动部件（66）。
