    • A piston (21) for a tandem master cylinder (41) is provided. The piston (21) comprises a cylindrical body (23) within which a hollow chamber (25) is formed. The hollow chamber (25) is blocked off by a partitioning portion (27) adjacent to one end of the cylindrical body (23) and open at the other end (28). At least one slot (33) is formed in an outer wall of the cylindrical body (23) at the open end (28) of the hollow chamber (25). A tandem master cylinder (41) comprising the piston (21) is also provided. The piston (21) may be manufactured by molding process without requiring complicated molds. Furthermore, the process for molding the piston (21) is relatively simple. The tandem master cylinder (41) has a simple structure and the reduced number of parts, thereby being capable of being manufactured in a low-cost manner.
    • 提供了一种用于串联主缸(41)的活塞(21)。 活塞(21)包括圆筒体(23),在其中形成中空室(25)。 中空室25被与圆筒体23的一端相邻的分隔部27而被封闭,另一端28断开。 在中空室(25)的开口端(28)处,至少一个槽(33)形成在筒体(23)的外壁上。 还提供了包括活塞(21)的串联主缸(41)。 活塞(21)可以通过模制工艺制造而不需要复杂的模具。 此外,用于模制活塞(21)的过程相对简单。 串联主缸(41)具有简单的结构和减少的部件数量,从而能够以低成本的方式制造。
