A master cylinder for a braking system is described. The master cylinder includes a chamber (120) delimited by a piston (110) and supplied from a brake fluid reservoir installed on the top of the master cylinder by an end fitting engaged in a nozzle on the body of the master cylinder. The piston (110) has a nose (111) of reduced section upstream of its skirt (112) guided in the bore hole (102) of the master cylinder (100) and the nozzle (104) is connected to the chamber (120) by a drill hole (105) issuing into the chamber (120) at least partly upstream of the piston (110) in rest position. A valve module (200) is installed in the drill hole (105) to manage communication between the reservoir and the chamber (120) as a function of the position of the piston (110) and the pressure in the chamber (120) with respect to the pressure in the reservoir.
用于制动系统的主缸。主缸包括由活塞(110)界定的腔室(120),腔室(120)由安装在所述主缸顶部上的制动液储存器通过接合在主缸本体喷口中的接头进行馈送。活塞(110)在活塞(110)的裙部(112)上游具有横截面减小的鼻部(111),其在所述主缸(100)的镗孔(102)中被引导,且喷口(104)通过孔(105)连接到所述腔室(120),所述孔(105)在处于休息位置的活塞(110)上游至少部分地通向所述腔室(120)。阀模块(200)安装在所述孔(105)中,用于根据所述活塞(110)的位置和相对于储存器中压力的腔室(120)内的压力管理所述储存器与所述腔室(120)之间的连通。
