    摘要: The invention relates to a master cylinder (1) with reduced free travel (23). Current master cylinders have a free travel during the displacement of a piston (6) in a bore (5) of a master cylinder body (3). Such a free travel may be reduced with the aid of a frustoconical portion (24) in the piston, an orifice (14) for communication of hydraulic fluid being situated on said inclined wall, a gap (26) between the inclined wall and an inner wall (12) of the bore allowing a passage for hydraulic fluid capable of filling a pressure chamber (4). However, such inclined walls create a change in the slope of an outer wall (29) of the piston, this change being able to cause a separation of an inner lip (19) of a sealing cup (17). To prevent this separation, the invention provides that the inclined wall forms a convex rounded surface (32).

    摘要: The invention relates to a braking control system for automotive vehicles comprising a braking control member (1), a brake booster (4) and a brake master cylinder (5). The system of the invention further comprises a simulator (3) coupled pneumatically to the piston (42) of the brake booster (4). Said simulator (3) receives at least one braking command from the braking control member (1) and makes it possible to establish, in return, a difference in pressure between the front chamber (40) and the rear chamber (41) of the brake booster so as to control the displacement of the piston (42).Application: Brakes for automotive vehicles.
