| 摘要 |
The invention relates to a master cylinder with hydraulic reaction, comprising a working chamber (12) in which there slides, under the action of a pushrod (50), a hollow main piston (13) inside which a reaction piston (14), itself moved by a plunger (80), delimits a reaction chamber (15) which communicates with the working chamber (12), a prestressed spring (16) offering resistance to a movement of the reaction piston (14) in the opposite direction (X+X-) from its actuating direction (X-X+).According to the invention, a sliding ring (18) is arranged opposite the plunger (80) so that actuation of the reaction piston (14) by the plunger (80) is also accompanied by compression of the spring (16).
