Abstract
La invención se refiere a un cilindro maestro con reacción hidráulica para un servomotor neumático de aumento de la potencia del freno que comprende un pistón principal (12) que recibe la energía del servomotor y un medio de reacción hidráulico que incluye un pistón de reacción (3) montado de forma deslizante en el pistón principal y que recibe una fuerza de accionamiento. La invención se caracteriza por el hecho de que el medio de reacción hidráulico comprende además un asiento de cierre (31), una pared en forma de anillo (4), un pistón de cambio de relación, de forma tubular (5) y un pistón flotante (6), el montaje está dispuesto de manera que el pistón de reacción (3) reciba una fuerza de reacción reducida cuando se aplica la fuerza de accionamiento de forma súbita.
