Abstract

Un servofreno de vacío compuesto de una caja vacío (1, 2) que está dividida al menos por un tabique divisorio (4, 7) en por lo menos una cámara de vacío (6) y una cámara de trabajo (5), y de un tabique divisorio (4, 7) que está conectado a un cuerpo central de control (3) axialmente desplazable que contiene un conjunto de válvula (20, 22, 25) actuando dicho cuerpo central de control (3) sobre un miembro transmisor de la fuerza (16) por intermedio de un dispositivo de reacción (17), caracterizado porque el pistón de válvula (22) que actúa en cooperación con la válvula tubular (25) de conjunto de válvula (20, 22, 25) está diseñado en su extremo, del lacio de la placa de válvula (54) de la válvula tubular (25) en forma de un tronco de cono recto cuya superficie lateral está frente a la válvula tubular (25), estando dicha superficie lateral (52) del tronco de cono, con la válvula en su posición de cerrada, haciendo tope con hermetismo con el borde anular (50) que la superficie frontal (54) de la válvula tubular (25) forma con su propia cara interior, o bien con dicha superficie frontal (54) o con uno y otra a la vez.
