Abstract

Un servofreno para vehículos automóviles, con una caja de baja presión dividida con estanqueidad, por un tabique que puede moverse axialmente en una cámara de baja presión y una cámara de trabajo, teniendo un tubo, de refuerzo, que se extiende axialmente por la caja de baja presión, cuyos extremos están fijados a ambas paredes exteriores de la caja de baja presión y un diafragma enrollable unido con estanqueidad de tabique móvil, habiéndose una válvula de control mecánicamente accionable para conectar la cámara de trabajo a la cámara de baja presión o a la atmósfera, siendo el accionamiento de esta válvula de control axialmente desplazable en el tubo de refuerzo y estando dicho alojamiento de válvula conectado por una barra de empuje a un pistón de accionamiento de un cilindro principal que está fijado a la caja de baja presión del lado del vacío parcial e igualmente conectado a través de un manguito que rodea a dicha barra de empuje a unos nervios radiales del tabique móvil, atravesando dichos nervios el tubo de refuerzo por unas ranuras longitudinales que hay en el mismo, caracterizado porque los nervios radiales (23) del tabique móvil (2) están diseñados en forma de lengüetas planas situadas en, un mismo plano las cuales están enganchadas por detrás, del lado de la cámara de vacío parcial, por un borde prominente circular (22) vuelto en ángulo radialmente hacia afuera, del manguito (21) que está unido al alojamiento de válvula (17), y porque la distancia e entre el diafragma enrollable (13) y el extremo de las ranuras longitudinales (29) del tubo de refuerzo (5) del lado de la cámara de trabajo es igual, por lo menos, a la mitad de la carrera de trabajo del tabique axialmente móvil (2).
