Abstract

Un servofreno de vacío, el cual tiene un pistón de servo (19) herméticamente separado de la caja de servo (7) y un vástago de pistón (14), acoplado a un pedal de freno, para el accionamiento de una doble válvula (11/9 o bien 11, 12, o ambas a la vez) por medio de lo cual una cámara de trabajo (20) del servofreno puede ser conectada a una fuente de vacío o a una presión más alta; en la que la primera válvula (11, 12) está formada por un asiento de válvula (12) que hay en la caja de control (2) asociada al pistón de servo (19) y una válvula tubular (1) precargada hacia el asiento de válvula (11), y una segunda válvula (9, 11) está formada por la misma válvula tubular (1) y un pistón de válvula (16, 9) conectado al vástago del pistón (14); estando la caja de control (2) provista de una abertura (40) a través de la cual sobresale un miembro transversal (41) que limita el desplazamiento axial del pistón de válvula (16) respecto a la paja de control (2) y que sobresale radialmente de la abertura(40) y en la posición de reposo se apoya en un tope fijo, caracterizado porque el anillo deslizante de guía (24) que sujeta a la caja de control (2) y que está sujetado en la caja de servo (7) tiene en su costado del lado del pistón de servo (19) una banda (8) de una goma elástica contra la que se apoya el miembro transversal (41) en la posición de reposo.
