Abstract

Un conjunto servo reforzador para sistemas de freno de vehículos, en el que una pared móvil esta sujeta a presión diferencial controlada por medios de válvula, los cuales comprenden un cuerpo de válvula dotado de un orificio axial, dentro del que trabaja un miembro control de válvula con una porción de sección transversal no redonda, un aplaca soporte para permitir que la palca pase sobrela porción citada, siendo las formas de dichas porción y abertura tales que se impida que la placa pase sobre la porción en dirección inversa cuando la placa pase sobre la porción en dirección inversa cuando la placa haya sido girada un cierto ángulo adecuado respecto a la abertura, caracterizado porque el cuerpo de válvula va dotado de un rebajo (48) dispuesto substancialmente en posición transversal, dentro del cual se recibe una chaveta (49) dotada de conexión de juego libre con el miembro control de válvula (21) y que coopera con la placa soporte de diafragma (7) para evitar que gire respecto a la porción citada (41) a una posición en la que la placa pueda pasar sobre dicha porción, disponiendose de los medios adecuados (56) para mantener la chaveta en su posición.
