Abstract

Un conjunto de servofreno de vacío y cilindro maestro de freno (23), teniendo dicho servofreno un tabique móvil (46) que está sujeto con cierre hermético a la caja de servo (1) y una caja de control (7) que actúa conjuntamente con dicho tabique móvil (46) y que contiene una doble válvula (8, 13, 19) y con un pistón de válvula (9) deslizable por la acción de un vástago de pistón (11), actuando el extremo de dicho pistón de válvula (9) del lado del cilindro maestro a través de un dispositivo de reacción (10) sobre una barra de empuje (12), la cual, por su parte acciona al pistón escalonado (25) de la barra de empuje del cilindro maestro (23) estando este cilindro maestro embridado a una de las semicajas (16) de la caja de servo, caracterizado porque dicha barra de empuje (12) está sujeta a dicha caja de control (7) a través de una caperuza (21) sujetada a dicha caja de control (7), proveyéndose entre dicha caperuza (21) y dicha barra de empuje (12) un juego axial (x) mediante el cual dicha barra de empuje (12) puede ser desplazada en relación con dicha caja de control (7) en la dirección longitudinal de la caja, y actuando dicha caperuza (21) conjuntamente con un manguito (27) que, al producirse el desplazamiento de dicha barra de empuje (12) respecto a dicha caja de control (7), acciona a una primera válvula (26, 27) que enlaza a una cámara anular (28) situada detrás del escalón ancho (a, 29) de dicho pistón (25) de dicha barra de empuje con la cámara de presión (40) del circuito primario a través de un conducto (36, 36'') que hay en dicho pistón (25) de dicha barra de empuje, y a través de una segunda válvula (32) cierra una tobera de entrada (31) situada entre la boquilla de enlace (30) con un depósito del fluido y dicha cámara anular (28).
