Abstract

Una válvula de freno, la cual tiene los husillos de control de los que cada uno de ellos establece la conexión de un circuito de freno con una fuente de fluído o con un depósito no presurizado, en el que el primer husillo de control es mecánicamente desplazable por medio de un pedal de freno y el segundo husillo de control es desplazable hidraúlicamente al tener asignada una cámara de presión que está en comunicación permanente en el circuito de freno asociado al primer husillo de control y en el interior del cual penetra con una superficie frontal efectiva al segundo husillo de control, caracterizada porque el segundo husillo de control (32) tiene dos superficies activas adicionales opuestas (36, 38), de las que la primera superficie activa(36) es accionable `por la presión de la cámara de presión (31) asociada al segundo husillo de control (32) y la segunda superficie efectiva (38) da frente a una cámara de contrapresión (37) en comunicación permanente con el circuito de freno (8) asociado al segundo husillo de control (32).
