Abstract
Una instalación neumática para el frenado de vehículos, en especial para el frenado electroneumático de vehículos de carril, con una tubería de alimentación, una válvula conmutable de varias vías, un regulador de presión dependiente de la carga y, al menos, una cámara de presión, estando la válvula de varias vías conectada a tubería de alimentación y unida con el regulador de presión y la cámara de presión y uniendo, en una posición de mando la tubería de alimentación con la cámara de presión, caracterizada porque está dispuesta una doble válvula de retención entre la válvula de varias vías, el regulador de presión y la cámara de presión, de cuyas dos entradas la primera está unida con la válvula de varias vías y la segunda con el regulador de presión, y cuya salida está unida con la cámara de presión, porque en la otra posición de mando de la válvula de varias vías la doble válvula de retención está unida con una salida para rebajar la presión en la cámara de presión, y porque, para la limitación, dependiente de la carga, de la fuerza de frenado, conmuta la doble válvula de retención cuando la presión en la primera entrada es rebasada por abajo respecto a la presión dependiente de la carga en la segunda entrada.
