Abstract

Instalación de frenado por fluido a presión, caracterizado por entrar en su composición, una conducción general cargada normalmente, un depósito auxiliar normalmente cargado, una comunicación de carga restringida y de disipación de sobrecarga normalmente abierta y uniendo el depósito auxiliar a la conducción general, un dispositivo de mando de carga susceptible a la acción del fluido a presión de ocupar una posición de cierre para formar dicha comunicación, un dispositivo susceptible de responder a una primera reducción de la presión de conducción general por debajo de su valor normal y completo, llevando a cabo un escape local de la conducción general para realizar una reducción "de ajuste rápido" en la presión de conducción general y dirigiendo el fluido que así sale hacia el dispositivo de mando de carga para colocar a éste en su posición de cierre, y un dispositivo capaz de responder a una reducción mayor que la primera reducción de la presión de conducción general poniendo fin a este escape local y dirigiendo el fluido del depósito auxiliar hacia el dispositivo de mando de carga para mantener a éste en su posición de cierre.
