Abstract

Equipo de frenado por fluido a presión, caracterizado porque comprende un canal susceptible de ser conectado a un conducto general, un depósito de mando para acumular el fluido a una presión dada, siendo utilizadas las variaciones de presión en el canal de conducto general con relación a esta presión dada para controlar el grado de frenado, una primera comunicación de carga para dirigir el fluido a presión al depósito de mando durante la carga inicial del equipo, un primer dispositivo de válvula que responde a la presión en el depósito de mando para cerrar la segunda comunicación de carga durante todo el tiempo en que la presión en el depósito de mando rebasa un cierto valor inferior a dicha presión dada ya mencionada.
