Abstract

Instalación de frenado por fluido a presión , caracterizada porque comprende un conducto general, un cilindro de freno, una comunicación de regulación de admisión del fluido en el cilindro de freno, un dispositivo de válvula 6 mandado por la presión en el conducto general y por una presión opuesta y susceptible, a consecuencia de una reducción de la presión en el conducto general con relación a dicha presión opuesta, de establecer una comunicación de apretamiento rápido para hacer escapar el fluido a presión fuera del conducto general, un depósito de mando 4, un dispositivo 5 de válvula sensible a la caida de presión en una cámara para establecer una comunicación entre el conducto general y el depósito de mando con el fin de cargar este depósito con fluido procedente del conducto general, siendo dicho medio de válvula susceptible por otra parte de cerrar esta comunicación bajo la acción de al presión que reina en dicha cámara, y un dispositivo de válvula 8 de regulación de la admisión en el cilindro de freno mandado por la presión en el cilindro de freno y susceptible, cuando esta presión es inferior a un valor elegido de conectar dicha comunicación de apretamiento rápido a dicha cámara u de conectar dicha comunicación de regulación de admisión al cilindro de freno, siendo igualmente susceptible este último dispositivo de válvula de regulación de admisión, cuando la presión en el cilindro de freno rebasa un valor elegido, de cortar la comunicación de apretamiento rápido y la comunicación de regulación de admisión.
