Abstract
Perfeccionamientos en válvulas de mando para instalaciones de frenos de aire comprimido para vehículos ferroviarios, con un émbolo cargado por la presión en un conducto de aire principal contra la presión en una cámara de mando, para el accionamiento de una válvula de entrada y salida para poner bajo presión a un cilindro de freno, y con una válvula de aceleración para la toma de aire de un conducto de aire principal a una cámara cuya comunicación a la atmósfera está controlada por una válvula gobernada por la presión en el cilindro de freno, y con un dispositivo de control que controla la comunicación conducida sobre una tobera de sensibilidad desde el conducto del aire principal a la cámara de mando, accionado por un émbolo que está bajo la presión de la cámara y en contra de la presión del conducto de aire principal, caracterizados porque el dispositivo de control presenta una válvula de cierre dispuesta en el enlace desde el conducto de aire principal a la cámara de mando que se abre sólo al ser predominante la impulsión del émbolo por la presión del conducto de aire principal, y por un dispositivo de bloqueo que al estar abierta la válvula de cierre, abre una comunicación estrangulada, desde el conducto de aire principal a la cámara.
