Abstract

Perfeccionamientos en sistemas de freno de vehículos por fluido a presión, caracterizados porque comprenden una válvula relé de urgencia para mandar la aplicación de la presión desde una fuente de presión a las cámaras de freno en relación con las variaciones de presión en una tubería de servicio y eficaz para establecer la aplicación de esta presión desde dicha fuente a las dichas cámaras de freno en relación con la reducción de presión en una tubería de urgencia hasta un determinado valor, compuesto de un cuerpo, una válvula y pistón relé combinados móviles en dicho cuerpo, en relación con las variaciones de presión en dicha tubería de servicio, en una dirección para conectar dicha fuente y cámaras de freno, y en dirección opuesta para conectar dichas cámaras de freno a la atmósfera, un pistón de urgencia en dicho cuerpo sometido constantemente a la presión de la tubería de urgencia y medios elásticos para mover dicho pistón de urgencia y dicha válvula y pistón relé combinados en dicha una dirección cuando la presión en la tubería de urgencia baja hasta un valor predeterminado.
