Abstract

La presente invención se refiere a un sistema para mantener presión en un cilindro de freno, caracterizado porque comprende: un conducto del cilindro de freno configurado para estar en comunicación fluida con un cilindro de freno; un conducto de tubo de freno configurado para estar en comunicación fluida con un tubo de freno y un cilindro de freno; un primer miembro de válvula movible entre una primera posición y una segunda posición; un segundo miembro de válvula en comunicación fluida con una presión de referencia, el segundo miembro de válvula configurado para mover el primer miembro de válvula desde la primera posición a la segunda posición en base a un diferencial entre una presión dentro del conducto del cilindro de freno y la presión de referencia, en donde cuando el primer miembro de válvula está en la segunda posición, el conducto de tubo de freno está configurado para suministrar aire directamente desde un tubo de freno a un cilindro de freno.
