Abstract

Un activador de freno neumático tiene un activador de freno de resorte con cámaras de resorte y presión de freno de resorte, y un activador de freno de servicio con cámaras de presión de freno de servicio y de varilla de empuje; una válvula de control tiene un sello que se puede mover entre una posición abierta y una posición cerrada para regular el flujo de fluido entre la cámara de resorte y la cámara de presión de freno de servicio; una primera superficie del sello está en comunicación de fluido con la cámara de presión del freno de servicio y una segunda superficie en comunicación de fluido con una cámara de válvula que no está en comunicación de fluido con la cámara de presión de freno de servicio o la cámara del resorte; el sello se mueve entre sus posiciones abierta y cerrada con base en una presión en la cámara de presión de freno de servicio; el movimiento del sello no depende del índice de flujo de fluido entre la cámara del resorte y la cámara de presión del freno de servicio.
