Abstract

<B>VáLVULA ACIONADA POR SOLENóIDE PARA SISTEMA DE FREIO DE TRENS DE CARGA CONTROLADO ELETRONICAMENTE<D>. Um dispositivo de válvula de freio acionada por solenóide para uso em um sistema eletrónico de controle de freio de trem de carga em um vagão ferroviário. Tal sistema de frenagem tendo uma tubulação de freio normalmente cheia de fluido a uma certa pressão, reservatórios auxiliar e de emergência de compartimentos separados cheios a uma certa pressão com fluido proveniente da tubulação de freio e um dispositiov de cilindro de freio acionado por pressão de fluido. O fluxo de fluido pressurizado proveniente dos reservatórios auxiliar e de emergência separados pode ser fornecido simultaneamente ao dispositivo de cilindro de freio por meio da válvula única de acionamento de freio. Válvulas de retenção de refluxo entre cada reservatório e a válvula de acionamento de freio impedem a transferência de fluido pressurizado entre os reservatórios. O controlador eletrónico pode operar a válvula de acionamento para controlar as funções de frenagem e de liberação responsivas a sinais elétricos de comando. Uma válvula de controle pneumático pode também ser operativamente incorporada ao sistema de controle de freio.<B> SOLENOID-ACTIVATED VALVE FOR ELECTRONICALLY CONTROLLED LOAD TRAIN BRAKE SYSTEM <D>. A solenoid-operated brake valve device for use in an electronic freight train brake control system in a railway car. Such a braking system having a brake line normally filled with fluid at a certain pressure, auxiliary and emergency reservoirs of separate compartments filled to a certain pressure with fluid from the brake line and a fluid pressure driven brake cylinder device . The flow of pressurized fluid from the separate auxiliary and emergency reservoirs can be supplied simultaneously to the brake cylinder device via the single brake actuation valve. Backflow check valves between each reservoir and the brake actuation valve prevent the transfer of pressurized fluid between the reservoirs. The electronic controller can operate the actuation valve to control the braking and release functions responsive to electrical command signals. A pneumatic control valve can also be operatively incorporated into the brake control system.
