Abstract

<B>VáLVULA DE FREIO ELETROPNEUMáTICO DE ESTRADA DE FERRO E MéTODO DE EMULAçãO<D> Uma válvula de controle de freio eletropneumática para realizar emulação eletrónica é fornecida em que válvulas eletrónicas múltiplas controlam operações de frenagem em vagões ferroviários. Múltiplos sensores de pressão são preferivelmente utilizados, e particularmente um sensor de pressão de tubo de freio para detectar comandos de freio pneumático. Além de utilizar válvulas eletrónicas para controlar operações de aplicação e liberação de freio, uma válvula de serviço rápido eletrónica pode descarregar seletivamente o tubo de freio de descarga na atmosfera em uma taxa e quantidade controladas para auxiliar a propagação de uma aplicação de serviço rápido e uma válvula de liberação acelerada eletrónica pode conectar seletivamente o reservatório de emergência ao tubo de freio para auxiliar a recuperar a pressão de tubo de freio e na propagação de uma liberação direta dos freios. A válvula de controle eletropneumático também inclui preferivelmente um microprocessador para sinal e interpretação de comando e controle de válvula.
