Abstract

"DISPOSITIVO PARA LIBERAçãO". A invenção diz respeito a um dispositivo para liberação, de um tubo alimentador (10), de um agente redutor, que foi previamente convertido de uma primeira fase em uma segunda fase e, em seguida, de volta para a primeira fase, onde o tubo é usado para alimentar,o agente redutor na segunda fase a um catalisador SCR inserido na linha de descarga de um motor a diesel. O dispositivo é uma válvula (12) para dosagem do agente redutor na segunda fase. A sede fixa da válvula ou a face móvel da válvula (16) se encostando e apoiando na mesma, quando a válvula (12) se encontra na posição fechada, é na forma de um elemento condensador controlado por um controlador e previsto para atuar como um coletor criogênico inserido no tubo alimentador (10), quando controlado de maneira correspondente. O elemento condensador, ou o elemento de válvula unido ao mesmo, é aquecível sob controle de um controlador.
