Abstract

MONTAGEM DE BOMBA DOSADORA PARA MISTURAR UM AGENTE DE FLUIDO DE REDUçãO EM FLUXO DE GáS DE EXAUSTãO. Refere-se a uma montagem de bomba dosadora para misturar um agente de redução de fluido em um fluxo de gás de exaustão, que compreende um dispositivo de pré-miscura (39) no qual o agente de redução fornecido é misturado em uma região de mistura (18) com um gás pressurizado, onde uma primeira válvula de retorno (20) é arranjada no elemento de pré-mistura (39) em um conduto de fornecimento (15) para o agente de redução, em frente à região de mistura (18) na direção do fluxo.
