Abstract

"CONJUNTO INJETOR DE COMBUSTìVEL PARA MOTOR DE COMBUSTãO". A presente invenção refere-se ao conjunto injetor de combustível que apresenta uma bomba alimentadora (10), pela qual combustível é alimentado de um recipiente de reserva de combustível (12) até uma bomba de alta pressão (18), sendo que pela bomba de alta pressão (18) é transportado combustível para um depósito (24), com o qual está ligado ao menos um injetor (26), pelo qual combustível é injetado no motor de combustão. Entre a bomba alimentadora (10) e a bomba de alta pressão (18) está integrado um filtro de combustível (20), estando previsto um refluxo (60) para combustível ao menos de um injetor (26) e/ou do depósito (24) até uma região de baixa pressão. No refluxo (60) está integrado um outro filtro de combustível (62), e o refluxo (60) desemboca a jusante do filtro de combustível (20) na conexão (16) entre a bomba alimentadora (10) e a bomba de alta pressão (18).
