Abstract

Patente de Invenção: <B>" BOMBA DE ALIMENTAçãO EM CARBURANTE COMANDADA ELETRICAMENTE, PARA MOTOR DE COMBUSTãO INTERNA"<D>. O circuito compreende uma bomba (1) de motor elétrico que bombeia carburante em um reservatório (3) de carburante, e que alimenta uma rampa (8) de injetores (9) com a assistência de um regulador (7) de pressão de carburante. O motor da bomba (1) é comandado por uma unidade (4) de comando para alinhar a pressão de saída da bomba (1), avaliada por uma relação entre essa pressão e pelo menos a corrente média do motor da bomba (1), em uma pressão objetiva determinada pela unidade de comando (4) e escolhida superior à pressão de funcionamento do regulador (7), do tipo detentor, e cuja característica de pressão é conhecida pela unidade de comando (4). Aplicação para a alimentação em carburante dos motores de injeção, direta ou indireta, de veículo automóvel.
