Abstract

resumo patente de invenção: "circuito de carburante que compreende meios de controle de uma bomba". a presente invenção refere-se a um circuito de carburante (10) de uma turbomáquina que compreende uma bomba de baixa pressão (12), uma bomba de alta pressão (14), um conduto de baixa pressão (22) que liga a bomba de baixa pressão (12) à bomba de alta pressão (14), um conduto de alta pressão (26) alimentado pela bomba de alta pressão (14), no qual pelo menos um componente (20) é disposto, meios de controle do funcionamento do componente (20), caracterizado pelo fato de que ele compreende uma válvula automática (34) própria para obturar um segmento (30, 32) do conduto (26) quando a pressão do conduto de baixa pressão (22) é inferior a um valor limite predeterminado, e os meios de controle são próprios para detectar que a válvula automática (34) obtura pelo menos em parte o segmento (30, 32).
