Abstract

circuito de alimentação de combustível e motor de aeronave. a invenção refere-se a um circuito de alimentação de combustível (10) de um motor de aeronave, comportando um sistema de bombeamento de alta pressão (18) tendo uma primeira e uma segunda bombas volumétricas (18a, 18b), um atuador hidráulico (200) e um dosador de combustível (100), em função da posição de uma gaveta (202) do atuador, o orifício de alimentação (ao) do mesmo pode ser ligado ao orifício de utilização de alta pressão (lj1) ligados à saída (40b) da segunda bomba (18b) ou ao orifício de utilização de baixa pressão (u2) ligado a uma linha de alimentação de baixa pressão (20). o dosador de combustível é munido de seções de passagem, uma destas seções de passagem (114) sendo ligada entre elas à sída do sistema de bombeamento de alta pressão, e a outra seção de passagem (116) sendo ligada à saída do sistema de bombeamento de alta pressão e se abrindo em uma câmara de alta pressão de pitolagem (p1) do atuador hidráulico.
