Abstract

L'invention concerne un système de pompe à carburant (100) et un procédé associé d'alimentation en carburant, depuis une source de fluide (112) associée, pour une ou des utilisations en aval (102, 104) associées comprenant (i) un mode de démarrage, (ii) un mode de marche, et (iii) un mode d'actionnement du moteur. Le système comporte une pompe (110) comprenant un étage primaire (116) ayant une entrée (114), et une sortie (120) qui est configurée pour fournir sélectivement un écoulement sous pression pour le (ii) mode de marche, et un étage de régénération (130) entraîné communément avec l'étage primaire (116) pour fournir sélectivement du fluide sous pression pour le (i) mode de démarrage et le (iii) mode d'actionnement. Figure pour l’abrégé : Fig. 1
