Abstract

Circuit de carburant d'une turbomachine, ce circuit comprenant : - une vanne de retour carburant (FRV) reliée au circuit principal (102) de carburant et à un réservoir (110), la vanne (FRV) pouvant adopter une première et une deuxième position ouverte, distinctes, et une position fermée, - deux lignes hydrauliques primaires (120, 130) reliant la vanne (FRV) au circuit principal (102) et comprenant, respectivement, des premier et deuxième filtres (125, 135) à travers lesquels passe le carburant lorsque la vanne (FRV) est dans sa première position ouverte, - deux lignes hydrauliques secondaires (140, 150) qui relient la vanne (FRV) au circuit principal (102) et qui sont positionnées par rapport aux premiers filtres (125, 135) de telle sorte que la circulation de carburant dans ces lignes secondaires (140, 150) contribue, respectivement, au nettoyage des premier et deuxième filtres (125, 135), le carburant circulant dans les lignes secondaires (140, 150) lorsque la vanne (FRV) est dans sa deuxième position ouverte.
