Abstract
L'invention concerne un circuit hydraulique (10) de turbopropulseur d'aéronef comportant un réservoir (16) de fluide hydraulique, une pompe (14), un composant (12) qui est alimenté en fluide sous pression par la pompe (14) et qui est mis en fonctionnement de manière sélective, et un circuit de recirculation (20) de fluide reliant la sortie de la pompe (14) avec le réservoir (16) caractérisé en ce qu'il comporte une soupape (22) arrangée dans le circuit de recirculation (20), qui est apte à obturer le circuit de recirculation (20) lorsque le composant (12) n'est pas mis en fonctionnement et qui est apte à ouvrir le circuit de recirculation (20) lorsque le composant (12) est mis en fonctionnement.
