Abstract

L’invention concerne un circuit d’huile (38) pour une turbomachine (10) d'aéronef comportant au moins une boucle (40) de circulation d'huile comportant successivement au moins un réservoir d'huile (42), une pompe d'alimentation (44), un échangeur huile / carburant (46), au moins une enceinte d'huile (34, 36) définie par au moins un rotor tournant dans un carter et alimentée en air pressurisé, et au moins une pompe de refoulement (48) assurant un retour d'huile au réservoir (42), caractérisé en ce qu'il comporte un dispositif de décharge (50) qui est configuré pour s'ouvrir en réponse au dépassement d'un seuil de pression déterminé dans ladite boucle dans une plage de températures de fonctionnement nominales du moteur. Figure pour l'abrégé : Figure 3.The invention relates to an oil circuit (38) for an aircraft turbomachine (10) comprising at least one oil circulation loop (40) successively comprising at least one oil reservoir (42), an oil pump. supply (44), an oil / fuel exchanger (46), at least one oil chamber (34, 36) defined by at least one rotor rotating in a housing and supplied with pressurized air, and at least one delivery pump (48) providing an oil return to the reservoir (42), characterized in that it comprises a discharge device (50) which is configured to open in response to the exceeding of a determined pressure threshold in said loop within a range of rated engine operating temperatures. Figure for the abstract: Figure 3.
