A lubrication system for lubricating gas turbine engine components and accessory components separately comprises first and second lubricant circulating circuits for separately feeding lubricant to the engine components (26) and the accessory components (28). The system further includes a supply tank (30) with first and second separate chambers (32, 34) respectively connected in fluid flow communication with the first and second lubricant circulating circuits (26, 28). A filler port (38) is defined in the tank (30) for allowing the first chamber (32) to be filled with lubricant. A filling and level maintaining circuit (40) is connected to the first lubricant circulating circuit (26) for directing a portion of the lubricant fluid pumped from the first chamber (32) into the second chamber (34), thereby obviating the need for a second filler port.

L'invention concerne un système de lubrification utilisé pour la lubrification de composants d'un moteur à turbine à gaz et, séparément, de composants accessoires, système comprenant un premier et un second circuits de circulation de lubrifiant destinés à alimenter séparément en lubrifiant les composants du moteur et les composants accessoires. Le système comprend en outre un réservoir d'alimentation comportant une première et une seconde chambres séparées, en communication avec écoulement de fluide, respectivement, avec le premier et le second circuits de circulation de lubrifiant. Il est prévu un orifice de remplissage dans le réservoir, permettant de remplir la première chambre en lubrifiant. Un circuit de remplissage et de maintien du niveau est relié au premier circuit de circulation de lubrifiant, en vue de diriger dans la seconde chambre une partie du fluide lubrifiant pompé de la première chambre, ce qui évite d'avoir un second orifice de remplissage.
