Abstract

L'invention se rapporte à une turbomachine d'aéronef à double flux comprenant un compartiment inter-veines (50) logeant un réservoir de lubrifiant (54), le compartiment inter-veines étant délimité extérieurement par un capot (52) délimitant intérieurement une veine secondaire (14b) de la turbomachine, le capot comportant un accès obturable (64) à un orifice déporté (74) de remplissage du réservoir de lubrifiant. La turbomachine comporte en outre : - un orifice d'évacuation de trop plein (82) situé plus bas sur le réservoir que l'orifice d'introduction de lubrifiant (68) ; - un conduit d'évacuation de trop plein de lubrifiant (84) cheminant vers le bas à partir de l'orifice d'évacuation de trop plein (82) ; - une vanne d'évacuation (88) commandée, associée à l'orifice d'évacuation de trop plein (82) ; et - un dispositif (90, 94) de commande de la vanne d'évacuation (88), le dispositif de commande étant accessible par l'accès (64).
