Abstract

L’invention concerne une turbomachine (1, 1’, 1’’) comprenant un système d’alimentation en huile (14) comprenant : un réservoir principal (15) d’huile, une pompe d’alimentation (18) comprenant une entrée (18a) et une sortie (18b) reliée au système de commande (13), un réservoir auxiliaire (20) d’huile, et une vanne (21) présentant une première entrée (21b) reliée au réservoir principal (15), une seconde entrée (21c) reliée au réservoir auxiliaire (20) et une sortie (21d) reliée à l’entrée (18a) de la pompe d’alimentation (18), la vanne (21) comprenant en outre un organe mobile dans le corps (21a) et configuré pour se déplacer entre une première position dans laquelle la première entrée (21b) de la vanne (21) est en communication fluidique avec la sortie (21d) de la vanne (21) et une seconde position dans laquelle la seconde entrée (21c) de la vanne (21) est en communication fluidique avec la sortie (21d) de la vanne (21). Figure d’abrégé : 4The invention relates to a turbomachine (1, 1', 1'') comprising: an oil supply system (14) comprising: a main oil tank (15), a feed pump (18) comprising an inlet (18a) and an outlet (18b) connected to the control system (13), an auxiliary oil tank (20), and a valve (21) having a first inlet (21b) connected to the main tank (15), a second inlet (21c) connected to the auxiliary tank (20) and an outlet (21d) connected to the inlet (18a) of the feed pump (18), the valve (21) further comprising a movable member in the body (21a) and configured to move between a first position in which the first inlet (21b) of the valve (21) is in fluid communication with the outlet (21d) of the valve (21) and a second position in which the second inlet (21c) of the valve (21) is in fluid communication with the outlet (21d) of the valve (21).
