Abstract

L’invention concerne un ensemble de lubrification pour turbomachine comprenant une enceinte de lubrification (24), une chambre de pressurisation (26), et une pompe de récupération (16) de gaz et de lubrifiant. L’enceinte de lubrification (24) comprend une première entrée (21) de gaz sous pression, un premier joint d’étanchéité (31) à garniture déformable qui empêche du lubrifiant de sortir de l’enceinte de lubrification (24) à travers la première entrée (21), et une sortie de gaz et de lubrifiant qui est reliée à la pompe de récupération (16). L’ensemble de lubrification comprend une vanne de pressurisation (42) de l’enceinte de lubrification (24). La vanne de pressurisation (42) est configurée pour s’ouvrir lorsqu’une valeur de différence de pression (P2-P1) entre la chambre de pressurisation (26) et l’enceinte de lubrification (24) est supérieure à une valeur seuil.
