Abstract

L'invention concerne un dispositif d'alimentation en lubrifiant. Le dispositif comporte une chambre tournante contenant une quantité limitée de lubrifiant de manière que, en cas de coupure de l'alimentation en lubrifiant du dispositif, du lubrifiant contenu dans ladite chambre soit refoule par centrifugation vers le composant à lubrifier en vue de maintenir une lubrification continue mais limitée. Application aux groupes propulseurs d'avions.
