Abstract

Le circuit de lubrification comprenant un réservoir d'huile (4) intégré à une première enceinte lubrifiée (5) comprend, sur une conduite (10) de récupération originaire des enceintes lubrifiées du circuit menant au réservoir (4), un conduit d'évacuation (20) qui s'ouvre vers un exutoire (21) quand une pression excessive dans le réservoir, symptôme d'un remplissage progressif, est atteinte. Application aux circuits de lubrification des moteurs d'aéronefs, notamment pour se prémunir de fuites de carburant dans le lubrifiant par un échangeur de chaleur défectueux.
