Abstract
Circuit permettant l'alimentation en huile des paliers pendant les périodes de fonctionnement en gravité négative et les périodes au cours desquelles le moteur fonctionne dans une position retournée. Il comprend un réservoir de lubrification principal 30, une pompe d'alimentation 39, des canalisations de distribution 92, 18, 31 conduisant l'huile aux paliers 12, 26, des canalisations de retour 24, et une pompe de vidange 41 et un circuit auxiliaire qui comporte un réservoir d'huile hydraulique sous pression 35 et une conduite auxiliaire de lubrification 76 comportant un clapet de retenue 74 qui s'ouvre lorsque la pression disparait dans le circuit de lubrification principal. Application aux moteurs à turbine à gaz d'avions.
