Abstract

L'invention concerne un procédé de lubrification et de refroidissement d'organes mécaniques (16) répartis dans des enceintes pressurisées (E1-E3 ) d'une turbomachine (2), comprenant le prélèvement de carburant dans un circuit de carburant (100) de la turbomachine en aval d'une pompe haute-pression (112) dudit circuit de carburant, l'injection du carburant prélevé dans les enceintes de la turbomachine pour lubrifier et refroidir les organes mécaniques exclusivement au moyen du carburant injecté, la récupération en sortie des enceintes du carburant ayant servi à la lubrification et au refroidissement des organes mécaniques, et la réintroduction du carburant récupéré dans le circuit de carburant de la turbomachine.
