Abstract
L’invention concerne un système de lubrification (100) pour une turbomachine qui comporte un réducteur (152). Le système de lubrification (100) comprend une branche principale (120) et une branche de dérivation (140) qui est agencée en parallèle de la branche principale (120). La branche principale (120) comprend un échangeur thermique (121, 122, 124). La branche de dérivation (140) comporte une résistance hydraulique qui est inférieure à la résistance hydraulique de la branche principale (120). Le réducteur (152) est situé en aval de la branche principale (120) et de la branche de dérivation (140). Le système de lubrification (100) comprend au moins un dispositif de dérivation (200) qui est configuré pour alimenter la branche de dérivation (140) en lubrifiant lorsqu’une valeur de pression du lubrifiant est inférieure à une valeur seuil.
