Abstract

Dispositif (1) comprenant un réservoir (2) de lubrifiant en communication avec une aspiration d’une pompe, une unité de commande de ladite pompe et une sortie (6) dudit lubrifiant sous pression associée, par l’intermédiaire d’une ligne sous pression (8), à un refoulement de ladite pompe ; l’unité est interfacée avec un capteur de pression associé à ladite ligne (8) pour lire la valeur de la pression du lubrifiant à l’intérieur de cette ligne, la ligne (8) prévoyant une ligne de dérivation (9) aboutissant dans le réservoir et interceptée par une vanne (11), la vanne (11) étant mobile entre une position de fermeture de ladite ligne de dérivation en l’isolant de la ligne sous pression (8) et une position d’ouverture mettant en communication les deux lignes, la vanne (11) étant associée à une partie mobile (15A) d’un actionneur commandé par ladite unité.
