Abstract

G icleur de liquide lubrifiant à débit limité L’invention concerne un gicleur (G) pour lubrifier une pièce d’une turbomachine pour un aéronef tel qu’un d’avion, comprenant un conduit de circulation destiné à l’écoulement d’un fluide sous pression, ainsi que : une première chambre de conduit (1), une deuxième chambre de conduit (2), un premier ajutage (12) de passage entre la première chambre de conduit (1) et la deuxième chambre de conduit (2), le premier ajutage ayant une section minimale de passage fixe, et un deuxième ajutage (23) de passage de la deuxième chambre à l’orifice de sortie formée par le deuxième ajutage (23), le deuxième ajutage comprenant une section minimale de passage fixe. Le ratio de la section du premier ajutage (12) sur la section du deuxième ajutage (23) est compris entre 0.16 et 3.61. (Figure de l’abrégé: Figure 2)
