Abstract

Raccord fluidique (30) pour une pièce de turbomachine, comportant : - un manchon tubulaire (32) comportant une première extrémité (32a) configurée pour être emboîtée dans ou sur une première pièce de turbomachine, et une seconde extrémité (32b) opposée configurée pour être emboîtée dans ou sur une seconde pièce de turbomachine, le manchon (32) comportant un passage interne (34) de circulation de fluide s’étendant depuis ladite première extrémité (32a) jusqu’à ladite seconde extrémité (32b), le manchon (32) comprenant en outre un filetage interne (36) dans ledit passage (34), et - un doigt de réglage (38) engagé dans ledit passage (34) et comportant un filetage externe (40) de vissage dans ledit filetage interne (36), le doigt étant apte être plus ou moins vissé dans le manchon (32) de façon à régler sa position dans le manchon le long d’un axe commun aux filetages (36, 40), les filetages définissant entre eux un chemin hélicoïdal (42) de passage de fluide. Figure pour l'abrégé : Figure 4Fluid connection (30) for a turbomachine part, comprising: - a tubular sleeve (32) comprising a first end (32a) configured to be fitted into or on a first turbomachine part, and an opposite second end (32b) configured to be fitted into or on a second turbomachine part, the sleeve (32) comprising an internal fluid circulation passage (34) extending from said first end (32a) to said second end (32b), the sleeve ( 32) further comprising an internal thread (36) in said passage (34), and - an adjustment finger (38) engaged in said passage (34) and comprising an external thread (40) for screwing into said internal thread (36) ), the finger being able to be more or less screwed into the sleeve (32) so as to adjust its position in the sleeve along an axis common to the threads (36, 40), the threads defining between them a helical path ( 42) for fluid passage.
