Abstract

- Dispositif d'alimentation et de répartition de fluide. - Le dispositif (18) est destiné à alimenter un actionneur tournant à déplacement linéaire apte à commander le pas des pales d'une hélice, selon des domaines de fonctionnement distincts, à partir d'un ensemble de puissance rotatif. Selon l'invention, il est agencé pour être situé entre l'ensemble de puissance et l'actionneur, selon un axe longitudinal (A), en étant lié en rotation à ceux-ci, et comporte des moyens d'alimentation (20) en fluide coopérant avec ledit ensemble de puissance et définissant autant d'alimentations qu'il y a de domaines de fonctionnement de l'actionneur, un répartiteur de fluide (21) auquel sont raccordées lesdites alimentations et ayant des canaux séparés pour acheminer le fluide en direction de l'actionneur selon les domaines de fonctionnement, par le biais d'un équipement tubulaire (25) relié au répartiteur.
