Abstract

L’invention concerne un module (3) d’axe longitudinal (X) et comprenant un actionneur hydraulique (46), et une pompe (54) d’alimentation en fluide de l’actionneur hydraulique (46) comprenant des pistons axiaux (54c) destinés à être mobiles en rotation autour de l’axe longitudinal (X) et configurés pour transférer le fluide à l’actionneur hydraulique (46), un plateau de liaison (54g) relié aux pistons axiaux (54c) et coopérant avec un plateau principal (54e) annulaire centré sur l’axe longitudinal (X), destiné à être fixe en rotation autour de l’axe longitudinal (X) et inclinable par rapport à l’axe longitudinal (X), le plateau de liaison (54g) étant agencé entre le plateau principal (54e) et les pistons axiaux (54c), les pistons axiaux (54c) étant mobiles en translation selon une direction (D) parallèle à l’axe longitudinal (X), l’inclinaison du plateau principal (54e) entraînant un déplacement des pistons axiaux (54c) selon la direction (D).
