CA 2418356

A spring (15) of angular shape is placed between the lug (17) of a connecting rod (10) controlling the orientation of a stator blade and the pivot (3) of said blade, such that its edge (18) bends against one edge face (19) of the connecting rod (10) and the washer (16) moves the pivot (3) in the play of the bore (21) of the connecting rod and sets and maintains the contact between two plane faces (12 and 13), so as to reduce the differences in angular displacements between the connecting rod and pivot due to the play remaining in the bore (21).

Un ressort (15) de forme angulaire est placé entre la patte (17) d'une bielle d'accouplement (10) qui commande l'orientation d'une aube de stator et du tourillon (3) de ladite lame, de telle sorte que son bord (18) se plie contre une face latérale (19) de la bielle d'accouplement (10) et que la rondelle (16) fait déplacer le tourillon (3) dans le jeu de l'alésage (21) de la bielle d'accouplement et établit et maintient le contact entre deux faces planes (12 et 13), de manière à réduire les différences dans les déplacements angulaires entre la bielle d'accouplement et le tourillon à cause du jeu restant dans l'alésage (21).
