Abstract

Système de commande de deux étages (10, 10') d'aubes de stator (14, 14') à angle de calage variable de turbomachine, comportant un élément de manoeuvre (24) pour entraîner en rotation l'anneau de commande (22) de l'un des étages (10) par l'intermédiaire d'un organe pilote (26) monté de façon pivotante sur le carter (12), une barre de synchronisation (30) pour transmettre le mouvement de rotation de l'anneau entraîné (22) par l'élément de manoeuvre (24) à l'anneau de commande (22') de l'autre étage (10') par l'intermédiaire d'un organe suiveur (26') monté de façon pivotante sur le carter, et un organe pivotant supplémentaire (44) intercalé entre l'organe suiveur (26') et l'anneau suiveur (22'), ledit organe pivotant supplémentaire étant monté de façon pivotante sur l'organe suiveur (26') et relié au carter (12) par un galet (46) coulissant dans une rainure (48) solidaire du carter.
