Abstract
A system for controlling two stages of variable-pitch stator vanes of a turbomachine, the system comprising a drive element for turning the control ring of one of the stages via a leader member pivotally mounted on the casing, a synchronization bar for transmitting the turning movement of the ring driven by the drive element to the control ring of the other stage via a follower member pivotally mounted on the casing, and an additional pivot member interposed between the follower member and the follower ring, said additional pivot member being pivotally mounted both on the casing and on the follower member.
