Abstract
The control device comprises at least one control ring to which one end of n elbow lever is articulated. The vane pivot of alternating vanes is fixed at the intersection of the arms of the elbow levers. The other end of each elbow lever is connected by a rod to the end of a straight lever, the other end of which is fixed to the pivot of an adjacent vane. The circumferential movement of the ring causes the pivots of the adjacent vanes to pivot in opposite directions. Two other embodiments have two rings.
