Abstract
An angular pitch control ring () of stator vanes (), the rotations of which are controlled by a mechanism () applying a thrust tangent to the ring (), is also moved in translation when it is displaced, making it touch the stator (). According to the invention, one lateral region () on one side of the mechanism () is constructed to be stiffer than the other region to take account of the larger forces that the mechanism () must apply in a direction of movement. Application to turbomachines.
