Abstract
A device for controlling variable-pitch vanes in a turbomachine comprises links connecting the radial pivots of the vanes to radial fingers carried by semicircular elements and bridges of a control ring, the links being mounted in ball-and-socket manner on the radial fingers which are fixed to the control ring. This form of mounting enables all the vanes associated with the control ring to be set to the same angular pitch.
