Abstract

A device for controlling variable-pitch blades in a turbomachine compressor, including at least one control ring surrounding an external casing of the compressor, and a control shaft connected to the ring and to the rod of an actuator, the body of which is mounted such that it can pivot about an axle borne by a support mechanism of the control shaft so as to guarantee a precise relative positioning of the axis of pivoting of the actuator with respect to the control shaft.
