Abstract (en)
[origin: EP1820942A1] The device has a control ring (26) centred on a longitudinal axis of a turbo-engine. The control ring is provided with a set of tapped holes (36) running in a radial direction, and a set of pad holders (32) with a threaded rod (34) screwed into one of the tapped holes. Each pad holder holds a pad (30) intended to come into contact with a cylindrical shell (28) coaxial with the ring. The pads are adjusted in the radial direction by screwing the threaded rod into the control ring.
