Abstract (en)
[origin: EP1696104A2] The device has an actuating ring connected to a variable guide vane by links (26), each with a radial finger and a mounting orifice (24). Each orifice has a size larger than that of a square spindle drive (22) of the vane so that a clearance is formed between them. The clearance is varied between a value, sufficient in the longitudinal direction of the link, and a low or nil value when each link is placed on the drive.
