Abstract
A guide vane adjusting device for rotating guide vanes in a guide vane assembly having a driveshaft and a control ring that transmits a driveshaft rotation of the driveshaft to rotate the guide vanes. Each guide vane has a front and a rear vane part, which can be rotatable relative to each other about a respective guide vane rotational axis. The driveshaft is directly coupled to one of the guide vanes such that the vane parts are directly rotated without the interposition of the control ring. The driveshaft is indirectly coupled to the other guide vanes such that the guide vane parts are rotated indirectly with the interposition of the control ring. A respective drive lever acts on a bearing pin of the front vane part and a bearing pin of the rear vane part of the guide vane. The drive lever are coupled together via a respective coupling device.
