Abstract
A guide vane assembly, with at least one guide vane row and a housing for the at least one guide vane row that extends along a circumferential direction about a central axis. The at least one guide vane row comprises multiple guide vanes that are respectively mounted at the housing in an adjustable manner by means of an adjusting appliance of the guide vane assembly. The adjusting appliance comprises at least one adjusting element for adjusting the guide vanes that is arranged at a radial distance to an outer side of the housing with respect to the central axis. A compensation device is provided, via which a radial distance of the adjusting element to the outer side of the housing is predetermined, and the different thermal expansions of the adjusting element and of the housing are at least partially compensated for the purpose of maintaining these distances.
