The guide vanes are attached to the outer ring (2) in the region of the pivot points (25). The outer ring, at least in the swivel areas of the individual vanes, is constructed plane and perpendicular to the guide vanes. The blade ring is constructed as a polygonal ring in segmented form which has a number of segments each with one or more pivotable guide vanes.
