Abstract (en)

[origin: US4741665A] A guide vane for turbo-engines has a stationary vane section and a movable vane section with a gap between the two sections. The gap is covered on one side by a flexible band connected along its tape edges to the vane sections. The other side of the gap is covered by an elastic connected to the stationary vane section along one band edge while the other band edge overlaps part of the movable vane section to permit free relative movement between the elastic band (7) and the movable vane section. A plurality of such guide vanes are mounted at the radially outer end of their position adjustment member to an outer housing ring while the radially inner vane end or at least the radially inner end of the movable vane is free. A common position adjustment ring is connected to all adjustment members.
