Abstract
Vibration damping guide vane ring assembly of an axial flow turbomachine, including mutually adjacent guide vanes, individual cover plates each being rigidly connected to a respective guide vane forming a cover band of the guide vane ring, the cover plates being frictionally connected to each other and the cover plates of the adjacent guide vanes having wedge-shaped recesses formed therein between the cover plates, and wedge-shaped damping elements having surfaces and being movably inserted in the recesses, each of the wedge-shaped damping elements exerting a vibration damping pressure on the respective cover plates through the surfaces of the damping elements in response to an axial pressure difference across the guide vane ring.
