Abstract
A device for sealing between the guide vanes ( ) and the rotor ( ) of turbomachines, especially gas turbines has inner rings ( ) suspended on the vane footing ( ) of the guide vanes ( ) in a thermally elastic manner with soldered honeycomb seal ( ) and labyrinth tips ( ) arranged on the rotor ( ). First flow channels, which are connected to the cavities ( ) of the cooled guide vanes ( ), through which said cavities cooling air flows, are led through the vane footings ( ). The first flow channels are connected to at least one of second flow channels led through the inner ring ( ) to the vicinity of the honeycomb seal ( ). The second flow channels open into at least one of third flow channels that are open at the rear edge of the inner ring ( ) or are led to an annular groove ( ) open toward the honeycomb seal ( ) on the underside of the inner ring ( ).
