PATENTANSPRÜCHE:PATENT CLAIMS: 1. Innengekühlte Turbinenschaufel, dadurch gekennzeichnet, daß das Kühlmittel längs der radialen Ausdehnung der Schaufel durch eine Anzahl übereinander angeordneter Kanäle in Strömungsrichtung des Arbeitsmittels austritt.1. Internally cooled turbine blade, characterized in that the coolant along the radial extent of the blade through a number of channels arranged one above the other in the direction of flow of the work equipment leaks. 2. Innengekühlte Turbinenschaufel nach Anspruch 1, gekennzeichnet durch eine aus Blech gebogene Schaufel, dessen Endteile auf der Innenseite derart mit Nuten versehen sind, daß diese Nuten beim Aufeinanderbringen der Endteile die Kanäle zum Austritt des Kühlmittels bilden.2. Internally cooled turbine blade according to claim 1, characterized by one of Sheet metal bent blade, the end parts of which are provided with grooves on the inside are that these grooves form the channels for the exit of the coolant when the end parts are brought onto one another. 3. Innengekühlte Turbinenschaufel nach Anspruch 1 und 2, dadurch gekennzeichnet, daß die Schaufel statt aus einem glatten Blech mit auf der Innenseite eingearbeitetem Nuten aus einem gewalzten Blech gefertigt ist, dessen Innenseite mit Erhöhungen nach Art eines Riffelbleches versehen ist.3. Internally cooled turbine blade according to claim 1 and 2, characterized in that the blade is made from a rolled sheet instead of a smooth sheet with grooves incorporated on the inside, the inside of which is provided with elevations in the manner of a corrugated sheet. 4. Innengekühlte Turbinenschaufel nach Anspruch 1, 2 oder 3, dadurch gekennzeichnet, daß die aufeinanderstoßenden Stege oder Erhöhungen der Endteile der Bleche bzw. der Schaufeln miteinander beispielsweise durch Punktschweißung verbunden sind.4. Internally cooled turbine blade according to claim 1, 2 or 3, characterized in that that the abutting webs or elevations of the end parts of the metal sheets or the blades with one another for example connected by spot welding.
