Abstract
To improve wall cooling, especially at gas turbine elements, such as buckets or blading, combustion chambers, infeed channels and so forth, it is proposed to arrange a partition wall between an outer plate and an inner plate, for instance formed of sheet metal. The partition wall forms a cooling agent chamber and a pressure equalization chamber. The partition wall preferably consists of a buckle plate whose bulges or protuberances are connected, as by welding, with the outer plate. There is maintained within the pressure equalization chamber a pressure which approximately corresponds to the hot gas pressure at the outer surface of the outer plate, so that there are avoided so-called boiler stresses.
