Combustion chamber shaft which is designed as a double casing and which, as seen in the top view, is circumferentially closed and is designed to be preferably essentially rectangular and is formed by inner and outer walls which are sealingly connected to one another in the upper and lower region and between which there is a cavity capable of being connected to lines via an inflow and an outflow connection. In order to achieve a high degree of rigidity in such a combustion chamber shaft, the inner wall 4 and outer wall 5 are provided with beads 17, the bottoms 18 of which rest one against the other and in the region of which the inner wall 4 is additionally connected to the outer wall 5. <IMAGE> |
