Abstract
In previously known turbogenerators, the cooling-air chambers are included in the structural configuration of the generator casing. In order to avoid complex manufacturing processes, it is intended that the chamber be a box that is separate from the generator casing. The box has an opening on its side facing the built-in stator with an edge surface of the opening being fitted with a sealing element that acts with respect to the circumferential surface of the built-in stator. The box is connected to the built-in stator with the interposition of a rubber bearing.
