Abstract

A device for deflecting at least a portion of a cooling fluid flowing axially in an intermediate space is arranged between a rotor and a stator of a rotating electrical machine, in particular of a turbogenerator, wherein at least one blade can be arranged on a prespecifiable section of an outer face of the rotor and in the intermediate space, which blade is designed and can be arranged in such a way that a portion of the cooling fluid flowing in the intermediate space can be radially deflected in the direction of the stator by said blade.
