Abstract (en)

The rotor shaft has a radial circulating groove (12) providing a cavity (13). The groove is in fluidic connection, for the purpose of the supply and discharge of a cooling agent, on the one hand, with a cooling agent supply line (10) and, on the other hand, with a cooling agent discharge line (11). An independent claim is also included for the method for the partial cooling of a shaft of a rotor of a turbo-machine e.g. a steam turbine or gas turbine.
