Definitions

  • the invention proposes to use a known per se cooling hole in the stud used for the screw, which is supplied on the one hand with a vapor located in the flow channel and on the other hand connected via adekanalauslass with the Strömungskanalabdampfraum.
  • the vapor from the flow channel has a higher pressure than the vapor in the Strömungskanalabdampfraum, so that a forced flow through the cooling channel in the stud has resulted, resulting in a cooling of the screw as a whole.
