Abstract

In liquid cooled rotors of turbogenerators with half-turn cooling and cooling water feed at the dynamo side as well as cooling water discharge through a collecting chamber on the turbine side, the cooling water collecting chamber is arranged within the generator housing, axially immediately adjacent to the receiving chamber, and is sealed against the rotor shaft by labyrinth rings through which is provided, as a barrier, a flow of the cooling gas for the generator housing.
