Abstract
The steam turbine has an interior chamber through which an action steam can flow. The action steam is condensed in a condenser. The condenser is connected to the interior via a cooling-steam conduit. The cooling-steam conduit can be shut off by means of a shut-off member which opens as a function of the differential steam pressure between the condenser and the interior. The method of cooling the steam turbine is effected by cooling the steam turbine with steam from the condenser in the ventilation mode of the turbine.
