Abstract

The invention concerns a cooling mechanism for a steam turbine (1) which envisages in the area of the valve connection (40) a cooling channel (37) into which cooling steam flows from the flow channel (9) the steam then being fed as cooling steam in the area of the thrust balance piston (4).
