da die Einschaltung von Zwischenmechanismen die Regelung erschweren würde.
Eine Ausführungsform der Erfindung zeigt Fig. l. Mit der Turbinenscheibe a ist ein Kolben b fest verbunden, der aussen mit Labyrinthdichtung gegen das Gehäuse abschliesst. Die dem Turbinenrade zugewandte Seite des Kolbens steht unter dem Drucke des aus dem Düsenring ausströmenden Dampfes ; die andere Seite bildet die Wand eines Raumes e, der durch ein Rohr

Abschlussorgan d, e, dessen Sitz am Gehäuse, dessen Teller an der Welle befestigt ist. Je nach der Stellung der Welle wird das Abschlussorgan d, e mehr oder weniger verengt. In dem Räume c wird sich nun ein solcher Druck einstellen, dass sich alle Axialdrücke das Gleichgewicht halten.
Fig. 2 zeigt eine andere Anordnung. Ein Teil der Radscheibe selbst ist als Gegendruck- tliiche benutzt. Eine mit dem Laufrade fest verbundene Labyrinthdichtung trennt den Auspuff-

Vorteilhaft wird auf der Welle noch ein als Katarakt wirkender Kolben befestigt, welcher plötzlich auftretende Druckschwankungen aufnimmt.

since the involvement of intermediate mechanisms would make the regulation more difficult.
An embodiment of the invention is shown in FIG. A piston b is firmly connected to the turbine disk a and closes against the housing on the outside with a labyrinth seal. The side of the piston facing the turbine wheel is under the pressure of the steam flowing out of the nozzle ring; the other side forms the wall of a room e covered by a pipe

Closing element d, e, its seat on the housing, the plate of which is attached to the shaft. Depending on the position of the shaft, the closing organ d, e is narrowed more or less. In the space c there will now be such a pressure that all axial pressures are in equilibrium.
Fig. 2 shows another arrangement. Part of the wheel disc itself is used as a counter pressure table. A labyrinth seal firmly connected to the impeller separates the exhaust
EMI1.5
Space that is connected to the steam supply line through line f. The valve and thus the shaft will adjust itself in such a way that the steam escaping through the seal is continuously replaced by live steam and that the required counter pressure is maintained in space c @.
A piston acting as a cataract is advantageously attached to the shaft and absorbs sudden pressure fluctuations.
