   Gemäss der Erfindung ist hiebei die   Beschaufelung   so   geformt,   dass die   abgeteilt" ! !, durch   die Turbine strömenden Dampfringlagen bezüglich der inneren Teile eine   grössere Ausdehnung erfahren   als die   äusseren   Teile.

   Aus den Fig. 2 und 3 ist ersichtlich, dass die Austrittswinkel des ipperen Laufkranzes der Laufschaufeln 11 (Fig. 3) dieselben sind, wie die Anstrittswinkel des äusseren Laufradkranzes der Laufschaufeln 11 (Fig. 2). Die Geschwindigkeit des aus dem inneren Laufkranz austretenden Dampfes ist

 schaufeln 11   (Fig. 4).   Die Geschwindigkeit des den inneren Kranz der Laufschaufeln 11 verlassenden Dampfes ist daher auch hier grösser als die des aus dem äusseren Kranz derselben Schaufeln 11 austretenden Dampfes, weil einmal die   Umfanggeschwindigkeit   des inneren Kranzes kleiner ist und zweitens die inneren

   Bei Schaufeln dieser Ausführungsform nach Fig. 4 und   Ï   werden vorteilhaft die in der Fig. 1 punktiert angedeuteten   Trennringe     7.'2 und 13 angeordnet, obgleich   der Ring   1 : J in   den Laufschaufeln in manchen Fällen auch entfallen kann.

 sondern auch bei Ausführungsformen. bei denen der Dampf in drei oder mehrere   Ringlagen   zerlegt wird. Die restliche Energie des aus dem inneren Kranz von Laufschaufeln austretenden Dampfes kann auch stufenweise in zwei oder mehr aufeinanderfolgenden Schaufelrädern, statt wie dargestellt. nur in einem nutzbar gemacht werden.

 wreath go to the exhaust.



   According to the invention, the blading is shaped in such a way that the separated steam ring layers flowing through the turbine experience a greater expansion with respect to the inner parts than the outer parts.
 EMI1.2
 



   It can be seen from FIGS. 2 and 3 that the exit angles of the outer running ring of the rotating blades 11 (FIG. 3) are the same as the angles of incidence of the outer running wheel ring of the rotating blades 11 (FIG. 2). The speed of the steam emerging from the inner race is

 blades 11 (Fig. 4). The speed of the steam leaving the inner ring of the rotor blades 11 is therefore also greater here than that of the steam emerging from the outer ring of the same blades 11, because on the one hand the peripheral speed of the inner ring is lower and secondly the inner speed
 EMI1.4
 The passage of the steam through the guide vanes 14 is recorded.



   In the case of blades of this embodiment according to FIGS. 4 and Ï, the separating rings 7, 2 and 13 indicated by dotted lines in FIG. 1 are advantageously arranged, although the ring 1: J in the rotor blades can also be omitted in some cases.

 but also in embodiments. in which the steam is divided into three or more ring layers. The remaining energy of the steam emerging from the inner ring of rotor blades can also be carried out in stages in two or more successive impellers instead of as shown. can only be used in one way.
