 Verbindung gebracht. Diese Ringe besitzen keine grössere radiale Ausdehnung als die Schaufeln und ragen daher weder an der   lnnen-noch an   der   Aussenkante   der Schaufeln hervor. Sie sind in gewissen achsialen Abständen zwischen der Befestigung und der freien Aussenkante der Schaufeln angeordnet. In dieser Weise kann man haltbare Schaufeltrommeln mit sehr kleiner radialer Ausdehnung herstellen und aus diesen Turbinen mit kleinem Durchmesser und dabei doch grossem Durchgangsquerschnitte zusammensetzen. Die so konstruierten Turbinen besitzen den Vorteil, dass die   Schanfeinnge geringeren zentrifugalen Beanspruchungen   ausgesetzt sind und ausserdem eine höhere Widerstandskraft besitzen. 



     Fig. l   der Zeichnung veranschaulicht den Vertikalschnitt einer einfachen Radialturbine. 



    Die Leitschaufelringe J undd'e LaufschsufelEinge 6 besitzen die tn Fig. 3 dargesteUte Konstruktion.   



   Fig. 2 stellt eine Turbine gleicher Art mit zwei Expansionsräumen dar, bei welcher wie in Fig. 1 die Leitschaufelringe 5 und die Laufschaufelringe 6 an ebenen Scheiben befestigt sind. Die feststehenden Schaufelringe 5 sind nicht unmittelbar am Turbinengehäuse, sondern an von diesem unabhängigen Platten 7 angebracht. 



   Fig. 5 zeigt im Schnitte einen Schauielring, bei dem die Schaufeln mit den   Verbindungs-   ringen nicht aus einem Stück hergestellt sind, wie in Fig. 4.

 Connected. These rings do not have a greater radial extent than the blades and therefore do not protrude either on the inner or on the outer edge of the blades. They are arranged at certain axial distances between the attachment and the free outer edge of the blades. In this way one can produce durable vane drums with a very small radial extent and assemble from these turbines with a small diameter and at the same time large passage cross-sections. The turbines constructed in this way have the advantage that the slopes are exposed to lower centrifugal loads and also have a higher resistance.



     Fig. 1 of the drawing illustrates the vertical section of a simple radial turbine.



    The guide vane rings J and the rotor blade rings 6 have the construction shown in FIG.



   FIG. 2 shows a turbine of the same type with two expansion spaces, in which, as in FIG. 1, the guide vane rings 5 and the rotor vane rings 6 are fastened to flat disks. The stationary blade rings 5 are not attached directly to the turbine housing, but rather to plates 7 that are independent of the latter.



   FIG. 5 shows in section a sighting ring in which the blades with the connecting rings are not made from one piece, as in FIG. 4.

PATENT-ANSPRUCH : Schaufelringe für radiale Dampf-oder Gasturbinen mit konzentrisch angeordneten Lcit- und Laufradkränzen, dadurch gekennzeichnet, dass die Schaufeln der Schaufelringe zwischen der Befestigung und der freien Aussenkante von in achsialen Abständen angeordneten ganzen konzentrischen Ringen zusammengehaltsn sind, die mit den einzelnen Schaufeln fest verbunden oder in einem Stück mit denselben hergestellt sind. EMI2.1 PATENT CLAIM: Blade rings for radial steam or gas turbines with concentrically arranged Lcit- and impeller rings, characterized in that the blades of the blade rings are held together between the attachment and the free outer edge of axially spaced whole concentric rings which are firmly connected to the individual blades or in are made in one piece with the same.
