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.
