Es bedarf   keiner bexondcren Begründung,   dass sich die   erwähnten   Vorteile   nur bei gleich-   zeitiger Benutzung jener Vorrichtungen erreichen lassen, die zur Erdung eines geordneten und möglichst   verlustlosen Strömungsvorganges   in der Turbine unter allen Umständen erforderlich sind. Dazu gehören die Beaufschlagung des Laufrades durch eine   entsprechend   aus-   gebi ! dete Leitvorrichtung   und die Abführung des Wassers durch ein Saugrohr, das im Bedarfsfalle noch einen entsprechenden Saugrohrrückgewinn ermöglichen muss.

   Ebenso muss während des Betriebes das ganze Laufrad vom strömenden Wasser erfüllt sein. 



   PATENT-ANSPRÜCHE :
1. Laufrad für Wasserturbinen   mit nügetartigen Schaufeln   nach Patent Nr. 73820. dadurch gekennzeichnet, dass mindestens längs eines Teiles der im Wesen senkrecht oder schräg zur Laufradachse   gerichteten Laufradschaufeln   die wahre Länge   (#)   der Schnittlinie einer Schaufelfläche mit einer Stromfläche wenigstens   angenähert   gleich der Hälfte der grössten innerhalb dieses Teiles vorhandenen Schaufelteilung (t) ist.

There is no need for any additional justification that the advantages mentioned can only be achieved with the simultaneous use of those devices which are required under all circumstances to ground an orderly flow process in the turbine with as little loss as possible. This includes the loading of the impeller by a corresponding output! dete guiding device and the discharge of the water through a suction pipe, which, if necessary, must still enable a corresponding suction pipe recovery.

   The entire impeller must also be filled with flowing water during operation.



   PATENT CLAIMS:
1. Impeller for water turbines with nüget-like blades according to Patent No. 73820. characterized in that at least along part of the impeller blades, which are essentially perpendicular or oblique to the impeller axis, the true length (#) of the intersection of a blade surface with a flow surface is at least approximately equal to half is the largest blade pitch (t) within this part.

2. Laufrad für Wasserturbinen nach Anspruch 1, dadurch gekennzeichnet, dass wenigstens eine der äusseren Flügelecken in der Weise abgerundet bzw. weggeschnitten ist, dass an der Abrundungsstelle die Schaufelprofillänge kleiner wird als die Hälfte der grössten Schaufelteilung (t). 2. impeller for water turbines according to claim 1, characterized in that at least one of the outer wing corners is rounded or cut away in such a way that on the Rounding point, the blade profile length becomes smaller than half of the largest blade pitch (t). 3. Laufrad für Wasserturbinen nach Anspruch 1, dadurciMEekennzeichnet, dass die Länge der Schaufelprofile in der Nähe der äusseren Schaufelenden kleiner und in der Nähe der Laufrad- nah grösser ist als die Hälfte der grössten Schaufelteilung (t). 3. Impeller for water turbines according to claim 1, dadurciMEek that the length of the blade profiles in the vicinity of the outer blade ends is smaller and in the vicinity of the impeller is greater than half of the largest blade pitch (t).
