Patentirt im Deutschen Reiche vom 8. August 1896 ab.Patented in the German Empire on August 8, 1896.

Die bisher bekannt gewordenen Verstellungen eines innerhalb des feststehenden Leitrades liegenden Schaufelkranzes (wie sie z. B. durch das amerikanische Patent Nr. 192691 bekannt geworden sind) haben den Uebelstand, dafs es nicht nur sehr schwierig und fast unmöglich ist, alle Oeffnungen des feststehenden Leitrades zu gleicher Zeit zu verschliefsen, sondern dafs auch beim mehr oder weniger plötzlichen Schliefsen dieser Leitradöffnungen Stöfse infolge plötzlichen Absperrens des Zuflufswassers entstehen. Letztere wirken häufig um so schädlicher, weil man im Interesse einer guten Turbinenanordnung bestrebt sein mufs, diesen verdrehbaren Schaufelkranz so schmal wie möglich zu construiren, so dafs seine Widerstandsfähigkeit nicht übermäfsig grofs gewählt werden kann.The previously known adjustments of one within the stationary stator lying blade ring (as it is known, for example, from the American patent No. 192691 have become) have the disadvantage that it is not only very difficult and almost impossible is to close all openings of the stationary guide wheel at the same time, but that even when these stator openings close more or less suddenly, there are bumps as a result sudden shut-off of the inflow water. The latter often have the same effect more harmful, because one must strive in the interests of a good turbine arrangement to this to construct the rotatable blade ring as narrow as possible, so that its resistance cannot be chosen excessively large.

Um beide Uebelstände zu vermeiden, werden in der nachfolgend beschriebenen und auf der Zeichnung in zwei Querschnitten veranschaulichten Anordnung elastische Leitschaufeln angewendet, welche nicht nur bei übergrofs eintretendem Druck nachgeben und den weiteren Durchtritt der Wassersäule bis zur Inruhesetzung derselben gestatten, sondern welche auch, und das ist der wesentliche Punkt, das gleichmäfsige Schliefsen aller Leitschaufelöffnungen des Leitrades sicher herbeiführen, ohne dafs in der praktischen Ausführung nicht erreichbare Genauigkeit der Anordnung nothwendig ist.In order to avoid both inconveniences, are described in the following and on the Drawing in two cross-sections illustrated arrangement of elastic guide vanes applied, which give way not only when the pressure is excessive and the further passage of the column of water until it is put to rest allow the same, but also which, and that is the essential point, that Ensure uniform closing of all guide vane openings of the guide wheel safely without that the accuracy of the arrangement, which cannot be achieved in practice, is necessary is.

In der Zeichnung ist B das Leitschaufelrad, b b sind die Leitschaufeln; an diesen Leitschaufeln sind federnde Blechzungen c angebracht, welche mittels vertiefter Schrauben an.In the drawing, B is the guide vane wheel, bb are the guide vanes; resilient sheet metal tongues c are attached to these guide vanes, which are attached to them by means of recessed screws.

der Rückseite der betreffenden Schaufel b befestigt werden und eine für die erwähnten Zwecke genügende Biegsamkeit und Federung besitzen und frei in das Innere des verdrehbaren Schaufelkranzes α hineinragen.the back of the blade in question b are attached and have sufficient flexibility and resilience for the purposes mentioned and protrude freely into the interior of the rotatable blade ring α.

Der verdrehbare Schaufelkranz α ist mit schnabelförmigen Leitstücken a' versehen, welche in ihrer Form und Anordnung gegenüber den federnden Blechzungen c so gewählt sind, dafs bei vollkommener Schliefsung des verdrehbaren Schaufelkranzes a die inneren Spitzen dieser Schaufeln a1 des Kranzes α gegen die federnden Leitbleche c des feststehenden äufseren Leitrades der Turbine stofsen (Fig. 3) und bei allen Zwischenstellungen aber, von ganz offen bis ganz geschlossen, eine correcte Wasserzuführung vom Leit- ins Laufrad erfolgt. The rotatable blade ring α is provided with beak-shaped guide pieces a 'whose shape and arrangement relative to the resilient sheet metal tongues c are chosen so that when the rotatable blade ring a is completely closed , the inner tips of these blades a 1 of the ring α against the resilient guide plates c The fixed outer stator of the turbine rushes (Fig. 3) and in all intermediate positions, from completely open to completely closed, a correct water supply takes place from the stator into the impeller.

Steht nun eine dieser Schaufeln von α nicht in vollkommen richtiger Stellung und Anordnung zu den federnden Blechschaufeln c, so wird entweder die letztere (Schaufel c) zurückgedrückt, bis die anderen Schaufelstücke b fest an die Blechschaufeln sich anschliefsen, oder es werden die anderen Schaufelstücke die betreffenden Blechschaufeln zurückdrücken, bis totaler Anschlufs und Abschlufs aller Leitschaufelkanäle stattgefunden hat. Diese dünnen Blechschaufeln gestatten ebenfalls die Ausnutzung des gröfsten freien Wasserquerschnitts.Is now one of these blades of α not completely correct position and arrangement c to the resilient sheet metal blades, either the latter (blade C) is pushed back until the other blade pieces b firmly to the sheet metal vanes anschliefsen, or it can be the other blade pieces which Push back the sheet metal blades in question until all guide vane channels have been completely connected and closed. These thin sheet metal blades also allow the largest free water cross-section to be used.

Zur Erläuterung der Zeichnung diene noch Folgendes.The following should also serve to explain the drawing.

In Fig. 1 sind in den Quadranten vier verschiedene Stellungen des verdrehbaren Zwischenkranzes α dargestellt; Fig. 2 zeigt einen Querschnitt, parallel der Achse; in Fig. 3 ist eineIn Fig. 1, four different positions of the rotatable intermediate ring α are shown in the quadrants; Fig. 2 shows a cross section, parallel to the axis; in Fig. 3 is a
