Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft den ZwischenleitkanalThe invention relates to the intermediate duct

einer von außen beaufschlagten Radialturbine, welcher durch die Mitte der Turbine geführt ist und entsprechend den jeweiligen Dampf mengen verbreitert bzw. verengt werden soll.a radial turbine acted upon from the outside and passed through the center of the turbine and should be widened or narrowed according to the respective steam volumes.

Gemäß der Erfindung wird die eine WandAccording to the invention, the one wall

des Zwischenleitkanals durch zwei Teile ο, φ gebildet, welche gegenläufig verstellbar sind.of the intermediate guide channel formed by two parts ο, φ , which are adjustable in opposite directions.

Fig. ι veranschaulicht einen Längsschnitt ίο durch die Turbine,Fig. Ι illustrates a longitudinal section ίο through the turbine,

Fig. 2 einen Längsschnitt durch die Einstellvorrichtung des in der Mitte der Turbine liegenden Zwischenleitkanals.2 shows a longitudinal section through the adjustment device in the middle of the turbine lying intermediate duct.

Der Dampf strömt durch die Düsen e und a des Gehäuses b in die Schaufeln c des Laufrades; zwischen den Schaufelkränzen c des Laufrades befinden sich die Leitschaufeln d. Die Düse e kann durch den Schieber f, welcher sich mit seinem' hinteren Ende g in der Längsnut h des Gehäuses b hin und her bewegt, durch letztere Eigenschaft verengt werden. The steam flows through the nozzles e and a of the housing b into the blades c of the impeller; between the blade rings c of the impeller are the guide vanes d. The nozzle e can be narrowed by the slide f, which moves with its' rear end g back and forth in the longitudinal groove h of the housing b , due to the latter property.

Um die Größe der Düsenöffnung äußerlichTo the size of the nozzle opening externally

erkennen zu lassen bzw. die Düsenöffnung auf einen gewissen Grad einstellen zu können, ist an dem Gehäuse ein zahnstangenartiger Ansatz k mit einer Skala angebracht, in welchen ein Stift I des Hebels i, den Schieber festhaltend, eingreift. Wie die Düse e ist der Kanal m, welcher Leitschaufeln υ enthält und den Dampf nochmals durch die Schaufeln zu dem Dampfaustritt η führt, durch die Leitkörper 0 und φ, in seinem Querschnitt der Menge des arbeitenden Dampfes entsprechend, einstellbar. Diese Bewegung der beiden Teile 0 und φ, welche entgegengesetzt gerichtet ist, geschieht durch zwei im entsprechenden Verhältnis zueinander stehende Zahnräder q und r, welche in Zahnsegmente s und t der beiden Teile 0 und φ greifen. Um der Bewegung eine Grenze zu setzen, stößt der Teil 0 bei seiner dem kleinsten Querschnitt des Leitkanals entsprechenden Lage gegen die Leitschaufel u. To be able to recognize or to be able to adjust the nozzle opening to a certain degree, a rack-like projection k with a scale is attached to the housing, in which a pin I of the lever i, holding the slide, engages. Like the nozzle e , the channel m, which contains guide vanes υ and leads the steam again through the vanes to the steam outlet η , is adjustable in its cross-section through the guide bodies 0 and φ according to the amount of working steam. This movement of the two parts 0 and φ, which is directed in opposite directions, takes place through two gear wheels q and r which are in a corresponding ratio to one another and which engage in tooth segments s and t of the two parts 0 and φ. In order to set a limit to the movement, the part 0 strikes against the guide vane u in its position corresponding to the smallest cross section of the guide channel.
