Description

Umsteuerbarü Turbine mit festen Laufschaufeln sichelförmigen Querschnitts. Die Erfindung betrifft eine durch abwechselnd entgegengesetzte Schaufeln sichelförmigen Querschnitts umsteuerbare Turbine und kennzeichnet sich der Hauptsache nach dadurch, daß die einzelnen Schaufeln des Laufrades zwecks Erzielung gleichen Wirkungsgrades bei Vor- und Rückwärtsgang mit den Stirn- und Rückenflächen abwechselnd derart aneinandergesetzt sind, daß muldeii#' `° und sichelförmige iRäume stets gleicher Größe entstehen.Reversible turbine with fixed blades, sickle-shaped cross-section. The invention relates to a sickle-shaped by alternately opposing blades Cross-section reversible turbine and is mainly characterized by that the individual blades of the impeller in order to achieve the same efficiency in forward and reverse gear with the front and back surfaces alternately juxtaposed in this way are that muldeii # '`` ° and sickle-shaped i-spaces always arise of the same size.

Auf' der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise wiedergegeben. Es sind Abb. i ein schematisches Gesamtbild, das die Art und Weise der Beaufschlagung eines Rades wiedergibt, Abb. z ein Schnitt durch das Rad in einer Durchmesserebene, aus dem zu ersehen ist, wie die Einzelschaufeln des gleichen Modells, abwechselnd entgegengesetzt gestellt, zu einem Radkranz vereinigt sind, in vergrößertem Maßstabe.On 'the drawing, the invention is in one embodiment, for example reproduced. There are fig. I a schematic overall picture showing the way the loading of a wheel reproduces, Fig. z a section through the wheel in a Diameter plane from which it can be seen how the individual blades of the same model, alternately opposite, united to form a wheel rim, in enlarged Scale.

Das Turbinenrad j besteht aus einem Radkörper und einzeln zu befestigenden SchaufeIn e (Abb. z). Das Treibmittel wird dem Turbinenrade gemäß Abb. i durch die Düsen der Steuergehäuse i bzw. k zugeführt. Es sind stets nur die auf der einen Seite des Gehäuses lt befindlichen Düsen tätig, entsprechend der gewünschten Drehrichtung der Turbine. Bei voller Leistung der Turbine arbeiten sämtliche Düsen der Steuergehäuse einer Seite, während bei verminderter Leistung eine Anzahl der Düsen abgeschaltet werden kann oder nur die Düsen des Steuergehäuse* h oder diejenigen des Gehäuses i eingeschaltet werden können.The turbine wheel j consists of a wheel body and must be fastened individually Shovel e (Fig. Z). The propellant is supplied to the turbine wheel as shown in Fig. I by the Nozzles of the control housing i or k supplied. It's always only on one side Side of the housing according to the nozzles located, according to the desired direction of rotation the turbine. When the turbine is running at full power, all of the nozzles in the control housing work one side, while a number of the nozzles are switched off at reduced power or only the nozzles of the control housing * h or those of the housing i can be switched on.
