  Vorrichtung zur Einstellung des Anfangsdruckes der Arbeitsflüssigkeit bei als Regler von Dampfmaschinen, insbesondere Dampfturbinen, wirkenden Schleuderpumpen. 



   Die Erfindung betrifft eine Vorrichtung, die bei einer als Regler wirkenden Schleuderpumpe den Flüssigkeitsdruck beim Eintritt in das Laufrad stets auf   Jer   gleichen Höhe erhalten soll. 



   Die Arbeitsflüssigkeit tritt bei dem auf der Zeichnung dargestellten   Ausführungs-   heispiel aus der allgemeinen Druckleitung bei a in das Reglergehäuse   A   ein und gelangt von hier durch die Bohrungen b der von der Maschine T angetriebenen Welle W in das Laufrad L. Durch die Drehung des Laufrades erhält die Flüssigkeit beim Austritt aus dem Laufrade einen bestimmten Enddruck, der von dem Anfangsdruck der Flüssigkeit und der Umlaufzahl des Laufrades abhängig ist.

   Um diesen Enddruck nur von der Umdrehungszahl des Laufrades allein abhängig zu machen, wird der Anfangsdruck der Flüssigkeit   gomäb   der Erfindung dadurch auf gleicher Höhe erhalten, dass der Eintritt in das Laufra !   von einem Überlauf B   umgeben ist, der stets bis zum Rande c mit Flüssigkeit gefüllt bleibt und das überschüssige Öl nach dem   Gehäuseinneren   und von da durch d nach dem Ablauf abfliessen lässt. Durch diese Vorrichtung ist der störende Einfluss der Veränderchkeit des Anfangsdruckes der   Arbeitsflüssigkeit   ausgeschaltet, da letzterer stets den gleichen, nur durch die Höhe des Umlaufs bedingten   Wert beibehält.

  Device for setting the initial pressure of the working fluid in centrifugal pumps acting as regulators of steam engines, in particular steam turbines.



   The invention relates to a device which, in the case of a centrifugal pump acting as a regulator, is intended to keep the liquid pressure at the same level as it enters the impeller.



   In the exemplary embodiment shown in the drawing, the working fluid enters the regulator housing A from the general pressure line at a and passes from here through the bores b of the shaft W driven by the machine T into the impeller L. As a result of the rotation of the impeller the liquid has a certain final pressure when it leaves the impeller, which is dependent on the initial pressure of the liquid and the number of revolutions of the impeller.

   In order to make this final pressure dependent only on the number of revolutions of the impeller, the initial pressure of the liquid is obtained at the same level according to the invention that the entry into the impeller! is surrounded by an overflow B, which always remains filled with liquid up to the edge c and allows the excess oil to flow off to the inside of the housing and from there through d to the drain. This device eliminates the disruptive influence of the variability in the initial pressure of the working fluid, since the latter always maintains the same value, which is determined only by the height of the circulation.
