   Die Erfindung betrifft eine Anlassvorrichtung für Dampfstrahlpumpen (Injektoren), welche es ermöglicht, dass dieselben durch diese Vorrichtung sofort zum Ansprechen gebracht werden und im Falle ihres Aussetzens neuerlich selbsttätig anspringen. Nach der Erfindung wird Wasser durch eine Hilfspumpe, die ihren Arbeitsdampf aus dem Schlabberraum der Strahlpumpe erhält, in diese letztere hineingetrieben, hiedurch die Kondensation des Injektordampfes bewirkt und damit das sofortige Einsetzen der Injektorwirkung erzielt. Ist die Dampfstrahlpumpe in Tätigkeit getreten, so hört die Förderung der Anlassvorrichtung von selbst auf. 



   Setzt die Förderung der Dampfstrahlpumpe aus irgend einem Grunde aus, so springt die Anlassvorrichtung selbsttätig an und veranlasst das Wiederingangkommen der Dampfstrahlpumpe. 



   In der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht. 



   Vom Schlabberraum J führt eine Dampfleitung D zu einer kleinen Turbopumpe T mit eingebautem   Rückschlagventil,   die ihr Wasser aus der Saugleitung S des Injektors erhält und die das Druckwasser in die Saugkammer   K   des Injektors treibt. 



   Springt der Injektor an, so tritt im Schlabberraum J Unterdruck ein und die Förderung der Turbopumpe T hört auf, da im kein Arbeitsdampf mehr zuströmt. Das   Rückschlagventil   R verhindert das Einsaugen von Luft aus der Turbine bei normaler Tätigkeit des Injektors. 



   Setzt die Strahlpumpe plötzlich aus, so füllt sich der Schlabberraum J mit Dampf und die Turbopumpe T beginnt selbsttätig zu liefern, bis im Schlabberraum wieder Unterdruck herrscht und normales Saugen eingetreten ist. 



   Es ist daher die Gefahr eines Versagens der Strahlpumpe die denkbar geringste und es werden hiedurch die vielen, infolge Versagens der Injektoren hervorgerufenen schweren Störungen im Stabilund Lokomotivkesselbetrieb auf ein geringstes Mass eingeschränkt.

 EMI1.1
 



   The invention relates to a starting device for steam jet pumps (injectors), which enables the same to be made to respond immediately by this device and to start again automatically in the event of their failure. According to the invention, water is driven into the latter by an auxiliary pump, which receives its working steam from the slobber chamber of the jet pump, thereby causing the condensation of the injector steam and thus achieving the immediate onset of the injector effect. If the steam jet pump has started to work, the starter device will stop pumping by itself.



   If the delivery of the steam jet pump stops for any reason, the starting device starts up automatically and causes the steam jet pump to restart.



   An exemplary embodiment of the invention is illustrated in the drawing.



   A steam line D leads from the sloppy space J to a small turbo pump T with a built-in check valve, which receives its water from the suction line S of the injector and which drives the pressurized water into the suction chamber K of the injector.



   If the injector starts, then negative pressure occurs in the sloppy space J and the delivery of the turbo pump T ceases because working steam no longer flows into it. The check valve R prevents air from being sucked in from the turbine during normal operation of the injector.



   If the jet pump suddenly stops, the sloppy space J fills with steam and the turbo pump T begins to deliver automatically until there is negative pressure again in the sloppy space and normal suction has occurred.



   The risk of failure of the jet pump is therefore the least conceivable and the many serious disturbances in the stable and locomotive boiler operation caused by failure of the injectors are limited to the lowest possible level.
