  Mit Abdampf und Flischdampf arbeitender Injektor., 
Bei den bisherigen mit Frischdampf und Abdampf arbeitenden Injektoren mit zwei einander   umschliessenden   Dampfdüsen bildet die äussere Dampfdüse die Mündung der Abdampfleitung, wogegen die innere Dampfdüse mit der Frischdampfleitung in Verbindung steht. 



   Wenn solche Injektoren höher angeordnet sind, als der Wasserspiegel des Wasserbehälters, sind sie nicht immer in Gang zu setzen, weil ein Ansaugen des Speisewassers, besonders bei grösseren Saughöhen, unmöglich ist, wenn Dampf oder Luft in die Abdampfleitung eintritt. Das meistens in die Abdampfleitung eingeschaltete Abschlussorgan ermöglicht allerdings ein Ansaugen, wenn es vollkommen dicht ist, was jedoch im Betrieb bei längerem Gebrauch nicht zu erreichen ist. 



   Die Erfindung betrifft einen mit Frischdampf und Abdampf arbeitenden Injektor, der saugend angeordnet werden kann und das Speisewasser anhebt, selbst wenn die Abdampfleitung geöffnet wird und Luft und niedergespannter Abdampf in den Injektor eintritt. Dies wird dadurch erreicht, dass die Abdampfdüse von einer   Frischdampfdüse   umschlossen wird, weil der Mantel des durch die äussere Dampfdüse strömenden Ringstrahles die erforderliche Saugwirkung ausübt. 



   Die Figur veranschaulicht eine Ausführungsform eines solchen Abdampfinjektors. 



   Es bezeichnet 1 das Gehäuse des Injektors, 2 den Wasserraum,. 3 die Abdampfleitung,   4   die Frischdampfleitung. Die Mündung der Abdampfleitung bildet die innere   Dampf düse J, welche   von der äusseren Dampfdüse 6 umschlossen ist, die die Mündung der Frischdampfleitung 4 bildet. Die innere Dampfdüse 5 ragt im Sinne der Bewegungsrichtung des Dampfes mehr in den Injektor hinein als die äussere Dampfdüse 6, wodurch eine verbesserte Saugfähigkeit des Ringstrahles erreicht wird. 



   PATENT-ANSPRÜCHE :
1. Mit Abdampf und Frischdampf arbeitender Injektor zur   Kesselspeisung   mit zwei einander   umschliessenden   Dampfdüsen, dadurch gekennzeichnet, dass die innere Dampfdüse   (5)   mit der Abdampfleitung (3), die äussere Dampfdüse   (6)   mit der Frischdampfleitung   (4)   verbunden ist.

  Injector working with exhaust steam and concentrated steam.,
In previous injectors with live steam and exhaust steam with two steam nozzles that surround one another, the outer steam nozzle forms the mouth of the exhaust steam line, while the inner steam nozzle is connected to the live steam line.



   If such injectors are arranged higher than the water level of the water tank, they are not always to be started because it is impossible to suck in the feed water, especially at higher suction heights, if steam or air enters the exhaust line. The closing element, which is usually switched into the exhaust line, allows suction when it is completely tight, which, however, cannot be achieved in operation with prolonged use.



   The invention relates to an injector which works with live steam and exhaust steam, which can be arranged with suction and which raises the feed water, even when the exhaust steam line is opened and air and low-pressure exhaust steam enter the injector. This is achieved in that the exhaust steam nozzle is enclosed by a live steam nozzle because the jacket of the ring jet flowing through the outer steam nozzle exerts the required suction effect.



   The figure illustrates an embodiment of such an exhaust steam injector.



   It denotes 1 the housing of the injector, 2 the water space. 3 the exhaust line, 4 the live steam line. The mouth of the exhaust line forms the inner steam nozzle J, which is enclosed by the outer steam nozzle 6, which forms the mouth of the live steam line 4. The inner steam nozzle 5 protrudes more into the injector in the sense of the direction of movement of the steam than the outer steam nozzle 6, as a result of which an improved suction capacity of the ring jet is achieved.



   PATENT CLAIMS:
1. Injector working with exhaust steam and live steam for feeding the boiler with two steam nozzles surrounding each other, characterized in that the inner steam nozzle (5) is connected to the exhaust line (3), the outer steam nozzle (6) to the live steam line (4).
