  Abdampf-Injektor 
 EMI1.1 
 



   In die Dampfdüse   d   reicht eine Hilfsdüse j für Frischdampf. Eine   zusätzliche Dampfdüse   erhält Abdampf aus einem Kanal m. An diese schliessen die   Vereinigimgsdüse n   und die Ausströmdüse o. 



   Die Betätigung aer   Da'npfdüsc d erfrlgt   in einem bestimmten Bereich, der die erforderliche ÖffnungfürdenDurchtrittvonWasserzwischen der Dampfdüse d und dem   nassek-onus   e gewährleistet. Wenn aber die Betätigungsspindel über diesen Bereich hinaus betätigt wird, sperrt der Ringschieber a die Wasserzufuhr ab. Beim Anlassen erfolgt die erste Bewegung des Handgriffes an der Spindel so, dass letztere die Dampfdüse d in den Arbeitsbereich bringt. Dies bewirkt auch eine Drehung des Schiebers zur Öffnung der Wasserzufuhr. Nun ist der Injektor in der Stellung für richtige Arbeitsweise und jedwede Regelung der   Wasserzuft., thr,   welche dann notwendig ist, wird in erster Linie durch Bewegung der Dampfdüse d bewirkt, welche den Ringraum c ändert, da sich der Ringschieber gleichzeitig bewegt. 



   PATENTANSPRÜCHE : 
1. Abdampf-Injektor mit einer zur Regelung der Wasserzufuhr axial verschiebbaren Dampf- düse und einem Wasserventil, das die Wasser- zufuhr absperrt, wenn die Dampfdüse durch die
Spindel aus ihrem normalen Arbeitsbereich gerückt wird, dadurch gekennzeichnet, dass das als Drehschieber ausgebildete Wasserventil (a) an einer zur Einstellung der Dampfdüse (d) verdrehbaren Spindel (f) sitzt.

  Exhaust steam injector
 EMI1.1
 



   An auxiliary nozzle j for live steam extends into the steam nozzle d. An additional steam nozzle receives exhaust steam from a duct m. The union nozzle n and the discharge nozzle o close to this.



   The actuation of the steam nozzle d requires a certain area that ensures the necessary opening for the passage of water between the steam nozzle d and the wet cone e. But if the actuating spindle is actuated beyond this range, the ring slide a blocks the water supply. When starting, the first movement of the handle on the spindle takes place in such a way that the latter brings the steam nozzle d into the work area. This also causes the slide to rotate to open the water supply. Now the injector is in the position for correct operation and any regulation of the water supply., Thr, which is then necessary, is primarily effected by moving the steam nozzle d, which changes the annular space c, since the annular slide moves at the same time.



   PATENT CLAIMS:
1. Exhaust steam injector with a steam nozzle that can be moved axially to regulate the water supply and a water valve that shuts off the water supply when the steam nozzle passes through the
The spindle is moved out of its normal working range, characterized in that the water valve (a) designed as a rotary slide sits on a spindle (f) which can be rotated to adjust the steam nozzle (d).
