Description

Düse mit vermehrter Luftzuführung. Die Wirkung der Vorrichtungen zur Sonderbewetterung, bei welchen eine Druckluft= Strahldüse in die Lutte eingebaut ist, ist wesentlich davon abhängig, daß die erzeugte Druckluftströmung möglichst parallel zur Luttenwand geführt wird und diese erst in größerer Entfernung von der Düse trifft.Nozzle with increased air supply. The effect of the devices for Special ventilation in which a compressed air = jet nozzle is built into the duct is, is essentially dependent on the fact that the compressed air flow generated as possible is guided parallel to the duct wall and this only at a greater distance from the Nozzle hits.

Die Erfindung betrifft eine Düse, welche so eingestellt werden kann, daß stets die beste Wirkung erzielt wird. An dem. die Düsenöffnung in bekannter Weise umgebenden Trichter ist als Fortsetzung ein Hohlzylinder angeordnet, dessen Länge veränderlich ist. Da durch diesen Stutzen die durch die Düse erzeugte Luftströmung eingeschnürt wird, kann man durch die Veränderung seinem Länge die Luftverteilung den jeweiligen Verhältnissen so anpassen, daß die günstigste Luftförderung in der Lutte erzielt wird.The invention relates to a nozzle which can be adjusted so that the best effect is always achieved. To the. the nozzle opening in known Way surrounding funnel is arranged as a continuation of a hollow cylinder whose Length is changeable. Because the air flow generated by the nozzle through this nozzle is constricted, you can change the air distribution by changing its length adapt to the respective conditions so that the most favorable air flow in the Lutte is achieved.

Man kann bei einer mit dieser Düse versehenen Lutte Öffnungen in der Wandung anbringen, durch welche Luft angesaugt wird, welche die Menge der geförderten Luft erhöht.With a duct provided with this nozzle, openings can be made in the Attach wall through which air is sucked in, which the amount of conveyed Air increased.

In der Zeichnung ist eine Ausführungsform der Vorrichtung dargestellt. In der Lutte f ist der Düsenkörper k angeordnet, vor dessen Diisenöffnung a mittels der Stege c in an sich bekannter Weise ein Trichter b befestigt ist. Dieser Trichter besitzt einen zylindrischen Ansatz, an welchen mittels Gewinde in der Länge verstellbar der Rohrstützen d angebracht ist. An dem Trichter schließen sich hier Rohre e an, welche durch die Luttenwand führen und zur Zuführung von Außenluft dienen. Zur Ansaugung von Außenluft enthält die Luttenwand ferner die öffnungen g.In the drawing, an embodiment of the device is shown. The nozzle body k is arranged in the duct f, in front of its nozzle opening a by means of the webs c a funnel b is attached in a known manner. This funnel has a cylindrical extension on which the length can be adjusted by means of a thread the pipe supports d is attached. Pipes e connect to the funnel, which lead through the duct wall and serve to supply outside air. For suction of outside air, the duct wall also contains the openings g.
