  Niederdruckdampfheizung. 
 EMI1.1 
 



   Die Düse 3 (Fig. 2) des Strahlapparates ist so gestaltet, dass bei c ein plötzlicher übergang des weiten Querschnittes auf den engsten Querschnitt stattfindet. Die plötzliche Querschnittsverengung bewirkt im Verein mit der scharfkantigen Abgrenzung der Innenkontur eine Kontraktion des durchtretenden Strahles. Diese Strahlkontraktion bietet ausserdem noch den Vorteil, dass der engste Strahlquerschnitt mit der durchströmenden Dampfmenge variiert. Es wird demzufolge bei niedrigen Drücken in der Hauptdampfleitung ein grösserer Durchgangsquerschnitt zur Verfügung stehen als bei hohen Drücken, so dass ein gewisser Ausgleich zwischen Druck und engstem Durchgangsquerschnitt geschaffen wird.

   Gleichzeitig bildet sich hiebei am Umfang des kleinsten Querschnittes eine Unterdruckzone, die der Erfindung gemäss zur Erhöhung der Saugwirkung des Strahlapparates dadurch benützt wird, dass im Düsenkörper Kanäle a und b angeordnet sind, die den Saugraum des Strahlapparates mit dem engsten Düsendurchgang verbinden. 



   PATENT-ANSPRÜCHE :
1. Niederdruckdampfheizung mit thermostatischem Regler für die Frischdampfzufuhr mit einem Strahlapparat, der den Umlauf des Heizmittels in den Heizrohren bewirkt, dadurch gekennzeichnet, dass der engste Teil der Dampfdüse unmittelbar und scharfkantig an einem Teil mit grösserem Durchmesser oder an einen grösseren Raum anschliesst, derart, dass ein   plötzlicher Übergang   vom grossen Querschnitt auf den engsten Querschnitt stattfindet.

  Low pressure steam heating.
 EMI1.1
 



   The nozzle 3 (Fig. 2) of the jet device is designed so that at c there is a sudden transition from the wide cross-section to the narrowest cross-section. The sudden narrowing of the cross-section, together with the sharp-edged delimitation of the inner contour, causes a contraction of the beam passing through. This jet contraction also offers the advantage that the narrowest jet cross-section varies with the amount of steam flowing through. Accordingly, at low pressures in the main steam line, a larger passage cross-section will be available than at high pressures, so that a certain balance is created between the pressure and the narrowest passage cross-section.

   At the same time, a vacuum zone is formed on the circumference of the smallest cross-section, which according to the invention is used to increase the suction effect of the jet device in that channels a and b are arranged in the nozzle body which connect the suction chamber of the jet device with the narrowest nozzle passage.



   PATENT CLAIMS:
1.Low-pressure steam heating with thermostatic regulator for the live steam supply with a jet device that causes the heating medium to circulate in the heating pipes, characterized in that the narrowest part of the steam nozzle connects directly and sharp-edged to a part with a larger diameter or to a larger space, such as that there is a sudden transition from the large cross-section to the narrowest cross-section.
