Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei den bekannten Streudüsen mit besonders eingesetztem oder in das Gehäuse eingedrehtem Schraubengang wird die zur Zerstäubung notwendige Fliehkraft dadurch erzeugt, daß die Flüssigkeit durch die Gewindegänge hindurchgetrieben wird. Eine Regelung der Flüssigkeitsmenge während des Betriebes kann nur durch Verändernng des Druckes oder durch Verengung der Düsenöffnung erfolgen.In the known scattering nozzles with a specially inserted or screwed into the housing The centrifugal force necessary for atomization is generated by that the liquid is driven through the threads. A scheme of The amount of liquid during operation can only be changed by changing the pressure or by narrowing the nozzle opening.
ίο Beide Regelungsarten sind grundsätzlich nicht richtig, da in beiden Fällen die Geschwindigkeit der Flüssigkeit in den Gewindegängen und damit auch die zur Zerstäubung notwendige Fliehkraft verringert wird, so daß bei verminderter Menge auch die Feinheit der Zerstäubung verschlechtert wird.ίο Both types of regulation are fundamentally not correct, as in both cases the speed of the liquid in the threads and thus the centrifugal force necessary for atomization is reduced, so that if the amount is reduced, the fineness of the atomization is also worsened.
Die an zwei Ausführungsbeispielen in Fig. 1 und 2. dargestellte Erfindung bezweckt die Geschwindigkeit der drehenden Bewegung und damit die erzeugte Fliehkraft, von der wiederum der Grad der Zerstäubung abhängig ist, unabhängig zu machen von der Flüssigkeitsmenge. The two exemplary embodiments in FIG. 1 and 2. The invention illustrated aims at the speed of the rotating movement and thus the centrifugal force generated, on which the degree of atomization is dependent, is independent to make from the amount of liquid.
Zu diesem Zweck ist in einem nach hinten tiefer werdenden inneren Schraubengang des Düsenkopfes d eine Spindel a mit einer entsprechend nach hinten höher werdenden Schraubenrippe mit (Fig. 2) oder ohne Spielraum c (Fig. 1) für den eigentlichen Spindelquerschnitt geführt.For this purpose, a spindle a with a correspondingly higher screw rib with (Fig. 2) or without clearance c (Fig. 1) for the actual spindle cross-section is guided in an inner screw thread of the nozzle head d that becomes deeper towards the rear.
In der gezeichneten Stellung verbleibt dann zwischen dem Muttergewinde und dem Gewinde der Spindel ein Kanal b, durch den die Flüssigkeit hindurch muß, wobei sie in drehende Bewegung gesetzt wird, so daß sie beim Austritt aus der Düsenmündung durch die Fliehkraft zerstäubt wird. In the position shown, a channel b remains between the nut thread and the thread of the spindle, through which the liquid must pass, setting it in a rotating motion so that it is atomized by centrifugal force when it emerges from the nozzle mouth.
Durch Ein- oder Ausschrauben der Gewindespindel wird der Kanal vergrößert oder verkleinert oder auch ganz abgesperrt. Das Gewinde kann ein- oder mehrgängig sein.The channel is enlarged or reduced by screwing in or unscrewing the threaded spindle or even completely closed off. The thread can be single or multiple.
Nach Fig. 2 ist noch ein zweiter Kanal c auf dem Grunde des Spindelgewindes gebildet. Das Muttergewinde kann mit dem Düsenkörper fest verbunden, aber auch besonders in das Düsengehäuse eingesetzt sein.According to Fig. 2, a second channel c is also formed on the base of the spindle thread. The nut thread can be firmly connected to the nozzle body, but it can also be especially inserted into the nozzle housing.
