Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es sind bereits als Strahlrohrmundstücke dienende Düsen zum Zerstäuben von Flüssigkeiten bekannt geworden, die zur Erzielung eines vollen Streukegels so gestaltet sind, daß ein achsial gerichteter Hauptstrahl mit einem Ringstrahl, der durch Schraubenwindungen oder tangential geführte Bohrungen in Drehung versetzt wird, innerhalb der Düse zusammentrifft.There are nozzles for atomizing liquids that are already used as jet pipe mouthpieces became known, which are designed to achieve a full scattering cone, that an axially directed main ray with a ring ray, which is created by screw windings or tangentially guided bores is set in rotation, meets within the nozzle.

ίο Die vorliegende Erfindung bezweckt, bei derartigen Streudüsen den Streukegel zu vergrößern. Sie besteht darin, daß dem achsial gerichteten Flüssigkeitsstrahle durch geeignete Mittel ebenfalls eine schwache Drehbewegungίο The present invention aims at such nozzles to enlarge the scattering cone. It consists in being axially directed liquid jets by suitable means also produce a weak rotary motion

!■5 gegeben wird. Auf diese Weise wird beim Zusammentreffen der beiden Strahlen ein stärkeres Auseinanderreißen der miteinander zusammenstoßenden Flüssigkeitsteilchen bewirkt, so daß der Streuwinkel vergrößert wird.! ■ 5 is given. In this way, the When the two rays meet, the two rays are torn apart more strongly causes colliding liquid particles, so that the scattering angle is increased will.

Die Zeichnung stellt in Fig. ι und 2 zweiThe drawing represents in Fig. Ι and 2 two

Ausführungsformen einer derartigen Düse dar.Embodiments of such a nozzle.

Innerhalb der Düse d ist ein Rohrstück r Inside the nozzle d is a piece of pipe r

angeordnet, das auf seiner Außen- und Innenwand Schraubengänge c, e besitzt, durch welche die durch den achsialen Kanal A und den Ringkanal B hindurchtretende Flüssigkeit in drehende Bewegung versetzt wird. Die inneren Schraubengänge e besitzen aber eine weit stärkere Steigung als die äußeren c; demgemäß ist auch die Drehung des inneren Strahles eine schwächere als die des äußeren. Dies ist erforderlich, weil sich bei zu starker Drehung des inneren Strahles leicht ein hohler Streukegel bilden könnte.arranged, which has screw threads c, e on its outer and inner wall, through which the liquid passing through the axial channel A and the annular channel B is set in rotating motion. The inner screw threads e , however, have a much steeper pitch than the outer c; accordingly the rotation of the inner ray is also weaker than that of the outer. This is necessary because if the inner beam is rotated too much, a hollow scatter cone could easily form.

Um den Streuwinkel verändern und die Wirkung der Düse dem wechselnden Flüssigkeitsdrucke anpassen zu können, ist es zweckmäßig, den inneren Strahl regelbar zu machen. Die Regulierung kann, wie dies beispielsweise in Fig. 2 zu ersehen ist, durch einen in dem Rohr r angebrachten Hahn f erfolgen.In order to change the scattering angle and to be able to adapt the effect of the nozzle to the changing liquid pressure, it is advisable to make the inner jet controllable. The regulation can, as can be seen, for example, in FIG. 2, by means of a cock f mounted in the pipe r.
