Description

BeschreibungDescription

Tropffreie Luftzerstäuberdüse mit im Bereich des Eingangs-, Ausgangs- und Zwischenbereiches vorhandenen Öffnungen und Durchgängen für flüssige und gasförmige MedienDrip-free air atomizing nozzle with openings and passages for liquid and gaseous media in the inlet, outlet and intermediate areas

Gegenwärtiger StandCurrent status

Der gegenwärtige Stand der Technik ist bereits in mehreren Offenlegungsschriften wie DE-OS 3201008 A\, DE-OS 1928573 und DE-OS 1949315 bzw. Patentschriften wie PS 3823497 und der bereits etwas älteren PS 949613 dargestellt. In den meisten Fällen handelt es sich um eine Flüssigkeitsdüse oder Mischkammerdüse, die von einer Luftdüse (auch Luftringkammer genannt) umgeben ist.The current state of the art is already presented in several published patent applications such as DE-OS 3201008 A\, DE-OS 1928573 and DE-OS 1949315 or patent applications such as PS 3823497 and the somewhat older PS 949613. In most cases, it is a liquid nozzle or mixing chamber nozzle that is surrounded by an air nozzle (also called an air ring chamber).

Problemproblem

Nach Beendigung eines Sprühvorganges läuft bei den üblichen Düsen, wenn auch tropfenweise, das zu versprühende flüssige Medium nach. Dies führt, außer einem geringen Verlust des flüssigen Mediums, zur örtlichen Verunreinigung mit dem flüssigen Medium.After the spraying process has finished, the liquid medium to be sprayed continues to flow through the usual nozzles, albeit drop by drop. This leads to a small loss of the liquid medium and to local contamination with the liquid medium.

Erfindunginvention

Dieses Problem wird mit den Maßnahmen der Ansprüche 1. bis 2. gelöst.This problem is solved by the measures of claims 1 to 2.

Vorteilhafte Wirkungen der ErfindungAdvantageous effects of the invention

Durch den Einbau eines federbelastenden Absperrteiles entgegen der Strömungsrichrung wird der Flüssigkeitsdurchgang nach jeder Beendigung des Sprühvorganges sofort geschlossen und somit das unerwünschte Nachlaufen (Nachtropfen) verhindert.By installing a spring-loaded shut-off part against the flow direction, the liquid passage is immediately closed after each spraying process has ended, thus preventing unwanted dripping.

Darstellung der ErfindungDescription of the invention

Die Erfindung ist anhand der Zeichnung näher erläutert.The invention is explained in more detail with reference to the drawing.

Wie man aus Fig. 1. ersieht, weist die Luftzerstäuberdüse eine Luftdüse (1) auf, in deren inneren Bereich eine Flüssigkeitsdüse (2) angebracht ist. Im Inneren der Flüssigkeitsdüse befindet sich das Absperrteil (3), das über eine Feder (4) mit einem entgegen der Strömungsrichtung definierten Druck vorgespannt ist und über eine Absperrdichtung (5) die Eingangsöffhung des Anschlußteiles (6) für das flüssige Medium verschließt.As can be seen from Fig. 1, the air atomizer nozzle has an air nozzle (1) in the inner area of which a liquid nozzle (2) is attached. Inside the liquid nozzle is the shut-off part (3), which is pre-tensioned by a spring (4) with a pressure defined against the flow direction and closes the inlet opening of the connection part (6) for the liquid medium via a shut-off seal (5).
