Abstract

The application relates to a spraying nozzle for windscreen washing installations of motor vehicles. In order to make possible, with only one nozzle with one outlet opening, action upon the entire surface of a windscreen to be wiped, it is envisaged according to the invention that two pipe sections are led up to one another with their free ends, apart from a narrow gap, bent in such a manner that the central longitudinal axes of their bent regions enclose with one another a preferably acute angle and that the two pipe sections are interconnected on a part of their circumference on their side facing away from the spraying direction.

Description

Die Erfindung betrifft eine Spritzdüse für Scheibenwasch­ anlagen von Kraftwagen.The invention relates to a spray nozzle for windshield washer systems of motor vehicles.

Der vorliegenden Erfindung lag die Aufgabe zugrunde, eine Spritzdüse für eine Scheibenwaschanlage eines Kraftwagens so auszubilden, daß mit nur einer Düse mit einer Aus­ trittsöffnung ein Beaufschlagen der gesamten zu wischenden Fläche einer Windschutzscheibe möglich ist.The present invention was based on the object Spray nozzle for a windscreen washer system of a motor vehicle to train so that with only one nozzle with one off the entire opening to be wiped Surface of a windshield is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwei Rohrabschnitte mit ihren freien Enden bis auf einen schmalen Spalt derart abgebogen aneinander herangeführt sind, daß die Mittellängsachsen ihrer abgebogenen Bereiche einen vorzugsweise spitzen Winkel miteinander einschließen, und daß die beiden Rohrabschnitte auf ihrer der Spritz­ richtung abgewandten Seite auf einem Teil ihres Umfangs miteinander verbunden sind.This object is achieved in that two pipe sections with their free ends except for one narrow gap bent so brought together are that the central longitudinal axes of their bent areas enclose a preferably acute angle with one another, and that the two pipe sections on their the spray side facing away on part of its circumference are interconnected.

In herstellungsmäßig vorteilhafter Ausgestaltung der Er­ findung ist weiter vorgesehen, daß die Rohrabschnitte von zwei Rohren gebildet werden und die Verbindung durch Löten, Kleben od. dgl. erfolgt.In a manufacturing advantageous embodiment of the Er invention is further provided that the pipe sections of two pipes are formed and the connection through Soldering, gluing or the like.

Der Gegenstand der Erfindung soll im folgenden anhand von zwei in der Zeichnung dargestellten Ausführungsbei­ spielen näher erläutert werden.The subject matter of the invention will be described in the following of two exemplary embodiments shown in the drawing play will be explained in more detail.

In der Zeichnung zeigen:The drawing shows:

Fig. 1 einen Schnitt durch eine Spritzdüse mit zwei getrennten Waschflüssigkeitszuleitungen, Fig. 1 shows a section through a spray nozzle with two separate washing liquid feed lines,

Fig. 2 einen Schnitt nach der Linie II-II in Fig. 1, und Fig. 2 shows a section along the line II-II in Fig. 1, and

Fig. 3 einen Schnitt entsprechend Fig. 1 durch eine Spritzdüse mit nur einer Waschflüssigkeits­ zuleitung. Fig. 3 shows a section corresponding to Fig. 1 through a spray nozzle with only one washing liquid supply.

Die in den Fig. 1 und 2 der Zeichnung dargestellte Spritzdüse wird von zwei Rohrabschnitten 1 a, 1 b gebildet, die an ihren freien Enden bis auf einen schmalen Spalt 2 derart abgebogen aneinander herangeführt sind, daß die Mittellängsachsen ihrer abgebogenen Bereiche einen spitzen Winkel α miteinander einschließen. An ihrer der Spritz­ richtung abgewandten Seite sind die beiden Rohrabschnitte 1 a, 1 b dem Spalt 2 gegenüberliegend auf einem Teil ihres Umfangs durch eine Löt- oder Schweißnaht 3 miteinander verbunden. Die Länge dieser Naht 3 bestimmt die Größe des in Fig. 2 dargestellten Flüssigkeitsaustritts­ winkels β. Die hier dargestellte Spritzdüse kann an zwei getrennte, nicht dargestellte Waschflüssigkeits­ leitungen angeschlossen werden. The spray nozzle shown in FIGS. 1 and 2 of the drawing is formed by two pipe sections 1 a , 1 b , which are bent towards one another at their free ends except for a narrow gap 2 such that the central longitudinal axes of their bent regions form an acute angle α include with each other. On their side facing away from the spray direction, the two pipe sections 1 a , 1 b opposite the gap 2 are connected to one another on part of their circumference by a soldered or welded seam 3 . The length of this seam 3 determines the size of the liquid exit angle β shown in FIG. 2. The spray nozzle shown here can be connected to two separate washer fluid lines, not shown.

Die abgewandelte Ausführungsform der erfindungsgemäßen Spritzdüse nach Fig. 3 der Zeichnung wird von zwei Rohrabschnitten 4 a, 4 b gebildet, die an ihren dem Spalt 2 gegenüberliegenden Enden so zusammengeführt sind, daß sie an eine gemeinsame Waschflüssigkeitszu­ leitung 5 angeschlossen werden können.The modified embodiment of the spray nozzle according to FIG. 3 of the drawing is formed by two pipe sections 4 a , 4 b , which are brought together at their ends opposite the gap 2 so that they can be connected to a common washing liquid supply line 5 .

Je nach Erstreckung der Naht 3 kann bei beiden Ausführungs­ formen der Flüssigkeitsaustrittswinkel bis annähernd 180° betragen.Depending on the extent of the seam 3 , the liquid exit angle can be up to approximately 180 ° in both embodiments.

Es hat sich gezeigt, daß durch das Zusammentreffen der beiden Flüssigkeitsströme im Spaltbereich eine besonders günstige fächerartige Ausbreitung der Waschflüssigkeit erfolgt.It has been shown that the meeting of the two liquid flows in the gap area one particularly favorable fan-like spread of the washing liquid he follows.

Im Gegensatz zu den in der Zeichnung dargestellten und vorstehend beschriebenen Ausführungsformen der Erfindung wäre es auch denkbar, ein Rohrstück zu biegen und den Spalt durch einen Einschnitt herzustellen.In contrast to those shown in the drawing and Embodiments of the invention described above it would also be conceivable to bend a pipe section and the Create a gap by making an incision.
