Description

Offene Düse für Einspritzbrennkraftmaschinen Gemenstand vorliegender Erfindung ist eine offene Düse für Verbrennungskxaftmaschinen, bei der auf einfache Weisse eine sehr gute Vernebelung des Brennstoffes erzielt-wird.Open nozzle for internal combustion engines according to the present situation Invention is an open nozzle for combustion engines, in which on simple White a very good atomization of the fuel is achieved.

Auf der Zeichnung ist die Erfindung beispielsweise dargestellt.The invention is shown in the drawing, for example.

In dem Düsenhalter i, der den Brennstoffzufuhrkanal5 enthält, sind zwei Düsenplättchen 2 und 3 übereinander angeordnet, die durch eine überwurfmutter ¢ befestigt sind. Das Plättchen 2 ist mit mehi1eren Bohrungen für den Durchtritt des Brennstoffes ausgeführt, die auf der einen Seite mit der Brennstoffleitung 5 und auf der anderen Seite mit einer Aussparung 6 im Plättchen 2 in Verbindung stehen. Das untere Düsonplättchen 3 enthält eine oder mehrere Austrittsrinündungen 7 für den Brennstoff, die entweder zylindrisch oder schwach kegelig ausgeführt sein können. Der in der Richtung dies Pfeiles durchtretende Brennstoff muß beim überströmen von der Aussparung 6 in die Mündung 7 einen scharfen Richtungswechsel durchmachen, der ein kräftiges Zerreißen der Brennstoffteilchen herbeiführt. Gleichzeitig stoßen die von verschiedenen Seiten konzentrisch auf die Öffnung, zuströmenden. Brennstoffäden aufeinander, wodurch die Vernehaung günstig beeinfluBt wird. Die Aussparung 6 kann so niedrig gehalten. werden, daß eine kräftige Drosselung beim Eintritt in die Mündung 7 erfolgt. Bei niedriger Höhe der Aussparung wird gleichzeitig das Eintreten von. Fremdkörpern größeren Durchmessers verhindert, so daß eine Filterwirkung erzielt wird, welche die Mündung frei hält.In the nozzle holder i, which contains the fuel supply channel5, are two nozzle plates 2 and 3 arranged one above the other, which are secured by a union nut ¢ are attached. The plate 2 has several holes for the passage of the fuel carried out on one side with the fuel line 5 and are on the other side with a recess 6 in the plate 2 in connection. The lower nozzle plate 3 contains one or more outlet runnings 7 for the fuel, which can be either cylindrical or slightly conical. The fuel passing through in the direction of this arrow must flow over from the recess 6 in the mouth 7 undergo a sharp change of direction, the causes the fuel particles to rupture vigorously. Bump at the same time those flowing concentrically towards the opening from different sides. Fuel threads one on top of the other, which has a positive effect on the sewing. The recess 6 can kept so low. be that a strong throttling when entering the mouth 7 takes place. If the height of the recess is low, the occurrence of. Foreign bodies of larger diameter prevented, so that a filter effect is achieved which keeps the mouth free.
