Description

Flüssigkeitsgesteuertes Einspritzventil für Verbrennungsmaschinen. Gegenstand des Patents 451 413 bildet ein flüssigkeitsgesteuertes Einspritzventil für Verbrennungsmaschinen, welches dadurch gekennzeichnet ist, daß die Einspritznadel zwischen einem mit dem Ventilgehäuse einen ringförmigen Austrittsspalt bildenden Zapfen an sich bekannter Art und einer ebenfalls an sich bekannten Angriffsfläche für den Brennstoffdruck eine Abstufung besitzt in der Weise, daß mit der Wandung des Ventilgehäuses eine Drosselstelle mit Wirbelkante und eine weitere Angriffsfläche für den Brennstoffdruck entsteht, welche beim Anheben der Nadel im Anschluß an die an sich bekannte Steuerfläche zur Wirkung kommt und damit die Steuerbewegung der Nadel regeln hilft.Liquid-controlled injection valve for internal combustion engines. The subject of patent 451 413 is a fluid controlled injection valve for internal combustion engines, which is characterized in that the injection needle between one with the valve housing forming an annular outlet gap Pin of a type known per se and an attack surface that is also known per se for the fuel pressure has a gradation in such a way that with the wall of the valve housing a throttle point with eddy edge and a further attack surface for the fuel pressure, which occurs when the needle is raised following the known control surface comes into effect and thus the control movement of the Adjusting the needle helps.

Gegenstand des. vorliegenden Zusatzpatentes bildet ein flüssigkeitsgesteuertes Einspritzventil, welches dadurch gekennzeichnet ist, daß der in die Düsenmündung eingreifende Zapfen selbst wieder abgestuft ist und die Abstufung in die Mündungsebene der Düse verlegt ist.The subject of the present additional patent is a fluid-controlled one Injection valve, which is characterized in that the nozzle opening engaging pin itself is again graded and the gradation into the mouth plane the nozzle is misplaced.

Dadurch wird die Auflösung der Brennstoffäden in Nebel- und Dampfschwaden noch mehr begünstigt, und je nach der Größe und Gestalt, insbesondere dem Durchmesser des Zapfens und der Stärke der Abstufung, kann der kegelförmige Brennstoffschleier in seiner Ausdehnung verändert, d. h. die Form des in den Verbrennungsraum eintretenden Brennstoffschwadens der Form des Verbrennungsraumes selbst angepaßt werden. Auch können die Randpartien von Verbrennungsräumen, welche teilweise oder ganz in den Kolben verlegt sind, mit Brennstoffnebel beschickt und zündreife Gemische in ihnen erzielt werden.This causes the fuel threads to dissolve into clouds of mist and steam even more favored, and depending on the size and shape, especially the diameter of the tenon and the strength of the gradation, the conical fuel veil can be changed in extent, d. H. the shape of the one entering the combustion chamber Fuel plume to be adapted to the shape of the combustion chamber itself. Even the edge parts of combustion chambers, which are partially or completely in the Pistons are misplaced, charged with fuel mist and ready-to-ignite mixtures in them be achieved.

Auf der Zeichnung ist ein Ausführungsbeispiel eines Einspritzventils nach der Erfindung im Längsschnitt veranschaulicht.The drawing shows an embodiment of an injection valve illustrated according to the invention in longitudinal section.

Die Einspritznadel i besitzt zwischen einen mit dem Ventilgehäuse 4 einen ringförmigen Austrittsspalt 3 bildenden Zapfen 26 und der Angriffsfläche io für den Brennstoffdruck die Abstufung 25. Der Zapfen 26 ist nun nach der Erfindung selbst wieder abgestuft, und die Abstufung ist in die Mündungsebene der Düse verlegt, so daß in dem Austrittsspalt 3 oder in seiner Nähe auch auf der Innenseite eine Wirbelkante 25a gebildet wird.The injection needle i has between a to the valve housing 4 comprises an annular outlet gap 3-forming pin 26 and the engagement surface io for the fuel pressure, the gradation 25. The pin 26 is now graded according to the invention itself again, and the gradation is moved to the mouth plane of the nozzle so that a vortex edge 25a is formed in the exit gap 3 or in its vicinity also on the inside.

Mit 8 ist die Brennstoffzuführung bezeichnet.The fuel supply is denoted by 8.
