Abstract
Description
Die Erfindung betrifft einen Kraftstoffinjektor zum Einspritzen von in einem Kraftstoffspeicher unter hohem Druck vorgehaltenem Kraftstoff in den Brennraum einer Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The The invention relates to a fuel injector for injecting in a fuel storage under high pressure reserve fuel in the combustion chamber of an internal combustion engine according to the preamble of Claim 1.
Zum Einspritzen von Kraftstoff, der in einem Kraftstoffspeicher unter hohem Druck vorgehalten ist, in den Brennraum einer Brennkraftmaschine (Common-Rail-Einspritzsystem) sind Kraftstoffinjektoren bekannt. Solche Kraftstoffinjektoren haben typischerweise zwei hydraulische Flüssigkeitswege. Ein Hauptkanal führt vom Injektoreingang zur Einspritzdüse, ein zweiter Kanal zweigt an geeigneter Stelle vom Hauptkanal ab und führt zu einem Servoventil, mit dem der Steuerdruck des Steuerraums im Sinne eines Öffnens und Schließens der Düsennadel geschaltet wird.To the Injecting fuel into a fuel tank under high pressure is kept in the combustion chamber of an internal combustion engine (Common rail injection system) fuel injectors are known. Such fuel injectors typically have two hydraulic ones Liquid paths. A main channel leads from the injector inlet to the injection nozzle, a second channel branches at a suitable point from the main channel and leads to a servo valve, with the control pressure of the control room in the sense of opening and closing the nozzle needle is switched.
Naturgemäß sind im Kraftstoff immer Partikel bis zu einer bestimmten Größe enthalten. Deshalb sind in vielen bekannten Injektoren eingangsseitig Filter oder andere Konstruktionselemente vorgesehen, die Partikel oberhalb einer für den Injektor schädlichen Größe zurückhalten.By nature are in the Fuel always contain particles up to a certain size. Therefore, in many known injectors on the input side filters or other construction elements provided, the particles above one for damaging the injector Withhold size.
Die zur Steuerung der Injektoren vorgesehenen Steuerventile sollen das zugeführte elektrische Steuersignal so schnell wie möglich in eine Änderung des Steuerdrucks umsetzen, je schneller das Ansprechverhalten der Ventile, desto besser.The intended to control the injectors control valves to the supplied electrical control signal as soon as possible in a change of Control pressure, the faster the response of the valves, the better.
Eine Steigerung der Schaltgeschwindigkeit wird unter anderem erreicht durch eine Verkleinerung des Hubes des Ventilstellgliedes, was natürlich bedeutet, dass Partikel, die größer sind als der Hub, durch den Ventilspalt nicht hindurchtreten können und sich in dem Ventilspalt einklemmen und dadurch die Funktion des Ventils stören.A Increasing the switching speed is achieved among other things by reducing the stroke of the valve actuator, which of course means that particles that are bigger as the stroke, can not pass through the valve gap and pinching in the valve gap and thereby the function of the Valve disturb.
Wenn die oben genannten eingangsseitigen Filter in Bezug auf die zulässige Partikelgröße weiter verfeinert werden, steigt zunehmend der Durchflusswiderstand mit entsprechend zunehmender Beeinträchtigung der hydraulischen Eigenschaften des Injektors.If the above-mentioned input filter further refined with respect to the allowable particle size be increasingly, the flow resistance increases accordingly increasing impairment the hydraulic properties of the injector.

Die Aufgabe der Erfindung ist es einen verbesserten Kraftstoffinjektor der vorausgesetzten Art zu schaffen. Insbesondere soll ein Kraftstoffinjektor geschaffen werden, wel cher gegen in dem zugeführten Kraftstoff enthaltene Fremdkörperpartikel weitestgehend unempfindlich ist.The The object of the invention is an improved fuel injector of the presupposed kind. In particular, a fuel injector is to be created are wel cher against contained in the fuel supplied Debris particles is largely insensitive.
Die Aufgabe wird durch einen Kraftstoffinjektor mit den Merkmalen des Anspruchs 1 gelöst.The Task is performed by a fuel injector with the characteristics of Claim 1 solved.
Vorteilhafte Weiterbildungen und Ausführungsformen des erfindungsgemäßen Kraftstoffinjektors sind in den Unteransprüchen angegeben.advantageous Further developments and embodiments the fuel injector according to the invention are in the subclaims specified.
Durch die Erfindung wird ein Kraftstoffinjektor für Brennkraftmaschinen, der in einem Düsenkörper eine axiale, vom Kraftstoff durchströmte Bohrung aufweist, geschaffen. Die Bohrung nimmt eine im Düsenkörper axial verschieblich geführte Düsennadel auf, die an ihrem einen Ende eine Sitzfläche im Düsenkörper besitzt, und die an ihrem anderen Ende eine auf dem Umfang der Düsennadel aufsitzende, relativ zur Düsennadel verschiebliche Buchse trägt. Die Buchse grenzt, federnd an der Düsennadel abgestützt, in Anlage gegen ein axial an den Düsenkörper anschließendes Bauteil des Kraftstoffinjektors einen Steuerraum ab, der über einen Zulaufkanal in der Buchse mit dem kraftstoffumströmten Raum auf der Außenseite der Buchse in Verbindung steht, und der einen von einem Steuerventil gesteuerten Ablaufkanal aufweist. Erfindungsgemäß ist an der Buchse ein Filter zur Filterung des über den Zulaufkanal zum Steuerraum strömenden Kraftstoffs vorgesehen.By The invention will be a fuel injector for internal combustion engines, the in a nozzle body one axial, flowed through by the fuel Bore has created. The bore takes a in the nozzle body axially slidably guided Nozzle needle on, which has at its one end a seat in the nozzle body, and at their another end one sitting on the circumference of the nozzle needle, relative to the nozzle needle slidable socket carries.
