Die Vorrichtung 10 umfasst ein Gehäuse 14, das im Wesentlichen aus einem rohrartig ausgebildeten Gehäuseabschnitt 16 mit kreisförmigem Querschnitt, der einen Fluidkanal 18 definiert, und zwei Gehäusedeckeln 20 besteht, die die einander gegenüberliegenden freien Enden des Gehäuseabschnittes 16 fluiddicht verschließen. Die Gehäusedeckel 20 sind jeweils mit einer Bohrung versehen, die einen Fluideinlass 22 und einen Fluidauslass 24 der Vorrichtung 10 bilden. Jeder Gehäusedeckel umfasst eine äußere Schulter 26, die an dem Ende des Gehäuseabschnittes 16 anliegt, und einen Umfangsabschnitt 28, der in dem Gehäuseabschnitt 16 aufgenommen und über einen in eine Ringnut 30 eingesetzten O-Ring 32 gegenüber dem Gehäuseabschnitt 16 abgedichtet ist. Zur Befestigung eines Gehäusedeckels an dem rohrartig ausgebildeten Gehäuseabschnitt 16 ist der Gehäusedeckel 20 umfänglich an der mit der Bezugsziffer 34 gekennzeichneten Position radial einwärts gecrimpt, bevorzugt kaltgecrimpt, wobei die Position 34 im Bereich des O-Rings 32 liegt. Entsprechend erfolgt nicht nur eine Fixierung des Gehäusedeckels 20 an dem Gehäuseabschnitt 16, sondern es wird auch die Dichtwirkung zwischen diesen Bauteilen durch die Wahl der Crimp-Position 34 verbessert.The
Die Gehäusedeckel 20 umfassen jeweils ein Innengewinde 35 zur Aufnahme eines Verbindungselementes 36 zum Anschließen der Vorrichtung an die Treibstoffleitung 12, wobei die Verbindungselemente 36 an ihren zur Vorrichtung 10 weisenden freien Enden mit einem entsprechenden Außengewinde 38 versehen sind. Ferner umfassen die Verbindungselemente 36 einen Schraubkopf 40 am gegenüberliegenden Ende, an dem ein Schraubenschlüssel während des Befestigens des Verbindungselementes 36 an der Vorrichtung 10 angreifen kann. Die Verbindungselemente sind an ihrem nach außen weisenden Ende jeweils mit einem Anschluss 42 versehen, über den ein freies Ende 44, 46 der Treibstoffleitung 12 gestülpt werden kann. Die Sicherung der freien Enden 44, 46 an den Anschlüssen 42 erfolgt bevorzugt über entsprechende Schlauchklemmen 48. Jedes Verbindungselement 36 ist mit einer Durchgangsbohrung 50 versehen, durch die Treibstoff hindurchfließen kann. Zur Abdichtung der Verbindung zwischen den Verbindungselemente 36 und der Vorrichtung 10 ist zwischen diesen Bauteilen jeweils ein O-Ring 52 vorgesehen, der vorliegend in einer dafür vorgesehenen Aussparung 54 angeordnet ist. Innerhalb des rohrartig ausgebildeten Gehäuseabschnittes 16 sind in Durchströmungsrichtung, die durch die mit dem Bezugszeichen A gekennzeichneten Pfeile angedeutet ist, zwei baugleiche Legierungskörper 56, ein anisotroper Magnet 58 und ein Federelement 60 angeordnet. Das Federelement 60 spannt dabei die Legierungskörper 56 und den Magneten 58 gegen das Gehäuse 14 vor. Die Legierungskörper 56 umfassen jeweils einen sich in Durchströmungsrichtung A erstreckenden Nabenabschnitt 62, und mehrere sich in einem Winkel α zur Durchströmungsrichtung A erstreckende Flügelabschnitte 64, die mit dem Nabenabschnitt 62 fest verbunden sind und sich radial auswärts von diesem erstrecken. Die Abmessungen der Legierungskörper 56 sind derart gewählt, dass diese gleitend im Fluidkanal 18 des rohrartig ausgebildeten Gehäuseabschnittes 16 aufgenommen sind. Dabei definieren jeweils zwei Flügelabschnitte 64 eines Legierungskörpers 56 und die Innenwandung des rohrartig ausgebildeten Gehäuseabschnittes 16 Durchgangsöffnungen 66, durch die der durch die Vorrichtung 10 geleitete Treibstoff die Legierungskörper 56 passiert.The

In die Vorrichtung 10 eingeleiteter Treibstoff passiert zunächst die Durchgangsöffnungen 66 der Legierungskörper 56, wobei aufgrund des Kontaktes zwischen dem Legierungskörper 56 und dem Treibstoff Spurenelemente der Legierungsbestandteile der Legierungskörper 56 an den Treibstoff abgegeben werden. Die Anordnung der Flügelabschnitte 64 der Legierungskörper 56 in einem Winkel α zur Durchströmungsrichtung A führt dabei zu einer Verwirbelung des Treibstoffes, wodurch die Anreicherung des Treibstoffs mit den Spurenelementen gefördert wird. Anschließend passiert der Treibstoff das Magnetfeld des anisotropen Magneten 48, so dass er mit einer vorbestimmten elektrischen Ladung versehen wird. Daraufhin tritt der Treibstoff aus der Vorrichtung 10 aus und wird direkt der Einspritzanlage der Verbrennungsmaschine zugeführt.Fuel introduced into the
