Außerdem beeinflussen Ablagerungen im Zumeßquerschnitt in Laufe der Betriebszeit empfindlich die Durchflußmenge. aeßquerachnitt must be with very tight tolerances, which can only be complied with with great effort. In addition, deposits in the metering cross-section have a sensitive effect on the flow rate in the course of the operating time.

In addition, the aim is to ensure that the viscosity changes can practically no longer influence the amount of fuel injected.

In the end section on the nozzle side of the armature 6 is located on one side towards a nozzle plate 10 open hanging channel 12, into which two bores 14, inclined towards the end face 13 of the armature 6, open, which extend from the lateral surface 15 of the armature proceeding through the armature 6. The anchor 6 is slotted with a Leaf spring 16 suspended without friction. A flexible plastic membrane 17 rests on the leaf spring 16 j. Both parts 16 and are on the one hand attached to a clamping ring 18 on the armature 6 and on the other hand clamped between the housing part 2 and an attachment part 19.

Die Arbeite- und Wirkungswelse des Ventiles ist folgende: Der Kraftetoff gelangt Über eine Kraftstoff zuleitung <>5, ein Sieb 26, eine Bohrung 27 in der Stellbuchse 22 sowie über radiale Schlitze 28 in die ringförmigen Hohlräume 29 zwischen dem Anker 6 und dem Gehäuseteil 2. Mit einen Dichtring 32 wird verhindert, daß der Kraftstoff mit der Magnetspule in Berührung kommt. Zwei Schrägbohrungen 14 Im Anker 6 stellen ein· Verbindung von den Hohlräumen 29 zum Ringkanal 12 htr, der geschlossen ist, solange in der Magnetwicklung 5 kein Strom flleSt. ffer.n jedoch für «inen Einspritzvorgang die Magnetwicklung an Spannung gelegt und dann der Anker 6 angezogen wird, kann der Kraftstoff unter der Stirnfläche 9 deB Dichtkörpers 8 zur DUsenbohrung 11 gelangen, wobei weiterer Kraftstoff durch die Schrägbohrungen 14 nachflieUt. In Fig. 3 und 4 ist die Lage der Schrägbohrungen 14 durch den schematisch dargestellten Anker 6 besonders deutlich gezeigt. Die Bohrungen 14 verlaufen ausgehend von der Mantelfläche 15 unter einem von der Stirnfläche de3 Ankers 6 und der jeweiligen Bohrungsachse festgelegten Winkel oe = 40° zum Ringkanal 12, Denkt man sich die BohrungenThe working and action of the valve is as follows: The fuel reaches the ring-shaped cavities 29 between the armature 6 and the housing part 2 via a fuel supply line <> 5, a sieve 26, a bore 27 in the adjusting sleeve 22 and via radial slots 28 A sealing ring 32 prevents the fuel from coming into contact with the solenoid. Two inclined bores 14 in the armature 6 establish a connection from the cavities 29 to the annular channel 12, which is closed as long as there is no current in the magnet winding 5. ffer.n However, for "inen injection process placed the magnet winding tension and the armature 6 is attracted, the fuel may be the end face 9 de B sealing body 8 reach the DUsenbohrung 11, wherein further fuel nachflieUt by the oblique bores fourteenth In Fig. 3 and 4, the position of the inclined bores 14 through the armature 6 shown schematically is shown particularly clearly.

in axialer Richtung auf die Stirnfläche des Ankers 6 projiziert, so münden die von der Mantelfläche 15 ausgehenden Bohrungen 14 tangential in den Kingkanal 12 ein. Durch diese Anordnung der Bohrungen 14 wird der Kraftstoff Im Ringkanal 12 in Rotation versetzt. Die Bewegung des Kraftstoffes setzt sich dabei aus einer Komponente in Umfnngsrichtung und eiriur in Aueflußrichtung, d.h. in Achsrichtung der Düse 11 zusammen. Damit ergibt sich bei konstanter Durchflußmenge, die durch, den Zwischenraum zwischen der Dichtfläche 9 und der Düsenplatte 10, d. hc durch den Ankerhub bestimmt ist, eine umso kleinere Ausflußkomponenta, je größer die Umfangekomponente der Kraftstoffbewegung ist. Die Ausflußkomponente bestimmt also zu einem wesentlichen Teil die aus der Düse 11 austretende Menge des Kraftstoffs.projected in the axial direction onto the end face of the armature 6, so the bores 14 extending from the lateral surface 15 open tangentially into Kingkanal 12. This arrangement of the bores 14 is the fuel is set in rotation in the annular channel 12. The movement of the fuel consists of one component in the circumferential direction and eiriur in the outflow direction, i.e. in the axial direction of the nozzle 11 together. With a constant flow rate, the result is the space between the sealing surface 9 and the nozzle plate 10, d. hc is determined by the armature stroke, the smaller the outflow component, the greater the circumferential component of the fuel movement. The outflow component thus determines to a significant extent the amount of fuel emerging from the nozzle 11.
Besondere deutlich wird dieser Efi'ekt aus Fig. 2. Die Kurve A zeigt die aus der Düse 11 in der.Zelteinheit austretende Kraftstoffmenge in Abhängigkeit vom Hub H des Ankers für den Fall, daß der Kraftstoff durch radiale oder achsparallele Bohrungen wie bei den seither bekannten Elektromagnetventilen zur Dichtfläche gelangt. Im GegensatzThis effect is particularly clear from FIG. 2. Curve A shows the amount of fuel emerging from the nozzle 11 in the tent unit as a function of the stroke H of the armature in the event that the fuel is fed through radial or axially parallel bores, as in the case of the previously known Solenoid valves reaches the sealing surface. In contrast
hierzu zeigt die Kurve B die durch die Erfindung erzielte Abhängigkeit der Kraftstoffmenge, wenn der Kraftstoff in Rotation versetzt wird. Zwischen den Werten a und b ist nur eine geringe Änderung festzustellen. Die Ausflußmenge des Kraftstoffes aus der Düse 11 1st also im Bereich zwischen den Hubwerten a und b weitgehend unabhängig von Änderungen des Zumeßquerschnittes.in this regard, curve B shows the dependency achieved by the invention the amount of fuel when the fuel is rotated. There is only a slight change between the values a and b. The outflow quantity of the fuel from the nozzle 11 is thus largely independent of in the area between the stroke values a and b Changes in the metering cross-section.
Durch die erfindungsgemäfie Ausführung des Flachankers 6 ist es weiterhin möglich, die Viskos!tätsabhangigkeit der Durchflußmenge zu korrigieren. Es hat sich gezeigt, daß durch die Rotation des Kraft- ' stoffes und die daraus resultierende tangentiale Bewegungskomponente des Kraftstoffes eich ein Effekt ergibt, der die Auswirkungen der Viükoeltüteschwankungen uuf die ausfließende Kraftstoffmenge kompensiert, bzw. stark herabsetzt.The design of the flat anchor 6 according to the invention continues to do so possible to increase the viscosity dependence of the flow rate correct. It has been shown that the rotation of the force material and the resulting tangential movement component of the fuel calibrates an effect which the effects of the Fluctuations in the food bag are compensated for the amount of fuel flowing out, or greatly reduced.
Ein weiterer Vorteil ist darin zu sehen, daß der Ausbreitungswinkel den zerstäubten, aua der Düse 11 austretenden Kraftstoffes durch das Vorsatzteil 19 und durch die darin angeordnete Bohrung 20 begrenzt wird«Another advantage is that the angle of propagation the atomized fuel exiting from the nozzle 11 is limited by the attachment 19 and by the bore 20 arranged therein «

Han kann daher durch geeignete Formgebung den Ausbreitungewinkel leicht dem jeweiligen Motor anpassen. In der dargestellten Anordnung wird durch die ringförmige Blattfeder 16 und die zentrierend angreifende, aehraubenffirmige Druckfeder 21 eine reibungafreie Aufhängung des Ankers erzielt. Durch die zentral, auf den Anker 6 wirkende Druckfeder 21 wird der Anker 6 mit seiner Dichtfläche 9 genau nach der Düsenplatte 10 ausgerichtet und damit die DUse 11 im geschlossenen Zustand des Ventils sehr gut abgedichtet.Han can therefore easily adjust the angle of propagation by shaping it appropriately adapt to the respective engine. In the arrangement shown, through the annular leaf spring 16 and the centering acting, aehraubenffirmige compression spring 21 a frictionless suspension of the Ankers scored. By the compression spring acting centrally on the armature 6 21, the armature 6 with its sealing surface 9 is exactly after the nozzle plate 10 aligned and thus the nozzle 11 is very well sealed in the closed state of the valve.
Ein weiterer Vorzug des Ventile ist seine kurze Abfallzeit. Diese wurde dadurch erzielt, daß der magnetische Widerstand im Luftspalt zwischen dem Gehäuseteil 2 und dem Anker 6 wesentlich größer als der-Another advantage of the valve is its short fall time. This was achieved by the magnetic resistance in the air gap between the housing part 2 and the armature 6 is much larger than the
