Elektromagnetisch betätigtes EinspritzventilElectromagnetically operated fuel injector
Es sind bereits elektrisch gesteuerte Brennstoff-Einspritzvorrichtungen für Brennkraftmaschinen bekannt, bei denen elektromagnetisch betätigte Einspritzventile drehzahlabhängig ausgelöst und mittels einer elektronischen Steuervorrichtung eine bestimmte Zeitdauer lang offen gehalten werden, wobei diese Zeitdauer durch verschiedene Betriebsparameter der Maschine, wie Drehzahl, Drosselklappenstellung, Unterdruck im Saugrohr usw. beeinflusst wird.They are already electrically controlled fuel injectors known for internal combustion engines, in which electromagnetically actuated injection valves triggered depending on the speed and by means of an electronic control device open for a certain period of time are maintained, this period of time by various operating parameters of the machine, such as speed, throttle valve position, negative pressure in the intake manifold etc. is influenced.
Bei diesen Einspritzventilen wird dem Ventilgehäuse dauernd Brennstoff unter Druck zugeführt. Sobald die .Magnetwicklung erregt wird, gibt der mit einem Anker verbundene Ventilkörper den Zufluss zur Einspritzdüse frei und der Brennstoff wird z.B. in die Saugleitung der Maschine eingespritzt.With these injectors, the valve housing is constantly receiving fuel fed under pressure. As soon as the magnet winding is excited, the valve body connected to an armature free the inflow to the injection nozzle and the fuel is injected into the suction line of the machine, for example.
Bei'einem bekannten Einspritzventil ist der Anker als zylindrischer Koöben ausgebildet, der in eine zylindrische Magnetspule hineinragt und gegen den Druck einer als Schliessfeder dienenden Schraubenfeder betätigt wird, die ebenfalls innerhalb der Magnetspule angeordnet ist.In the case of a known injection valve, the armature is cylindrical Formed Koöben, which protrudes into a cylindrical magnet coil and against the pressure of a helical spring serving as a closing spring is actuated, which is also arranged within the solenoid.
Bei niedrigem Brennstoffdruck von z.B. 2 atü arbeiten solche Einspritzventile einwandfrei. Werden aber höhere Brennstoffdrücke, z.B. 20 atü angewendet, so reichen die magnetischen Kräfte zum Anheben des kleinen zylindrischen Kolbens nicht mehr aus.Such injectors work when the fuel pressure is low, e.g. 2 atm perfect. But if higher fuel pressures, e.g. 20 atm applied, the magnetic forces are sufficient to lift the small cylindrical one Piston no longer off.
Es ist auch ein Einspritzventil mit einem scheibenförmigen Anker und einem hufeisenförmigen Magnet bekannt. Die auf den Anker wirkenden magnetischen Kräfte sind in diesem Fall wesentlich grosser, wodurch höhere Drücke zulässig und dadurch kürzere Einspritzzeiten erreichbar sind. Als Schliessfeder dient in diesem Fall eine Membranfeder, die im Ventilgehäuse eingespannt ist. Diese ist jedoch sehr steif, und es hat sich gezeigt, dass die Schliesskraft stark von äusseren Faktoren, wie z.B. Wärmedehnung, beeinflusst wird, was das einwandfreie Funktionieren beeinträchtigt.It is also an injector with a disc-shaped armature and known as a horseshoe-shaped magnet. The magnetic acting on the armature In this case, forces are much greater, which means that higher pressures are permissible and thus shorter injection times can be achieved. Serves as a closing spring in this case a diaphragm spring that is clamped in the valve housing. These however, it is very stiff, and it has been shown that the clamping force is strong is influenced by external factors, such as thermal expansion, what the perfect Functioning impaired.
Die Erfindung beweckt ein Einspritzventil zu schaffen, das die Vorteile der beiden bekannten Bauarten aufweist, ohne deren Nachteile zu besitzen und das einfach und billig herzustellen ist.The invention aims to provide an injection valve that has the advantages of the two known types without having their disadvantages and which is easy and cheap to manufacture.

Gleitstück 12 abgestützt, das sich seinerseits direkt an den Magnetblechen 5 abstutzt. Die Feder 11 ist vorgespannt und bestrebt, den Anker 7, 7a mit seinem Ventilkörper 8 auf den Ventilsitz 9 zu drücken Zwischen dem Anker 7 . und den Magnetblechen 5 ist eine ringförmige Scheibe 13 aus nichtmagnetischem Material, z.B. Kunststoff, angeordnet, um den direkten Kontakt zwischen Anker und Magnet zu verhindern und dadurch die Remanenz zu verringern.Slider 12 is supported, which in turn is directly on the magnetic sheets 5 trims. The spring 11 is pretensioned and strives to the armature 7, 7a with to press his valve body 8 onto the valve seat 9 between the armature 7. and the magnetic sheets 5 is an annular disc 13 made of non-magnetic Material, e.g. plastic, arranged to allow direct contact between To prevent armature and magnet and thereby reduce the remanence.
Die Scheibe 13 könnte auch sternförmig ausgebildet sein, wie dies in Fig. 3 gestrichelt angedeutet ist.The disc 13 could also be formed in a star shape, like this in Fig. 3 is indicated by dashed lines.
An das Gehäuse 1 ist eine Brennstoffdruckleitung 14 angeschlossen, durch die unter einem Druck von etwa 20 atü stehender Brennstoff in den Gehäuseinnenraum und durch die Bohrung 15 zum Ringraum 16 gelangt, aus dem er durch die Düse 10 z.B. in die Saugleitung eines Motors eingespritzt wird, wenn jeweils der Ventilkörper 8 von seinem Sitz 9 abgehoben wird. Weitere Bohrungen 17* 18 verbinden den Innenraum des Schaftes 7a mit dem Innenraum des Gehäuses zwecks Druckausgleichs. Der Anker 7, 7a ist derart in die Gehäuseteile 1, 2 eingepasst, dass er bei Erregung der Magnetwicklung 3 jeweils um etwa 0,1 - 0,2 mn angehoben wird. Der Gehäuseteil 2 ist mittels eines Schraubringes 19 direkt gegen die Magnetbleche 5 gekl&nmt. Die notwendige Vorspannung der Feder 11 kann durch entsprechende Dimensionierung des Gleitstückes , 12 z.B. vor der Montage leicht eingestellt werden, während der Hub des Ankers durch die Abmessungen des Gehäuseteiles 2 und des Ankers 7 mit Zwischenecheib· 13 festgelegt.ist.A fuel pressure line 14 is connected to the housing 1, through which the fuel, which is under a pressure of about 20 atmospheres, enters the interior of the housing and through the bore 15 to the annular space 16, from which it is injected through the nozzle 10, e.g. into the suction line of an engine, when the valve body 8 is lifted from its seat 9. Further Bores 17 * 18 connect the interior of the shaft 7a with the interior of the housing for the purpose of pressure equalization. The armature 7, 7a is fitted into the housing parts 1, 2 in such a way that, when the magnet winding 3 is excited, it is in each case by about 0.1-0.2 mn is raised. The housing part 2 is clamped directly against the magnetic sheets 5 by means of a screw ring 19. The necessary preload of the spring 11 can be achieved by appropriate dimensioning of the slider , 12 e.g. can be adjusted slightly before assembly, while the armature is lifting is determined by the dimensions of the housing part 2 and the armature 7 with intermediate disc 13.
Die den Magnetblechen 5 benachbarte Oberseite des Ankers 7 ist zwtcfanässig leicht konisch ausgebildet, damit beim Anheben des Ankers der Brennstoff zwischen Anker und Magnetblechen leichter abströmen kann.The upper side of the armature 7, which is adjacent to the magnetic sheets 5, is designed to be slightly conical, so that when the armature is lifted the Fuel can flow more easily between the armature and the magnetic sheets.
In den Fig. 4 und 5 ist eine Ausführungsform eines Einspritzventils dargestellt, dessen Gehäuseoberteil 1 mit Magnetblechen 5 und Wicklung 3 im wesentlichen der Ausführungsform nach Fig. 1 entspricht. Der Gehäuseunterteil 2 ist in diesem Fall in den Oberteil 1 eingepresst oder eingeklebt. Zwischen den Magnetblechen 5 und dem Gehäuseunterteil 2 kann ein separater Zwischenring 21 angeordnet sein, durch dessen Dicke der Hub des Ankers geregelt wird und der gleichzeitig dem Anker als tangentiale Führung dient. 3ei dieser AusführurKjsform ist der Anker 7 zwar ebenfalls scheibenförmig, aber nicht rund ausgebildet, sondern es sind an zwei gegenüberliegenden Seiten zwei segment fÖKsige Teilstücke weggelassen, um sein Gewicht zu reduzieren.4 and 5 show an embodiment of an injection valve, the upper housing part 1 of which with magnetic sheets 5 and winding 3 essentially corresponds to the embodiment according to FIG. In this case, the lower housing part 2 is pressed or glued into the upper part 1. A separate intermediate ring 21 can be arranged between the magnetic sheets 5 and the lower housing part 2 , the thickness of which regulates the stroke of the armature and which at the same time serves as a tangential guide for the armature. In this embodiment, the armature 7 is also disc-shaped, but not round, but two segment-shaped sections are omitted on two opposite sides in order to reduce its weight.
