Abstract
Description
Die Erfindung betrifft ein elektromagnetisches Einspritzventil für Brennkraftmaschinen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an electromagnetic injection valve for internal combustion engines according to the preamble of claim 1.
Derartige Einspritzventile sind bekannt. Aus der DE-OS 36 23 554 ist ein Einspritzven til entnehmbar, dessen Ventilschließkörper eine kegelförmige Schließfläche aufweist und mit einem entsprechend ausgeformten Düsenteil zusammenwirkt.Such injection valves are known. From DE-OS 36 23 554 is an injection valve til removable, the valve closing body has a conical closing surface and cooperates with an appropriately shaped nozzle part.
Obwohl Ventile mit kegelförmigen Oberflächen weite Verwendung finden und weit gehend zufriedenstellend funktionieren, stellt die Montage derartiger Ventile ein Pro blem dar, da bereits ein geringer Mittenversatz der Bauteile einen mondsichelförmigen Leckspalt verursachen.Although valves with conical surfaces are used widely and widely Properly functioning satisfactorily, the assembly of such valves represents a pro This is a problem because even a small center offset of the components has a crescent shape Cause leakage gap.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein gattungsgemäßes Ein spritzventil so zu gestalten, daß ein Leckspalt verhindert und eine Montage auch mit Mittenversatz der Bauteile möglich wird.Proceeding from this, the object of the invention is to create a generic one To design the spray valve so that a leakage gap is prevented and also to be installed Center offset of the components is possible.
Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merk male gelöst. Weiterbildende Merkmale sind im Unteranspruch genannt.This object is by the specified in the characterizing part of claim 1 times solved. Further features are mentioned in the subclaim.
Mit der Erfindung erreichte Vorteile werden in der nachfolgenden Beschreibung eines Ausführungsbeispiels genannt, das in der Zeichnung dargestellt ist.Advantages achieved with the invention are described in the following description Embodiment called, which is shown in the drawing.
Die Zeichnung zeigt ein elektromagnetisches Einspritzventil 1 für Brennkraftmaschi nen, gebildet aus einem Gehäuse 2, einem Filterteil 3, einem elektrischen Anschluß 4 und einem Düsenteil 5. Im Inneren weist das Ventil 1 alle für einen ordentlichen Be trieb notwendigen Bauteile auf, u.a., wie in dem Ausbruchschnitt ersichtlich ist, eine Spule 6, einen als Rundstab 7 ausgebildeten Eisenkern und einen durch Kraftwirkung einer Feder 8 gegen einen im Düsenteil 5 sichtbaren Ventilsitz 9 belasteten Ventil schließkörper 10.The drawing shows an electromagnetic injection valve 1 for Brennkraftmaschi NEN, formed from a housing 2 , a filter part 3 , an electrical connection 4 and a nozzle part 5th Inside, the valve 1 has all the components necessary for a proper operation, including, as can be seen in the cut-out section, a coil 6 , an iron core designed as a round rod 7 and a valve seat 9 that is visible through the force of a spring 8 against a valve seat 9 visible in the nozzle part 5 loaded valve closing body 10 .
Der Ventilschließkörper 10 ist in einem den magnetischen Rückschluß bewirkenden Ge häuseteil 11 axial geführt und weist eine Flachsitzfläche 12 auf, die mit dem Ventil sitz 9 des Düsenteils 5 zusammenwirkt, der ebenfalls von einer Flachsitzfläche 13 ge bildet wird. Wenigstens eine der beiden Flachsitzflächen 12, 13 weist zentrisch eine Ausnehmung 14, 15 auf, die kalottenförmig (wie am Ventilschließkörper 10 dargestellt ist) oder zylindrisch (wie am Düsenteil 5 dargestellt st) ausgeführt sein kann, so daß eine kreisringförmige Kontaktfläche besteht. Es versteht sich, daß nur eine der Flach sitzflächen 12, 13 derart ausgeführt zu werden braucht und daß die Ausnehmungsform beliebig gewählt werden kann, ohne den Bereich der Erfindung zu verlassen. The valve closing body 10 is axially guided in a magnetic yoke Ge housing part 11 and has a flat seat surface 12 which cooperates with the valve seat 9 of the nozzle part 5 , which is also formed by a flat seat surface 13 GE. At least one of the two flat seat surfaces 12 , 13 has a recess 14 , 15 centrally, which may be dome-shaped (as shown on the valve closing body 10 ) or cylindrical (as shown on the nozzle part 5 st), so that there is an annular contact surface. It goes without saying that only one of the flat seat surfaces 12 , 13 needs to be designed in this way and that the recess shape can be chosen as desired without leaving the scope of the invention.
Die Erfindung basiert auf der Überlegung, daß eine Teilefertigung mit hoher Genauig keit bezüglich der Einhaltung von Winkelvorgaben möglich ist, die hinsichzlich der Ein haltung der Mittigkeit nicht gegeben ist.The invention is based on the consideration that a part production with high accuracy is possible with regard to the compliance with angle specifications, which with respect to the on keeping the center is not given.
Mit der Erfindung ist eine Montage von Teilen mit Mittigkeitstoleranzen von erhebli cher Größe möglich geworden, ohne daß Leckspalte, Verschleiß oder sonstige Mängel der Funktionsfähigkeit der Einspritzventile 1 entstehen. Hierdurch ist auch eine wirtschaftliche Fertigung möglich.With the invention, an assembly of parts with centering tolerances of erhebli cher size has become possible without leakage gaps, wear or other defects in the operability of the injection valves 1 . This also enables economical production.
