Stand der TechnikState of the art
Die Offenlegungsschrift
Aus der Offenlegungsschrift
Die zwischen dem Magnetkern und dem Anker angeordnete Restluftspaltscheibe bewirkt eine Dämpfung des Ankeranschlags und wirkt somit unerwünschten Prellvorgängen des Ankers entgegen. In Abhängigkeit von der konkreten Ausgestaltung der Restluftspaltscheibe kann diese zwischen dem Innenpol oder dem Außenpol des Magnetkerns und dem Anker angeordnet sein. Der Abstand zwischen Magnetkern und Anker abzüglich der Dicke der Restluftspaltscheibe gibt den maximalen Ankerhub an.The arranged between the magnetic core and the armature residual air gap plate causes an attenuation of the armature stop and thus counteracts unwanted bouncing of the armature. Depending on the specific configuration of the residual air gap disc, it may be arranged between the inner pole or the outer pole of the magnetic core and the armature. The distance between the magnetic core and the armature minus the thickness of the residual air gap disc indicates the maximum armature stroke.
Bei Einsatz einer solchen Magnetbaugruppe in einem Magnetventil zur Betätigung eines Kraftstoffinjektors kann der Kontakt der Anschlagflächen mit dem Kraftstoff dazu führen, dass sich Beläge ausbilden, welche den Ankerhub verändern und auf diese Weise zu einem abweichenden Öffnungs- und Schließverhalten des Kraftstoffinjektors führen. In der Regel ist die Belagbildung durch die Alterung bzw. die verminderte Oxidationsstabilität des Kraftstoffs bedingt. Zink- oder Natriumanteile im Kraftstoff können beispielsweise zur Ausbildung von Alterungspolymeren und Metallseifen führen, die sich an den Oberflächen ablagern. Durch die zunehmende Beimischung von Biokraftstoff zum Dieselkraftstoff kann es zudem vermehrt zu Ablagerungen kommen. Insbesondere können Additive, wie beispielsweise Detergenzien, die eigentlich der Stabilisierung der Biokraftstoffe dienen, eine Belagbildung fördern. Ferner trägt eine erhöhte Temperatur zur Belagbildung bei.When using such a magnet assembly in a solenoid valve for actuating a fuel injector, the contact of the stop surfaces with the fuel can lead to the formation of deposits, which change the armature stroke and thus lead to a different opening and closing behavior of the fuel injector. In general, the formation of deposits is conditioned by the aging or the reduced oxidation stability of the fuel. Zinc or sodium in the fuel, for example, can lead to the formation of aging polymers and metal soaps, which deposit on the surfaces. The increasing addition of biofuel to diesel fuel can also lead to increased deposits. In particular, additives, such as detergents, which actually serve to stabilize the biofuels, can promote deposit formation. Furthermore, an increased temperature contributes to the formation of deposits.
Ausgehend von dem vorstehend genannten Stand der Technik soll eine Magnetbaugruppe für ein Magnetventil angegeben werden, bei welcher die vorstehend genannten Probleme nicht oder zumindest in deutlich vermindertem Maße auftreten.Based on the above-mentioned prior art, a magnet assembly for a solenoid valve is to be specified, in which the aforementioned problems do not occur or at least to a significantly reduced extent.
Zur Lösung der Aufgabe wird eine Magnetbaugruppe mit den Merkmalen des Anspruchs 1 vorgeschlagen. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Die Aufgabe wird ferner gelöst durch ein Magnetventil mit den Merkmalen des Anspruchs 7. Darüber hinaus wird ein Verfahren zur Herstellung einer Restluftspaltscheibe für eine erfindungsgemäße Magnetbaugruppe vorgeschlagen.To solve the problem, a magnet assembly with the features of claim 1 is proposed. Advantageous developments of the invention are specified in the subclaims. The object is further achieved by a solenoid valve having the features of claim 7. In addition, a method for producing a residual air gap disc for a magnet assembly according to the invention is proposed.
Offenbarung der ErfindungDisclosure of the invention
Die für ein Magnetventil zur Betätigung von Kraftstoffinjektoren vorgeschlagene Magnetbaugruppe umfasst eine Magnetspule sowie einen Innenpol und einen Außenpol aufweisenden Magnetkern. Ferner umfasst die Magnetbaugruppe einen mit der Magnetspule zusammenwirkenden hubbeweglichen Anker sowie eine zwischen dem Anker und dem Magnetkern angeordnete Restluftspaltscheibe zur Ausbildung eines Hubanschlags. Erfindungsgemäß ist die Restluftspaltscheibe aus belagabweisendem Kunststoff hergestellt oder enthält einen solchen. Der belagabweisende Kunststoff trägt dazu bei, dass es an den Oberflächen der Restluftspaltscheibe, insbesondere an den Anschlag- bzw. Kontaktflächen der Restluftspaltscheibe mit dem Anker und/oder dem Magnetkern, nicht oder zumindest in deutlich vermindertem Maße zur Ausbildung unerwünschter Beläge kommt, durch welche der Ankerhub beeinflusst bzw. verändert werden könnte. Vorzugsweise bestehen daher zumindest die Anschlag- bzw. Kontaktflächen der Restluftspaltscheibe mit dem Anker und/oder dem Magnetkern aus belagabweisendem Kunststoff. In einem Magnetventil zur Betätigung eines Kraftstoffinjektors unterstützt die erfindungsgemäße Magnetbaugruppe ein gleich bleibendes Öffnungsund Schließverhalten des Kraftstoffinjektors.The proposed for a solenoid valve for actuating fuel injectors magnetic assembly comprises a magnetic coil and an inner pole and an outer pole having magnetic core. Further, the magnet assembly comprises a cooperating with the solenoid liftable armature and arranged between the armature and the magnetic core residual air gap disc to form a stroke stop. According to the invention, the residual air gap disk is made of covering-repellent plastic or contains such. The covering-repellent plastic contributes to the fact that on the surfaces of the residual air gap disc, in particular at the stop or contact surfaces of the residual air gap disc with the armature and / or the magnetic core, does not or at least to a significantly reduced extent to form undesirable deposits through which the Anchor stroke could be influenced or changed. Preferably, therefore, there are at least the stop or contact surfaces of the residual air gap disc with the armature and / or the magnetic core of lining-repellent plastic. In a solenoid valve for actuating a fuel injector, the magnetic assembly according to the invention supports a consistent opening and closing behavior of the fuel injector.
Vorzugsweise ist oder enthält der belagabweisende Kunststoff ein Silikon oder ein polyflouriertes Kohlenwasserstoffpolymer, insbesondere Polytetrafluorethylen (PTFE). Derartige Kunststoffe weisen eine sehr niedrige Oberflächenspannung auf, so dass sie belagabweisend wirken. PTFE ist darüber hinaus sehr reaktionsträge, so dass hieraus ausgebildete Oberflächen zudem vor aggressiven Substanzen geschützt sind.Preferably, the scale-repellent plastic is or contains a silicone or a polyfluorinated hydrocarbon polymer, in particular polytetrafluoroethylene (PTFE). Such plastics have a very low surface tension, so that they have a coating repellent effect. In addition, PTFE is very inert, so that surfaces formed therefrom are also protected against aggressive substances.
Gemäß einer bevorzugten Ausführungsform der Erfindung enthält der belagabweisende Kunststoff nanoskalige Zuschläge. Die nanoskaligen Zuschläge führen zu einer Rauhigkeit der Oberflächen, welche ebenfalls einer Belagbildung entgegen wirkt. According to a preferred embodiment of the invention, the coating-repellent plastic nanoscale aggregates. The nanoscale additives lead to a roughness of the surfaces, which also counteracts a deposit formation.
Die Dicke der Restluftspaltscheibe wird den Erfordernissen des jeweiligen Werkstoffs angepasst. Vorzugsweise besitzt die Restluftspaltscheibe eine Dicke von weniger als 80 µm, weiterhin vorzugsweise von weniger als 50 µm.The thickness of the residual air gap disc is adapted to the requirements of the respective material. Preferably, the residual air gap disc has a thickness of less than 80 microns, more preferably less than 50 microns.
Gemäß einer Weiterbildung der Erfindung wird vorgeschlagen, dass in den Werkstoff der Restluftspaltscheibe eine Armierung, insbesondere ein Metallgitter, eingebettet ist. Durch die Armierung wird die Robustheit der Restluftspaltscheibe erhöht. Insbesondere wirkt die Armierung einer unerwünschten Verformung der Restluftspaltscheibe entgegen, welche ebenfalls den Ankerhub beeinflussen bzw. verändern könnte. Eine solche Armierung wirkt sich insbesondere bei sehr dünnen Restluftspaltscheiben als vorteilhaft aus.According to one embodiment of the invention, it is proposed that a reinforcement, in particular a metal grid, be embedded in the material of the residual air gap disk. The reinforcement increases the robustness of the residual air gap disc. In particular, the reinforcement counteracts an undesired deformation of the residual air gap disk, which likewise could influence or change the armature stroke. Such a reinforcement has an advantageous effect, in particular with very thin residual air gap disks.
Des Weiteren wird ein Verfahren zur Herstellung einer Restluftspaltscheibe einer erfindungsgemäßen Magnetbaugruppe vorgeschlagen. Bei diesem Verfahren wird ein Metallgitter mit einem belagabweisenden Kunststoff umspritzt und der Kunststoff anschließend ausgehärtet. Auf diese Weise lassen sich sehr dünne und zugleich robuste, insbesondere formsteife, Restluftspaltscheiben herstellen.Furthermore, a method for producing a residual air gap disk of a magnet assembly according to the invention is proposed. In this method, a metal mesh is coated with a coating-repellent plastic and then cured the plastic. In this way it is possible to produce very thin and at the same time robust, in particular dimensionally stable, residual air gap disks.
Zur Lösung der eingangs genannten Aufgabe wird ferner ein Magnetventil zur Betätigung von Kraftstoffinjektoren mit einer erfindungsgemäßen Magnetbaugruppe vorgeschlagen. Die erfindungsgemäße Magnetbaugruppe trägt zu einem gleich bleibendem Öffnungs- und Schließverhalten des Kraftstoffinjektors bei.To solve the object mentioned above, a solenoid valve for actuating fuel injectors with a magnetic assembly according to the invention is also proposed. The magnet assembly according to the invention contributes to a consistent opening and closing behavior of the fuel injector.
