Here, the magnet armature (14) is arranged in a gas-filled gas space (11) within the housing (1), wherein between the magnetic pole (3) and the armature (14) a membrane (19) the gas space (11) against the magnetic pole gas-tight seals.
Description
Die Erfindung betrifft ein Gaseinblasventil, wie es vorzugsweise verwendet wird, um gasförmigen Kraftstoff entweder in den Ansaugtrakt einer Brennkraftmaschine oder direkt in einen zugeordneten Brennraum einzudosieren. The invention relates to a gas injection valve, as it is preferably used to meter gaseous fuel either in the intake of an internal combustion engine or directly into an associated combustion chamber.
Stand der Technik State of the art
Gaseinblasventile für Brennkraftmaschinen sind aus dem Stand der Technik bekannt, beispielsweise aus der
Das weichmagnetische Material des Elektromagneten bzw. des Magnetpols kommt bei den bekannten Gaseinblasventilen mit dem gasförmigen Kraftstoff in Kontakt. Der gasförmige Kraftstoff beinhaltet jedoch häufig Verunreinigungen, z.B. Wasser oder flüssige Kraftstoffe, die Schwefel enthalten können, die mit der Zeit in den weichmagnetischen Werkstoff des Magnetpols angreifen und dort zu Korrosion führen können. Dies beeinträchtigt die Lebensdauer des Gaseinblasventils und kann schließlich zur Beeinträchtigung der Funktion führen. The soft magnetic material of the electromagnet or the magnetic pole comes in contact with the gaseous fuel in the known gas injection valves. The gaseous fuel, however, often contains impurities, e.g. Water or liquid fuels that may contain sulfur, which attack over time in the soft magnetic material of the magnetic pole and can lead to corrosion there. This affects the life of the Gaseinblasventils and may eventually lead to impairment of the function.
Vorteile der Erfindung Advantages of the invention
Das erfindungsgemäße Gaseinblasventil weist dem gegenüber den Vorteil auf, dass der gasförmige Kraftstoff nicht mit dem Elektromagneten und insbesondere nicht mit dem Magnetpol des Elektromagneten in Verbindung kommt. Dadurch ist der Magnetpol vor Korrosion geschützt, so dass die Lebensdauer des Gaseinblasventils erhöht wird. Hierzu weist das Gaseinblasventil ein Gehäuse auf, in dem ein Elektromagnet mit einem Magnetpol und einer Magnetspule angeordnet ist, der mit einem beweglich angeordneten Magnetanker zum Öffnen und Schließen einer Eindüsöffnung zusammenwirkt. Der Magnetanker ist in einem mit Gas befüllbaren Gasraum innerhalb des Gehäuses angeordnet, wobei zwischen dem Magnetpol und dem Magnetanker eine Membran angeordnet ist, die den Gasraum gegen den Magnetpol gasdicht abdichtet. The gas injection valve according to the invention has the advantage over that the gaseous fuel does not come into contact with the electromagnet and in particular not with the magnetic pole of the electromagnet. As a result, the magnetic pole is protected from corrosion, so that the life of the gas injection valve is increased. For this purpose, the gas injection valve to a housing in which an electromagnet is arranged with a magnetic pole and a magnetic coil, which cooperates with a movably arranged magnet armature for opening and closing a Eindüsöffnung. The magnet armature is arranged in a gas-filled gas space within the housing, wherein between the magnetic pole and the magnet armature, a membrane is arranged, which seals the gas space against the magnetic pole gas-tight.
Die Membran ist damit so angeordnet, dass bei der Bewegung des Magnetankers auf den Elektromagneten zu die Membran zwischen dem Magnetpol und dem Magnetanker eingeklemmt wird. Um die elektromagnetische Kraft auf den Magnetanker nicht oder nur unwesentlich zu reduzieren, ist die Dicke der Membran nur gering und beträgt vorzugsweise 50 bis 250 µm. Ebenso vorteilhaft ist es, wenn die Membran aus einem amagnetischen Werkstoff gefertigt ist, beispielsweise aus Edelstahl, um eine gute Festigkeit der Membran zu erreichen und magnetisches Kleben effektiv zu verhindern. The membrane is thus arranged so that during the movement of the armature to the electromagnet to the membrane between the magnetic pole and the armature is clamped. In order not to reduce the electromagnetic force on the armature or only insignificantly, the thickness of the membrane is small and is preferably 50 to 250 microns. It is equally advantageous if the membrane is made of a non-magnetic material, for example of stainless steel, in order to achieve a good strength of the membrane and to effectively prevent magnetic sticking.
In einer weiteren vorteilhaften Ausgestaltung ist die Membran an ihrem äußeren Rand gasdicht mit dem Gehäuse verbunden, in vorteilhafter Weise durch eine Schweißverbindung. Es kann auch vorgesehen sein, dass im Inneren des Gehäuses ein Absatz ausgebildet ist, an dem der Magnetpol anliegt, wobei die Membran zwischen dem Magnetpol und dem Absatz am Außenumfang gasdicht geklemmt ist. Bei der Anordnung der Membran durch Klemmen zwischen dem Magnetpol und einem Absatz des Gehäuses ergibt sich der Vorteil, dass die Membran zerstörungsfrei entfernt und neu montiert werden kann, was beispielsweise bei der Wartung des Gasventils notwendig sein kann. In a further advantageous embodiment, the membrane is gas-tight at its outer edge connected to the housing, advantageously by a welded connection. It can also be provided that in the interior of the housing, a shoulder is formed, against which the magnetic pole, wherein the membrane between the magnetic pole and the shoulder on the outer circumference is clamped gas-tight. In the arrangement of the membrane by clamping between the magnetic pole and a shoulder of the housing there is the advantage that the membrane can be removed without destruction and re-assembled, which may be necessary, for example, in the maintenance of the gas valve.
In einer weiteren vorteilhaften Ausgestaltung wird der Gasraum auf seiner dem Magnetpol gegenüberliegenden Seite durch eine Ventilplatte begrenzt, in der eine Eindüsöffnung oder mehrere Eindüsöffnungen ausgebildet sind. In vorteilhafter Weise umfasst der Magnetanker dabei einen Dichtkörper, der mit der Ventilplatte zum Öffnen und Schließen der einen Eindüsöffnung oder aller Eindüsöffnungen zusammenwirkt, so dass der Magnetanker zwischen dem Anschlag am Magnetpol unter Zwischenlage der Membran und dem Ventilsitz durch die Kraft des Elektromagneten bewegt werden kann. Dabei ist weiterhin in vorteilhafter Weise zwischen dem Magnetpol und dem Magnetanker eine Schließfeder unter Druckvorspannung angeordnet, die eine Schließkraft auf den Magnetanker ausübt und damit der Kraft des Elektromagneten im bestromten Zustand entgegenwirkt. Durch das Zusammenspiel einerseits der Schließfeder und deren mechanischen Kraft und der Kraft des Elektromagneten lässt sich der Magnetanker innerhalb des Gasraums bewegen und damit die Dosierung des gasförmigen Kraftstoffs. Hierbei ist in vorteilhafter Weise die Membran zwischen der Schließfeder und dem Magnetpol geklemmt, so dass sie sicher und ortsfest an ihrem Platz innerhalb des Gaseinblasventils fixiert ist und auch bei Bewegung des Magnetankers nicht bewegt wird. In a further advantageous embodiment, the gas space is limited on its side opposite the magnetic pole side by a valve plate in which an injection opening or several injection openings are formed. In an advantageous manner, the magnet armature comprises a sealing body which cooperates with the valve plate for opening and closing the one orifice or all Eindüsöffnungen so that the magnet armature between the stop at the magnetic pole with the interposition of the membrane and the valve seat can be moved by the force of the electromagnet , In this case, a closing spring is arranged under pressure prestress advantageously between the magnetic pole and the armature, which exerts a closing force on the armature and thus counteracts the force of the electromagnet in the energized state. Due to the interplay of the closing spring and its mechanical force and the force of the electromagnet, the magnet armature can be moved within the gas space and thus the dosage of the gaseous fuel. In this case, the membrane between the closing spring and the magnetic pole is clamped in an advantageous manner, so that it is securely and fixedly fixed in place in the gas injection valve and is not moved even when the magnet armature.
