Es kommt erfindungsgemäß bei der Montage zu einer gleichmäßigen Verformung des Verbindungselements, wohingegen bei angezogenen Magnetspannmuttern stets eine ovale bzw. ungleichmäßige Verformung zu beobachten war. Zur Realisierung der erfindungsgemäßen Verbindung sind Schieber verwendbar, welche in gleichmäßiger Weise bzw. in gleich großen Segmenten kreisrund auf den als Verbindungselement verwendeten Haltering drücken. Es erweist sich, daß die erfindungsgemäß vorgeschlagene Verbindung eine Reduzierung der Taktzeit bei der Herstellung von Magnetventilen ermöglicht, so daß die erfindungsgemäßen Magnetventile in besonderer Weise großserientauglich sind.With the solution according to the invention one is opposite conventional solutions simplified and less costly assembly of an injector body on one Magnetic assembly possible.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Magnetventils sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention Solenoid valves are the subject of the dependent claims.

Es ist bevorzugt, daß der Haltering zwei Bördelkanten aufweist, die mit entsprechenden Nuten und/oder Vorsprüngen der Magnetbaugruppe bzw. des Injektorkörpers zusammenwirken. Mit der Ausbildung von zwei Bördelkanten ist eine sehr beständige Verbindung zwischen Magentbaugruppe und Injektorkörper gewährleistet, die sich als robust und zuverlässig erweist.It is preferred that the retaining ring have two crimped edges has that with corresponding grooves and / or projections the magnet assembly or the injector body interact. With the formation of two flanged edges is a very constant connection between Magnetic assembly and injector body ensures that proves to be robust and reliable.

Gemäß einer bevorzugten Ausgestaltung des erfindungsgemäßen Magnetventils ist der Haltering elastischer als Magnetspannmuttern ausgebildet. Die notwendige Elastizität ergibt sich aus den konkreten Gegebenheiten, wobei als bevorzugte Werkstoffe für den Verbindungsring nichtrostende Stahllegierungen, wie z.B. die Legierungen 1.4303 oder 1.4301 zu erwähnen sind.According to a preferred embodiment of the invention Solenoid valve, the retaining ring is more elastic than Magnetic clamping nuts designed. The necessary elasticity results from the specific circumstances, whereby as preferred materials for the connecting ring stainless Steel alloys such as alloys 1.4303 or 1.4301 are to be mentioned.

Es ist ferner bevorzugt, daß der Haltering mit einer seitlichen Aussparung ausgebildet ist. Eine derartige Aussparung kann als Sollbruchstelle bzw.

Die Magnetspannmutter 14 weist eine nicht im einzelnen erkennbare Schraubstation auf, an der ein Gabelschlüssel zum Anziehen der Magnetspannmutter ansetzbar ist. Als nachteilig hierbei erweist sich, daß die Magnetspannmutter 14 sich bei einem derartigen Anziehen oval verformt. Auch kann es zu einer plastischen Verformung der Hülse 12a kommen. Ferner kann es durch die Wechselwirkung zwischen Mutter und Schlüssel zu einem Partikelabtrag kommen, wodurch die Gefahr der Verschmutzung des Magnetventils und der Montagelinien besteht.1 shows a conventional solenoid valve as a whole 11 denotes the solenoid valve 11 has one Magnet assembly 12, which is surrounded by a sleeve 12a, on. The operation of the magnet assembly is here not detailed as this is not the subject of the present invention. The magnet assembly 12 is by means of a magnetic clamping nut 14 with an injector body 13 connected. The magnetic clamping nut 14 does not have a individual recognizable screwing station on the one Open-end wrench can be used to tighten the magnetic clamping nut is. The disadvantage here is that the Magnetic clamping nut 14 itself when tightened in this way oval shaped. It can also cause plastic deformation the sleeve 12a come. Furthermore, it can by the Interaction between mother and key to one Particle removal comes, reducing the risk of pollution of the solenoid valve and the assembly lines.

Eine bevorzugte Ausführungsform des erfindungsgemäßen Magnetventils ist in den Figuren 2 und 3 dargestellt.A preferred embodiment of the invention Solenoid valve is shown in Figures 2 and 3.

Das Magnetventil ist hier insgesamt mit 21 bezeichnet. Es weist eine Magnetbaugruppe 22 und einen Injektorkörper 23 auf. Man erkennt ferner einen am Injektorkörper ausgebildeten Anschlussstutzen 28, welcher beispielsweise für den Anschluß einer Druckbohrung des Magnetventils an einen Hochdruckspeicher vorgesehen ist.The solenoid valve is designated here overall by 21. It has a magnet assembly 22 and an injector body 23 on. You can also recognize one by the injector body trained connection piece 28, which for example for the connection of a pressure hole of the solenoid valve a high pressure accumulator is provided.

Erfindungsgemäß sind die Magnetbaugruppe 22 und der Injektorkörper 23 mittels eines Halterings 24 miteinander verbunden. Der Haltering 24 weist hierbei eine erste Bördelkante 24a und eine zweite Bördelkante 24b auf. Die Bördelkante 24a wirkt mit einer unteren Nut 23a des Injektorkörpers 23 zusammen. Man erkennt, daß der Haltering 24 zur Ausbildung der Bördelkante 24a in die Nut 23a des Injektorkörpers 23 gebördelt ist.According to the magnet assembly 22 and the Injector body 23 together by means of a retaining ring 24 connected. The retaining ring 24 has a first one Flanged edge 24a and a second flanged edge 24b. The Flanged edge 24a acts with a lower groove 23a of the Injector body 23 together. It can be seen that the retaining ring 24 to form the flanged edge 24a in the groove 23a of the Injector body 23 is crimped.

Die zweite Bördelkante 24b umfasst eine Schulterauflage 22b einer Hülse 22a der Magnetbaugruppe 22. Es sei angemerkt, daß es sich bei der Hülse 22a um ein tiefgezogenes Bauteil handeln kann.The second flanged edge 24b comprises a shoulder rest 22b a sleeve 22a of the magnet assembly 22. It should be noted that the sleeve 22a is a deep-drawn component can act.

Zweckmäßigerweise erfolgt die Montage des dargestellten Magnetventils dadurch, daß zunächst der Haltering 24 auf den Injektorkörper 23 aufgelegt wird, und anschließend der Haltering in die untere Nut 23a des Injektorkörpers 23 gebördelt wird. Anschließend wird die Magnetbaugruppe 22 montiert bzw. mit dem Injektorkörper in Verbindung gebracht. Zweckmäßigerweise wird anschließend die Magnetbaugruppe 22 mit einem Niederhalter satt auf den Injektorkörper 23 gedrückt, während der zweite Bördelvorgang zur Ausbildung der zweiten Bördelkante 24b erfolgt. Als besonders vorteilhaft erweist sich, daß beim zweiten Bördelvorgang die Schulterauflage 22b elastisch deformierbar ist, wodurch die Herstellung der zweiten Bördelkante 24b vereinfacht ist. Eine plastische Deformierung der Schulterauflage 22b findet nicht statt.The assembly shown is expediently carried out Solenoid valve in that first the retaining ring 24 the injector body 23 is placed, and then the Retaining ring in the lower groove 23a of the injector body 23 is flanged. Then the magnet assembly 22 mounted or in connection with the injector body brought. Afterwards, the Magnetic assembly 22 with a hold-down on the Injector body 23 pressed while the second Flanging process to form the second flanging edge 24b he follows. It proves to be particularly advantageous that the second flanging process the shoulder pad 22b elastic is deformable, thereby producing the second Flanged edge 24b is simplified. A plastic one Deformation of the shoulder rest 22b does not take place.

Der Haltering hält somit die Magnetbaugruppe und den Injektorkörper zusammen. Die Bördelkanten 24a und 24b fassen hierbei in die Nut 23a des Injektorkörpers 23 bzw. um die Schulterauflage 22b der Hülse 22a.The retaining ring thus holds the magnet assembly and the Injector body together.
