Das in den Fig. 1 und 2 dargestellte erfindungsgemäße Ventil 1 weist einen Ventilkörper 2 mit einer Ventil kammer 3 und einem Ventilsitz 4 auf. In den oberen Teil des Ventilkörpers 2 ist über ein Gewinde 5 ein Gehäuse 6 eines elektromagnetischen Betätigers 7 eingeschraubt, in dem eine Elektrospule 8, ein Magnetkern 9 und ein Anker 10 vorgesehen sind. Der Anker 10 kann bevorzugt als im Querschnitt flachrechteckförmige, kreisrunde Scheibe ausgebildet sein, deren Außendurchmesser so bemessen ist, daß sie für eine leichtgängige axiale Verlagerung in Richtung gegen den Magnetkern 9 oder den Ventilsitz 4 weitgehend spielfrei in dem unteren Teil des Gehäuses 6 geführt ist. An der dem Ventilsitz 4 zugewandten unteren Seite des scheibenförmigen Ankers 10 kann eine Gewindehülse 11 angeordnet sein, die ein Sackloch 12 besitzt.The valve 1 according to the invention shown in FIGS . 1 and 2 has a valve body 2 with a valve chamber 3 and a valve seat 4 . In the upper part of the valve body 2 , a housing 6 of an electromagnetic actuator 7 is screwed via a thread 5 , in which an electric coil 8 , a magnetic core 9 and an armature 10 are provided. The armature 10 can preferably be designed as a circular disk with a flat rectangular cross section, the outer diameter of which is dimensioned such that it is guided largely without play in the lower part of the housing 6 for a smooth axial displacement in the direction against the magnetic core 9 or the valve seat 4 . On the lower side of the disk-shaped armature 10 facing the valve seat 4 , a threaded sleeve 11 can be arranged which has a blind hole 12 .
In einer Ebene unter dem Anker 10 befindet sich in einem kleinen Abstand zu letzterem eine Dichtplatte 13, die über eine Schraubverbindung 14 mit dem Anker 10 verbunden ist. Dafür kann die Dichtplatte 10 einen nach oben vorstehenden Gewindezapfen 15 aufweisen, der in das Sackloch 12 der Gewindhülse 11 des Ankers 10 einschraubbar ist.A sealing plate 13 , which is connected to the armature 10 via a screw connection 14, is located at a small distance from the armature 10 in a plane. For this purpose, the sealing plate 10 can have an upwardly projecting threaded pin 15 which can be screwed into the blind hole 12 of the threaded sleeve 11 of the armature 10 .
Die Dichtplatte 10 kann vorzugsweise etwa in Form einer dünnen Membran als kompakte Funktionsbaueinheit ausge bildet sein und weist eine Flachformfeder 16 und einen Elastomermantel 17 auf. Die Flachformfeder 16 ist als dünne Scheibe ausgeführt und besitzt schmale Federstege 18, die durch Aussparungen getrennt und in ein und der selben Ebene z. B. in Form einer Spirale angeordnet sein können. Der Gewindezapfen 15 kann zweckmäßig direkt an der Flachformfeder 16 z. B. durch Nieten, Schweißen, Kleben oder dergleichen befestigt sein.The sealing plate 10 can preferably be formed approximately in the form of a thin membrane as a compact functional unit and has a flat spring 16 and an elastomer jacket 17 . The flat spring 16 is designed as a thin disc and has narrow spring bars 18 , which are separated by recesses and in one and the same plane z. B. can be arranged in the form of a spiral. The threaded pin 15 can conveniently directly on the flat spring 16 z. B. by rivets, welding, gluing or the like.
Der Elastomermantel 17 kann z. B. aus einem Nitrilkaut schuk, EPDM oder Silikonkautschuk hergestellt sein und umschließt die Flachformfeder 16 an der oberen und an der unteren Seite und füllt auch die Aussparungen zwischen den Federstegen 18 aus, so daß die Flachform feder 16 fest in dem Elastomermantel 17 integriert bzw. eingebettet ist und somit ein baueinheitlich kompaktes Funktionselement mit sehr standfesten und zuverlässigen Federungseingenschaften und dauerhafter Dichtfunktion zur Abgrenzung der Ventilkammer 3 gegenüber den Funk tionsteilen des Betätigers 7 gegeben ist.The elastomer jacket 17 can, for. B. be made of a nitrile rubber, EPDM or silicone rubber and encloses the flat spring 16 on the upper and lower sides and also fills the recesses between the spring bars 18 , so that the flat spring 16 is firmly integrated in the elastomer jacket 17 or is embedded and thus a structurally compact functional element with very stable and reliable suspension properties and permanent sealing function to delimit the valve chamber 3 from the radio function parts of the actuator 7 is given.
Der äußere Umfang des Elastomermantels 17 kann zweck mäßig als dichtschnurartiger Wulst 19 ausgebildet sein, der die Dichtplatte 13 quer zu ihrer Ebene beidseitig etwas überragt. Ein schmaler Umfangsrand 20 der Flach formfeder 16 überragt in deren Ebene den Wulst 19. Die Fig. 1 zeigt, daß der Wulst 19 und der Umfangsrand 20 zwischen einer treppenstufenförmig ausgebildeten Schulter 21 des Ventilkörpers 2 und einer stirnseitig abgestuften Dichtfläche 22 des Gehäuses 6 durch ent sprechendes Anziehen des Gewindes 5 fest eingespannt sein können, so daß die Dichtplatte 13 am Umfang unverrückbar gelagert ist und zugleich eine Abdichtung der Ventilkammer 3 und der zwischen dem Ventilkörper 2 und dem Gehäuse 6 bestehenden Gehäuseteilung 23 gegeben ist.The outer circumference of the elastomer sheath 17 can be expediently designed as a sealing cord-like bead 19 which slightly protrudes beyond the sealing plate 13 on both sides transversely to its plane. A narrow peripheral edge 20 of the flat form spring 16 extends beyond the bead 19 in its plane. Fig. 1 shows that the bead 19 and the peripheral edge 20 between a step-shaped shoulder 21 of the valve body 2 and an end-to-end sealing surface 22 of the housing 6 can be firmly clamped by ent tightening the thread 5 , so that the sealing plate 13 on Scope is immovably supported and at the same time a seal of the valve chamber 3 and the existing housing division 23 between the valve body 2 and the housing 6 is given.
Im mittleren Bereich der Dichtplatte 13 kann der Elastomermantel 17 einen an der Unterseite vorstehenden Dichtteil 24 aufweisen, der gegen den Ventilsitz 4 andrückbar ist und eine hohe Dichtfunktion gewährleistet. Wenn das Ventil 1 für den Durchfluß des Mediums geöffnet werden soll, wird der Anker 10 bei mit Spannung versorg ter Elektrospule 8 nach oben gegen den Magnetkern 9 gezogen. Dabei wird der Dichtteil 24 der Dichtplatte 13 ungefähr entsprechend dem Hub des Ankers 10 von dem Ventilsitz 4 abgehoben, so daß das Medium frei hindurch strömen kann.In the central region of the sealing plate 13 , the elastomer jacket 17 can have a sealing part 24 which projects on the underside and which can be pressed against the valve seat 4 and ensures a high sealing function. When the valve 1 is to be opened for the flow of the medium, the armature 10 is pulled up against the magnetic core 9 when the electrical coil 8 is supplied with voltage. The sealing part 24 of the sealing plate 13 is lifted from the valve seat 4 approximately in accordance with the stroke of the armature 10 , so that the medium can flow freely through it.
Der Anker 25 und die Dichtplatte 26 der Fig. 3 sind im wesentlichen ähnlich dem zuvor beschriebenen Aus führungsbeispiel der Fig. 1 und 2 ausgeführt, jedoch mit dem Unterschied, daß beim Ausführungsbeispiel der Fig. 3 an der Unterseite des Ankers 25 ein Gewindezapfen 27 und an der Dichtplatte 26 eine noch oben ragende Gewindehülse 28 angeordnet ist, in deren Sackloch 29 der Gewindezapfen 27 einschraubbar ist.The armature 25 and the sealing plate 26 of FIG. 3 are substantially similar to the off above-described operation example of FIGS. 1 and 2 carried out, but with the difference that in the embodiment of FIG. 3 on the underside of the armature 25, a threaded stem 27 and on the sealing plate 26 there is a still protruding threaded sleeve 28 , into the blind hole 29 of which the threaded pin 27 can be screwed.
