Description

Elektromagnetisches Ventil. Zusatz zur Anmeldung: B 55410 VIII c/21 g-Auslegeschrift 1175 793 Die vorliegende Erfindung betrifft ein elektromagnetisches Ventil, bei dem die Magnetspule und der zugehörige Eisenrückschluß vollständig in Isolierstoff eingehüllt sind, so daß an der Innenseite des Spulenkörpers eine druckfeste Führung aus Isolierstoff für den Kolbenanker vorhanden ist, nach Patentanmeldung B 554l0 VIII c/21 g (deutsche Auslegeschrift 1175 793). Wenn ein solches magnetisches Ventil in an sich rationeller Weise unter Zuhilfenahme von thermoplastischem Isolierstoff gefertigt wird, so kann der mit Rücksicht auf die Dichtigkeit notwendige hohe Spritnruck dazu führen, daß die dünnen Drähte der Wicklungen der Spule und ihre Anschlußenden beschädigt werden.Electromagnetic valve. Addition to registration: B 55410 VIII c / 21 g-Auslegeschrift 1175 793 The present invention relates to an electromagnetic Valve in which the solenoid and the associated iron back yoke are completely in Insulating material are encased so that on the inside of the bobbin a pressure-resistant Guide made of insulating material for the piston armature is available, according to patent application B 554l0 VIII c / 21 g (German interpretation 1175 793). If such a magnetic Valve in a rational manner with the aid of thermoplastic insulating material is manufactured, the high fuel pressure required with regard to the tightness can be achieved cause the thin wires of the windings of the coil and its terminal ends to be damaged.

Es hat sich deshalb als vorteilhaft erwiesen, bei der Fertigung des Magnetsystems gegen das Eindringen des unter hohem Druck stehenden Isolierstoffes in den Spulenkörper besondere Vorkehrungen zutreffen.It has therefore proven to be advantageous in the manufacture of the Magnetic system against the penetration of the insulating material under high pressure Take special precautions in the bobbin.

Die vorliegende Erfindung sucht diese Nachteile durch eine besondere Ausgestaltung des vorbeschriebenen Ventils zu vermeiden. Dies wird in einfacher Weise dadurch erreicht, daß erfindungsgemäß der Raum zwischen der Magnetspule bzw. zwischen deren Wiadungen und den Leitblechen des magnetischen Rückschlusses mit einem zusätzlichen Isolierstoff ausgefüllt ist, der unter niedrigem Druck eingebracht ist, um die Magnetspule gegen die beim Umhüllen des Systems mit Isolierstoff auftretenden hohen Drücke zu schützen. Dieser Isolimtoff kann entweder ein an sich bekanntes Gießharz oder ein bei niedrigem Druck gut fließender thermoplastischer Kunststoff sein. Das äußere Mantelblech wird dabei zweckmäßig als geschlossene Kappe ausgebildet. Es ist ferner vorteilhaft, gegen den hohen Spritzdruck auf der Innenseite des Spulenkörpers ein, geschlossenes, aus ferritischen Rohren und einem dazwischengeschalteten Rohr aus nichtmagnetischem Werkstoff bestehendes Rohrsystem anzuordnen.The present invention addresses these drawbacks through a particular one Avoid design of the valve described above. This becomes in easier Way achieved in that, according to the invention, the space between the magnetic coil or between their bulges and the baffles of the magnetic return with an additional insulating material is filled, which is introduced under low pressure is to protect the solenoid against the occurring when encasing the system with insulating material to protect high pressures. This Isolimtoff can either be a known one Cast resin or a thermoplastic material that flows well at low pressure be. The outer jacket sheet is expediently designed as a closed cap. It is also advantageous against the high injection pressure on the inside of the bobbin a closed one made of ferritic tubes and an intermediate tube to arrange pipe system consisting of non-magnetic material.

Weitere Merkmale der Erfindung sind in der nachfolgenden Beschreibung. unter Bezugnahme auf das in der beiliegenden Zeichnung dargestellte Ausführungsbeispiel näher erläutert sowie in den Ansprüchen enthalten.Further features of the invention are set out in the description below. with reference to the embodiment shown in the accompanying drawing explained in more detail and included in the claims.

Die Zeichnung stellt als Ausführungsbeispiel einen Längsschnitt durch den Erfindungsgegenstand dar. Der Ventilkörper 1 ist mit den Anschlußgewinden 2 und 3 versehen, durch die das Medium zu- und abfließt. Eine Membran 4 aus elastischem Werkstoff ist mit der Hilfssteuerbohrung 5 versehen. Es ist eine kleinere Bohrung 6 vorhanden, über die der Raum über der Membran angefüllt wird. Ein ferritischer, höhenbeweglicher Kern 7 endet in seinem unteren Ende in der Form eines Dichtungskegels.. An Stelle des letzteren kann auch eine elastische Dichtung vorhanden sein. Im gezeichneten Beispiel ist die Magnetspule 8 auf einen Spulenkörper 9 gewickelt. In ihm sind von. oben und unten ferritische Röhren 10 und 11 eingeschoben, welche zur Vermeidung von Kurzschlußverlusten an einer Stelle längs geschlitzt sein können. Den magnetischen Rückschluß an der Unterseite bildet die Eisenplatte 12, die gegebenenfalls, wie gestrichelt gezeichnet, nach einer oder nach mehreren Seiten nach außen verlängert sein kann, um eine günstige Befestigungsmöglichkeit mit Hilfe von Bohrungen 13 zu schaffen.As an exemplary embodiment, the drawing shows a longitudinal section the subject of the invention. The valve body 1 is with the connecting threads 2 and 3, through which the medium flows in and out. A membrane 4 made of elastic The material is provided with the auxiliary control bore 5. It's a smaller hole 6 available, through which the space above the membrane is filled. A ferritic, vertically movable core 7 ends in its lower end in the form of a sealing cone .. Instead of the latter, an elastic seal can also be present. Im drawn The magnetic coil 8 is wound onto a bobbin 9 as an example. In it are from. top and bottom ferritic tubes 10 and 11 inserted, which to avoid of short-circuit losses can be slotted lengthways at one point. The magnetic Conclusion on the underside forms the iron plate 12, which, if necessary, such as Drawn in dashed lines, extended outwards on one or more sides can be to a favorable attachment option with the help of holes 13 to create.

Den äußeren magnetischen Rückschluß und zugleich den an der oberen Stirnseite bildet eine ferritische Kappe 14. Die Drahtenden der Spulen sind nach oben durch Isolierbuchsen 15 herausgeführt und an Steckern 16 angelötet. Sämtliche Teile sind mit Isolierstoff durch Spritzen unter Druck, durch Gießen oder durch andere geeignete Verfahren umhüllt. In der Zeichnung ist dieser Isolierstoffbelag innen, außen, oben und unten mit den Zahlen 17 markiert und kreuzschraffiert. Eine Röhre 19 aus nicht magnetischem Werkstoff ist zwischen die ferritischen Rohrstücke 10 und 11 eingefügt, um zu verhindern, daß bei der endgültigen Umhüllung des Magnetsystems die gewickelte Spule durch den hohen Druck des Kunststoffes gefährdet wird. Die Eisenplatte 12 ist mit einer kleinen Bohrung 20 für den Übertritt des unter niedrigem Druck eingebrachtes Isolierstoffes versehen. Die Wirkungsweise des Ventils ist an Hand der Zeichnung verständlich.The external magnetic return and at the same time that of the upper one The end face forms a ferritic cap 14. The wire ends of the coils are after brought out through insulating bushes 15 at the top and soldered to plugs 16. All Parts are made with insulating material by injection molding under pressure, by casting or by other suitable methods wrapped. This insulating material is shown in the drawing marked inside, outside, above and below with the numbers 17 and cross-hatched. One Tube 19 made of non-magnetic material is between the ferritic tube pieces 10 and 11 inserted in order to prevent that in the final enclosure of the magnet system the wound coil is endangered by the high pressure of the plastic. the Iron plate 12 is with a small hole 20 for the passage of the under low Provide pressure applied insulating material. How the Valve can be understood from the drawing.
