Abstract

The valve has high and low pressure connections (2,3), a valve body magnetic armature (4) operating between the connections and a magnetic coil (5). Both connections consist of a magnetizable material and protrude into the magnetic coil to form magnetic poles connected via a short circuit plate (8) externally enclosing the coil. A magnetic iron-free volume (9) between the poles contains the magnetic armature.

Description

Die Erfindung betrifft ein elektrisches Druckschaltventil, insbesondere ein Brennstoffdruck­ schaltventil für Brennkraftmaschinen, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an electrical pressure switching valve, in particular a fuel pressure switching valve for internal combustion engines, according to the preamble of claim 1.

Es sind bereits elektrische Druckschaltventile bekannt (D 197 41 297 A1), die für Brennstoff­ versorgungssysteme von Brennkraftmaschinen zum Einsatz kommen, z. B. soll eine Brenn­ stoffspeicherkammer über ein parallel mit einer Brennstoffpumpe bestromtes Elektroventil gegenüber einer Brennstoffleitung zu- und umgekehrt abschaltbar sein.Electric pressure switching valves are already known (D 197 41 297 A1), which are used for fuel supply systems of internal combustion engines are used, for. B. is said to be a focal material storage chamber via an electric valve that is powered by a fuel pump in parallel be switched on and off in relation to a fuel line.

Hierbei liegt mit dem Elektroventil eine Ausführung vor, die im harten Alltagsbetrieb, z. B. in einem Kraftfahrzeug, bestehen muß. Es sind also hohe Anforderungen hinsichtlich Funktion und Haltbarkeit gestellt, wobei dieses Elektroventil als Massenprodukt kostengünstig her­ stellbar sein muß. Diese Anforderungen an ein gattungsgemäßes elektrisches Druckschalt­ ventil werden nicht immer erfüllt.Here, there is a version with the solenoid valve that is used in tough everyday operations, e.g. B. in a motor vehicle must exist. So there are high demands regarding function and durability, this solenoid valve being inexpensive as a mass product must be adjustable. These requirements for a generic electrical pressure switch valve are not always met.

Es ist daher Aufgabe der Erfindung, ein gattungsgemäßes Druckschaltventil derart zu ge­ stalten, daß Funktion, Haltbarkeit und kostengünstige Herstellung erreichbar sind.It is therefore an object of the invention to ge a generic pressure switching valve stalten that function, durability and inexpensive manufacture can be achieved.

Diese Aufgabe ist durch die im Kennzeichen des Anspruches 1 genannten Merkmale gelöst, vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.This object is achieved by the features mentioned in the characterizing part of claim 1, advantageous further developments are specified in the subclaims.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in the drawing and is below described.

Die Zeichnung zeigt ein elektrisches Druckschaltventil 1 im Längsschnitt, wie es insbesonde­ re als Brennstoffdruckschaltventil für Brennkraftmaschinen zum Einsatz kommen soll. Es ist mit einem Hochdruck- und einem Niederdruckanschlußstutzen 2 und 3, mit einem zwischen beiden Anschlüssen 2, 3 operierenden Ventilkörper-Magnetanker 4 und einer Magnetspule 5 ausgestattet. The drawing shows an electrical pressure switching valve 1 in longitudinal section, as it is to be used in particular as a fuel pressure switching valve for internal combustion engines. It is equipped with a high-pressure and a low-pressure connection piece 2 and 3 , with a valve body magnet armature 4 which operates between the two connections 2 , 3 and a magnet coil 5 .

Es ist nun vorgesehen, daß die beiden Anschlußstutzen 2 und 3 aus einem magnetisierba­ ren Werkstoff bestehen und mit ihren den Anschlußstutzen 2, 3 entgegengesetzten Enden in die Magnetspule 5 hineinragen und Magnetpole 6, 7 bilden, die über ein die Magnetspule 5 außen umrahmendes Rückschlußblech 8 verbunden sind, wobei zwischen den Magnetpolen 6, 7 ein magneteisenfreier Zwischenraum 9 besteht, in dem der Ventilkörper-Magnetanker 4 angeordnet ist.It is now provided that the two connecting pieces 2 and 3 consist of a magnetisierba ren material and with their connecting pieces 2 , 3 opposite ends protrude into the magnet coil 5 and form magnetic poles 6 , 7 , which via a magnetic coil 5 framing the back plate 8th are connected, between the magnetic poles 6 , 7 there is a magnet-free space 9 in which the valve body magnet armature 4 is arranged.

Es ist ersichtlich, daß eines der Magnetpole 6, 7 einen eingepreßten, nichtmagnetischen Ventilsitzeinsatz 10 aufweist, wobei eines der Magnetpole 6, 7 einen in den Ventilkörper- Magnetanker 4 hineinragenden Zapfenansatz 11 aufweist, der einen Anschlag 12 für einen aus nichtmagnetisierbarem Werkstoff bestehenden Ventilkörpereinsatz 13 bildet.It can be seen that one of the magnetic poles 6 , 7 has a pressed-in, non-magnetic valve seat insert 10 , one of the magnetic poles 6 , 7 having a pin extension 11 projecting into the valve body magnet armature 4 , which has a stop 12 for a valve body insert 13 made of non-magnetizable material forms.

Durch diese Maßnahmen ist ein Kleben des Ventilkörper-Magnetankers 4 verhindert, wobei vorteilhafterweise der Ventilkörpereinsatz 13 aus einem gegenüber einer zylindrischen Ma­ gnetanker-Aufnahmeöffnung 14 Durchlaßöffnungen 15 bildenden Profilstück 16 besteht, das einen Ventilkörper-Gummieinsatz 17 aufweist. Der Gummieinsatz 17 sichert eine sehr wirk­ same Ventildichtheit.These measures prevent the valve body magnet armature 4 from sticking, the valve body insert 13 advantageously consisting of a profile piece 16 which forms a passage opening 15 relative to a cylindrical magnet armature receiving opening 14 and which has a valve body rubber insert 17 . The rubber insert 17 ensures a very effective valve tightness.

Die weiteren Maßnahmen, daß die beiden Magnetpole 6, 7 innerhalb einer sie aufnehmen­ den Spulenkörperausnehmung 18 durch O-Ringe 19 abgedichtet sind, dienen der Funkti­ onssicherheit und Dauerhaltbarkeit des Ventils 1.The further measures that the two magnetic poles 6 , 7 are sealed within a they take up the bobbin recess 18 by O-rings 19 , the func onssicherheit and durability of the valve 1st

Es ist vorgesehen, daß die Anschlußstutzen 2, 3 gegenüber den Magnetpolen 6, 7 unter ei­ nem vorgegebenen Winkel 20 abgebogen sind, womit eine verbesserte Einbaubarkeit, z. B. in ein Kraftfahrzeug, erreicht ist. Damit die vorgegebenen Abbiegungen der Anschlußstutzen 2, 3 auch bei extremer Belastung Bestand haben, ist es erforderlich, daß aus der Spulenkör­ perausnehmung 18 herausragende Abschnitte der Anschlußstutzen 2, 3 als Vielkantab­ schnitte 21 ausgebildet sind, die durch Umspritzung mit einem Abschlußgehäuse 22 als Ver­ drehsicherung wirken, und daß an den Enden der Spulenkörperausnehmung 18 angeord­ nete Abschnitte 23 der Anschlußstutzen 2, 3 mit umlaufende Verkrallrippen 24 ausgeführt sind, die in die Wandung des Spulenkörpers 25 als Axialsicherung einrasten.It is provided that the connecting pieces 2 , 3 are bent relative to the magnetic poles 6 , 7 at a predetermined angle 20 , so that an improved installation, z. B. in a motor vehicle. So that the given bends of the connecting piece 2 , 3 even with extreme loads, it is necessary that 18 outstanding portions of the connecting piece 2 , 3 are formed as Vielkantab sections 21 from the Spulenkör perausschluß, the rotation by overmolding with a closure housing 22 as Ver act, and that at the ends of the bobbin recess 18 angeord designated sections 23 of the connecting pieces 2 , 3 are designed with circumferential claw ribs 24 which snap into the wall of the bobbin 25 as an axial securing device.

Vorteilhaft ist es, wenn das Abschlußgehäuse 22 einen umspritzten Steckeranschluß 26 und einen umspritzten Blechhalter 27 umfaßt, womit eine sichere elektrische Verbindung und sehr belastbare Halterung des Druckschaltventils gegeben ist. It is advantageous if the closure housing 22 includes an over-molded male terminal 26 and a molded sheet metal holder 27, by which a secure electrical connection and very reliable holder is given the pressure switch valve.

Alternativ hierzu kann es vorteilhaft sein, wenn das Abschlußgehäuse 22 einen Schacht 28 aufweist, in den ein Blechhalter 27 eingepreßt und durch Verbiegen von Sicherungsarmen gesichert ist.As an alternative to this, it can be advantageous if the end housing 22 has a shaft 28 into which a sheet metal holder 27 is pressed and secured by bending securing arms.
