Es sind bereits Elektromagnetventile des in Grundstellung geschlossenen Typs bekannt geworden, wozu beispielhaft auf die DE 199 36 711 A1 verwiesen wird. Darin sind Elektromagnetventile der eingangs genannten Art beschrieben, die außen am Ventilsitz-Aufnahmekörper lediglich einen Ringfilter aufnehmen, so daß Verunreinigungen der Flüssigkeit beim Abheben des Ventilschließgliedes von seinem Ventilsitz in den Innenraum des Elektromagnetventils eindringen können. There are already solenoid valves in the basic position closed type become known, for example on DE 199 36 711 A1 is referred to. Are in it Solenoid valves of the type mentioned that only a ring filter on the outside of the valve seat holder body record so that contamination of the liquid when Lifting the valve closing member from its valve seat in the Can penetrate the interior of the solenoid valve.

It is therefore the object of the invention, a Electromagnetic valve of the closed embodiment to improve that in compliance with a relatively simple, miniaturized construction a contamination of the solenoid valve is avoided.

Erfindungsgemäß wird die gestellte Aufgabe für ein Elektromagnetventil der eingangs genannten Art durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. According to the task for a Solenoid valve of the type mentioned by characterizing features of claim 1 solved.

Durch die in den Unteransprüchen aufgezeigten Maßnahmen sind zweckmäßige Ausbildungen der Erfindung angegeben, die im Zusammenhang mit den weiteren Merkmalen und Vorteilen der Erfindung nachfolgend anhand eines Ausführungsbeispieles anhand einer Zeichnung gemäß Fig. 1 näher dargestellt und erläutert werden. The measures set out in the subclaims provide expedient embodiments of the invention which, in connection with the further features and advantages of the invention, are illustrated and explained in more detail below using an exemplary embodiment and a drawing according to FIG. 1.

Das Elektromagnetventil nach Fig. 1 besteht aus einem als Kaltfließpreßteil gefertigten Magnetanker 13, einen aus einem Kaltfließpreßteil gefertigten Magnetkern 25 und einen topfförmigen Ventilaufnahmekörper 7, der am Ventilgehäuse 3 befestigt ist. Soweit dünnwandige Hülsenteile zur Anwendung gelangen, werden sie zweckmäßigerweise als Tiefziehteile oder ggf. auch als Rundknetteile ausgeführt. Im einzelnen zeigt hierzu die Fig. 1 ein hülsenförmiges, als Tiefziehteil ausgebildetes Ventilgehäuse 3, dessen beide Endabschnitte Führungsflächen 3a, 3b bilden, die auf der einen Seite von dem Magnetkern 25 und auf der anderen Seite von dem topfförmigen Ventilaufnahmekörper 7 begrenzt werden. Beide am hülsenförmigen Ventilgehäuse 3 angebrachten Teile 25, 7 sind vorzugsweise mittels einer Schweißverbindung 19 dauerhaft sowie flüssigkeitsdicht befestigt. Innerhalb dieser vorbeschriebenen Teile 25, 7 befindet sich der Magnetanker 13, der an seiner Wandung entweder mit Druckausgleichsnuten oder abbildungsgemäß mit einem Kantprofil versehen ist, um einen ungehinderten hydraulischen Druckausgleich im Ventil zu gewährleisten. Der Magnetanker 13 als auch der Magnetkern 25sind als Kaltfließpreßteile ausgeführt, wozu sich insbesondere ein Werkstoff mit der Kennzeichnung X8Cr17 oder alternativ dazu ein Werkstoff gemäß der Kennzeichnung X6Cr17 eignet. Das hülsenförmige Ventilgehäuse 3 besteht vorzugsweise aus austenitischem Stahl gemäß der Klassifikation 1.43.03. Gleicher Werkstoff gelangt zur Anwendung für den topfförmigen Ventilaufnahmekörper 7. Der Magnetkern 25 ist in Form eines Stopfens in den offenen Bereich des hülsenförmigen Ventilgehäuses 3 eingepreßt und nach den erforderlichen Einstellmaßnahmen mittels einer Schweißnaht 19 dauerhaft fixiert. Durch entsprechende Vorsprünge 11 zwischen dem Magnetkern 25 und dem Magnetanker 13, die sich entweder am einen oder am anderen vorgenannten Teil 13, 25 befinden, wird das sog. Magnetankerkleben verhindert. Zur platzsparenden Aufnahme und Führung der Rückstellfeder 8 ist entsprechend der Abbildung der Magnetanker 13 mit einer Längsbohrung versehen. Alle beschriebenen Teile befinden sich zueinander in einer koaxialen Anordnung. The solenoid valve according to Fig. 1 consists of a produced as Kaltfließpreßteil magnetic armature 13, a magnetic core made of a Kaltfließpreßteil 25 and a cup-shaped valve accommodating body 7, which is secured to the valve housing 3. As far as thin-walled sleeve parts are used, they are expediently designed as deep-drawn parts or, if appropriate, also as round kneaded parts. In particular, this Figure 1 shows the FIG. A sleeve-shaped, formed as a deep-drawn part valve body 3 whose both end portions of the guide surfaces 3 a, b form 3 bounded on one side of the magnetic core 25 and on the other side of the cup-shaped valve accommodating body 7. Both parts 25 , 7 attached to the sleeve-shaped valve housing 3 are preferably permanently and liquid-tightly secured by means of a welded connection 19 . Within these previously described parts 25 , 7 is the magnet armature 13 , which is provided on its wall either with pressure compensation grooves or, as shown, with an edge profile, in order to ensure unimpeded hydraulic pressure compensation in the valve. The magnet armature 13 and the magnet core 25 are designed as cold extrusion parts, for which purpose a material with the identification X8Cr17 or alternatively a material according to the identification X6Cr17 is suitable. The sleeve-shaped valve housing 3 is preferably made of austenitic steel according to the classification 1.43.03 . The same material is used for the cup-shaped valve receiving body 7 . The magnetic core 25 is pressed in the form of a plug in the open area of the sleeve-shaped valve housing 3 and, after the necessary adjustment measures, is permanently fixed by means of a weld seam 19 . The so-called magnetic armature bonding is prevented by corresponding projections 11 between the magnetic core 25 and the magnetic armature 13 , which are located either on one or on the other aforementioned part 13 , 25 . To save space and guide the return spring 8 , the magnet armature 13 is provided with a longitudinal bore, as shown in the illustration. All parts described are in a coaxial arrangement.

Das Elektromagnetventil ist unmittelbar am Rand 20 des topfförmigen Ventilaufnahmekörpers 7 mittels einer Außenverstemmung im Ventilträger 6 befestigt. Der Topf des Ventilaufnahmekörpers 7 weist zumindest eine radial als auch axial zur Ventillängsachse verlaufende Öffnung 26 auf, wobei die in der Ventillängsachse angeordnete Öffnung 26 gleichzeitig als Ventilsitzöffnung 1 ausgebildet ist, die mittels eines Prägeverfahrens den eigentlichen Kegeldichtsitz für das Ventilschließglied 9 bildet, während die quer dazu den Ventilaufnahmekörper 7 durchdringende Öffnung 26 in der Regel als Blendenbohrung ausgeführt ist, um in der offenen Ventilschaltstellung eine Druckmittelverbindung zwischen den unterhalb und oberhalb des Ventilschließgliedes 9 gelegenen Auslaß- und Einlaßkanälen 2, 14 im Ventilträger 6 herzustellen. Als Ventilschließglied 9 wird vorzugsweise eine im Magnetanker 13 verstemmt befestigte Kugel verwendet, die unter Wirkung einer zwischen dem Magnetanker 13 und dem Magnetkern 25 befindliche Rückstellfeder 8 in der elektromagnetisch nicht erregten Ventilstellung auf die Ventilsitzfläche des Ventilschließkörpers 9 gepreßt ist. The electromagnetic valve is attached directly to the edge 20 of the cup-shaped valve receiving body 7 by means of an external caulking in the valve carrier 6 . The pot of the valve accommodating body 7 has at least one radially and axially extending transversely to the valve longitudinal axis opening 26, with the disposed in the valve longitudinal opening 26 is formed at the same time as the valve seat opening 1, which forms the actual conical sealing seat for the valve closing member 9 by means of a stamping process, while the transverse for this purpose, the opening 26 penetrating the valve receiving body 7 is generally designed as an aperture hole in order to produce a pressure medium connection between the outlet and inlet channels 2 , 14 in the valve carrier 6 located below and above the valve closing element 9 in the open valve switching position. As the valve closing member 9 , a ball caulked in the magnet armature 13 is preferably used, which is pressed under the action of a return spring 8 located between the magnet armature 13 and the magnet core 25 in the electromagnetically non-energized valve position on the valve seat surface of the valve closing body 9 .

Die innere Abdichtung des topfförmigen Ventilaufnahmekörpers 7 in einer Stufenbohrung des Ventilträgers 6 geschieht mittels eines Dichtrings 15, der zwischen dem gestuften Ventilaufnahmekörper 7 und einer den Ventilaufnahmekörper 7 zugewandten Bohrungsstufe des Ventilträgers 6 eingespannt ist. Das Elektromagnetventil ist nach außen hin lediglich über eine einfache Außenverstemmung im Ventilträger 6 abgedichtet und befestigt, während die durch den Dichtring 15 vorgegebene untere Abdichtung des Ventilaufnahmekörpers 7 im Ventilträger 6 einen Kurzschlußstrom zwischen dem unterhalb des Ventilschließgliedes 9 in den Ventilträger 6 einmündenden Auslaßkanal 2 und dem auf Höhe des Ringfilters 23 gelegenen Querkanals (Einlaßkanal 14) verhindert. The inner seal of the cup-shaped valve accommodating body 7 in a stepped bore of the valve carrier 6 is done by means of a sealing ring 15 between the stepped valve-receiving member 7 and a valve holding body 7 facing bore step of the valve support is clamped. 6 The solenoid valve is sealed to the outside only through a simple Außenverstemmung in the valve support 6 and secured while the predetermined by the sealing ring 15 lower sealing of the valve accommodating body 7 in the valve carrier 6 a short circuit current between the opening out below the valve closure member 9 in the valve carrier 6 outlet duct 2 and the at the level of the ring filter 23 located transverse channel (inlet channel 14 ) prevented.

Ein im Durchmesser verkleinerter Hülsenabschnitt des gestuften Ventilaufnahmekörpers 7 ist abschnittsweise in einen gestuften Filtertopf 10 derart eingefügt, daß zwischen der dem Filtertopf 10 zugewandten Stufe 12 am Ventilaufnahmekörper 7 und dem Gehäuserand 21 des Filtertopfs 28 ein Axialabstand verbleibt, in dem der Dichtring 15 elastisch verspannt ruht. Dies führt zu einer besonders einfachen und dennoch funktionsgerechten sicheren hydraulischen Abdichtung zwischen dem Filtertopf 10 und dem Ventilaufnahmekörper 7, so daß über den in gewissenen Grenzen frei wählbaren Axialabstand sowohl die Fügetiefe des Filtertopfs 10 im Ventilaufnahmekörper 7 und damit auch die Einbaumaße des Filtertopfes 28 und des Ventilaufnahmekörpers 7 in der gestuften Aufnahmebohrung 18 großzügig toleriert werden können. Der gestufte Filtertopf 10 stützt sich vorteilhaft über seine außen liegende Schulter 22 an einer Stufe der Aufnahmebohrung 18 im Ventilträger 6 ab, so daß der unterhalb der Schulter 22 gelegene, im Durchmesser verkleinerte Gehäuseabschnitt des Filtertopfes 28, der ein großzügig bemessenes Filterelement 27 aufnimmt, frei von radialen Montage- und Haltekräften in der Aufnahmebohrung 18 ruht. Im vorliegenden Ausführungsbeispiel ist das Filterelement 27 als Ringfilter ausgeführt. Selbstverständlich sind hierzu auch weitere Filterbauarten, wie Stab- und Plattenfilter geeignet. A reduced-diameter sleeve section of the stepped valve receptacle body 7 is inserted in sections in a stepped filter bowl 10 such that an axial distance remains between the step 12 facing the filter bowl 10 on the valve seat body 7 and the housing edge 21 of the filter bowl 28 , in which the sealing ring 15 rests elastically clamped , This leads to a particularly simple, yet functional, reliable hydraulic seal between the filter bowl 10 and the valve holder body 7 , so that both the depth of the filter bowl 10 in the valve holder body 7 and thus also the installation dimensions of the filter bowl 28 and of the freely selectable axial distance within certain limits Valve receiving body 7 can be generously tolerated in the stepped receiving bore 18 . The stepped filter bowl 10 is advantageously supported via its outer shoulder 22 on a step of the receiving bore 18 in the valve support 6 , so that the housing section of the filter bowl 28 , which has a smaller diameter and accommodates a generously dimensioned filter element 27 , is located below the shoulder 22 of radial assembly and holding forces in the receiving bore 18 rests. In the present exemplary embodiment, the filter element 27 is designed as a ring filter. Of course, other filter types such as rod and plate filters are also suitable.

Der Filtertopf 10 ist vorteilhaft als von oben in die gestufte Aufnahmebohrung 18 eingesetztes Einlegeteil konzipiert, das somit unabhängig vom Elektromagnetventil in die Aufnahmebohrung 18 eingefügt wird. Das mit dem Ringfiltergehäuse 24 und dem Dichtring 15 versehene Elektromagnetventil folgt der Montage des Filtertopf 10 im Ventilträger 6, wobei die abbildungsgemäße elastische Ovalverformung des Dichtrings 15 durch die mögliche Montagetiefe des Ventilaufnahmekörpers 7 in den Filtertopf 10 bestimmt ist. Die vorgeschlagene Konstruktion als auch die gewählte Anordnung des Filtertopfs 28 führt zu keinen Veränderungen hinsichtlich der Fertigung des Elektromagnetventils, so daß unter der Voraussetzung einer an den Filtertopf 10 angepaßten Aufnahmebohrung 18 nach Wunsch oder Bedarf bestehende, auslaßseitig filterlose Elektromagnetventile der beschriebenen Art im Ventilträger 6 montiert werden können. The filter plug 10 is designed advantageously as a top inserted into the stepped receiving bore 18 insert, which is thus inserted into the bore 18 independently of the electromagnetic valve. The electromagnetic valve provided with the ring filter housing 24 and the sealing ring 15 follows the mounting of the filter bowl 10 in the valve carrier 6 , the elastic oval deformation of the sealing ring 15 shown in the illustration being determined by the possible mounting depth of the valve receiving body 7 in the filter bowl 10 . The proposed construction as well as the selected arrangement of the filter bowl 28 does not lead to any changes with regard to the manufacture of the electromagnetic valve, so that, provided that an accommodating bore 18 adapted to the filter bowl 10 is provided, as desired or required, existing, filterless solenoid valves of the type described described are mounted in the valve carrier 6 can be.

Als wesentliches Merkmal der Erfindung ist zu bemerken, daß in der Aufnahmebohrung 18 als eigenständig handhabbares Einlegeteil ein mit einem Filterelement 27 versehener Filtertopf 10 eingesetzt ist, in dem abschnittsweise ein den Ventilsitz 16 aufweisender Abschnitt des Elektromagnetventils radial geführt ist. As an essential feature of the invention, it should be noted that in the receiving bore 18, as an independently manageable insert, a filter bowl 10 provided with a filter element 27 is inserted, in which a section of the solenoid valve having the valve seat 16 is guided radially.

In dem gezeigten Ausführungsbeispiel ist das mit dem Filtertopf 10 zusammenwirkende Gehäusebauteil infolge des zweiteiligen, aus dem Ventilgehäuse 3 und dem Ventilaufnahmekörper 7 bestehenden Aufbaus durch den Ventilaufnahmekörper 7 dargestellt. Ebenso ist es möglich, das mit dem Filtertopf 10 zusammenwirkende Gehäusebauteil einteilig in Form eines in Richtung des Filtertopfes 10 verlängerten Ventilgehäuses 3 auszuführen, das den Ventilsitz 16 aufnimmt und das anstelle des Ventilaufnahmekörpers 7 unmittelbar im Filtertopf 10 geführt ist.
