A sealing ring (9) is inserted in a peripheral groove formed between the clamping collar and a radially protruding shoulder (8) on the outer wall of the valve housing.

Description

Die Erfindung bezieht sich auf ein Ventil in einem Filter nach dem Oberbegriff des Anspruches 1.The invention relates to a valve in a filter according to the preamble of claim 1.

Derartige Ventile werden als Sicherheits- bzw. Umgehungsventile in Filtern beispielsweise für Brennkraftmaschinen eingesetzt, insbesondere in Flüssigkeitsfiltern, bei denen ein in einem Filtergehäuse angeordnetes Filterelement von dem zu reinigenden Fluid durchströmt und über die Reinseite des Filterelementes wieder abgeleitet wird. Um zu verhindern, dass insbesondere im Falle des Verschmutzens des Filterelementes der Strömungswiderstand durch das Filterelement unzulässig hoch ansteigt, was auf der Rohseite des Filterelementes zu einem Druckstau führen kann, der das Filterelement und gegebenenfalls auch weitere Bauteile des Filters zerstören kann, besitzen derartige Filter ein Sicherheitsventil, welches bei Überschreiten eines Druckgrenzwertes öffnet und die Rohseite unmittelbar mit der Reinseite des Filterelementes verbindet. Derartige Sicherheitsventile sind aus Kostengründen einfach aufgebaut und bestehen üblicherweise aus einem in ein Ventilgehäuse eingesetzten Ventilkörper, welcher auf einer Seite von einer Ventilfeder in seine Dichtposition und auf seiner anderen Seite von dem Druck des zu reinigenden Fluids auf der Rohseite des Filterelementes beaufschlagt wird. Übersteigt der Druck die Schließkraft der Ventilfeder, wird der Ventilkörper in seine Offenposition verstellt und das Fluid kann über das Sicherheitsventil abströmen. Ein solches Ventil wird in US-5975115 offenbart.Such valves are used as safety or bypass valves in filters, for example for internal combustion engines, in particular in liquid filters, in which a filter element arranged in a filter element flows through the fluid to be cleaned and is discharged again via the clean side of the filter element. In order to prevent that in particular in the case of contamination of the filter element, the flow resistance through the filter element increases inadmissibly high, which can lead to a pressure accumulation on the raw side of the filter element, which can destroy the filter element and possibly also other components of the filter, have such a filter Safety valve, which opens when a pressure limit is exceeded and connects the raw side directly to the clean side of the filter element. Such safety valves are simply constructed for cost reasons and usually consist of a valve body inserted in a valve body which is acted upon on one side by a valve spring in its sealing position and on its other side by the pressure of the fluid to be cleaned on the raw side of the filter element. If the pressure exceeds the closing force of the valve spring, the valve body is moved to its open position and the fluid can flow off via the safety valve. Such a valve is in US 5975115 disclosed.

Das Ventilgehäuse besteht bei derartigen, bekannten Sicherheitsventilen üblicherweise aus Aluminium und wird als Presspassung in eine Aufnahmeöffnung im Gehäuse des Filters eingesetzt, das in der Regel ebenfalls aus Aluminium besteht. Auf Grund der Wahl gleichen Materials für das Gehäuse des Filters und für das Ventilgehäuse besitzen beide Bauteile den gleichen Wärmedehnungskoeffizienten, wodurch Spannungen als Folge unterschiedlicher Wärmedehnungen ausgeschlossen sind. Andererseits ist man jedoch bestrebt, aus Kostengründen sowie aus Gründen einer vereinfachten Fertigung Filtergehäuse aus Kunststoff herzustellen, die jedoch nicht dafür geeignet sind, die bei einer Presspassung auftretenden Kräfte aufzunehmen.The valve housing is usually made of aluminum in such known safety valves and is used as a press fit in a receiving opening in the housing of the filter, which is also usually made of aluminum. Due to the choice of the same material for the housing of the filter and the valve housing, both components have the same coefficient of thermal expansion, which stresses are excluded as a result of different thermal expansion. On the other hand, it is desirable, however, for reasons of cost and for reasons of simplified manufacturing filter housing made of plastic, but which are not suitable to absorb the forces occurring during a press fit.

Der Erfindung liegt das Problem zugrunde, mit einfachen Mitteln ein Ventil in einem Filter zu schaffen, das einfach aufgebaut ist und mit geringem Aufwand fest im Filtergehäuse verankert werden kann. Das Ventil soll insbesondere auch in Kunststoff-Filtergehäuse einsetzbar sein.The invention is based on the problem with simple means to provide a valve in a filter that is simple and can be firmly anchored in the filter housing with little effort. The valve should be used in particular in plastic filter housing.

Dieses Problem wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This problem is solved according to the invention with the features of claim 1. The dependent claims indicate expedient developments.

Das Ventilgehäuse des erfindungsgemäßen Ventils besitzt einen gegenüber der Gehäuseaußenwand radial überstehenden und elastisch verformbaren Klemmkragen, welcher zusätzlich zur radialen Komponente auch mit einer axialen Komponente sich über die Gehäuseaußenwand erhebt. Dieser schräg abstehende Klemmkragen ist in der Weise ausgebildet, dass eine in einer Ventillängsebene liegende Tangente an den äußeren Kragenrand mit der Ventillängsachse einen Winkel einschließt, der nicht größer als 90° ist. Auf diese Weise ist sichergestellt, dass das Ventilgehäuse in der Weise in eine Ausnehmung im Filtergehäuse eingeschoben werden kann, dass der Klemmkragen zunächst während der Einschiebebewegung bis zum Erreichen des Endsitzes des Ventiles auf Grund seiner Eigenelastizität radial zusammengedrückt wird, in der Endposition jedoch wieder aufspreizen kann. Beim Aufspreizen wird das Ventil festgeklemmt, wobei sich auf Grund der die Spreizung bewirkenden elastischen Kräfte der Klemmkragen in die umgebende Wandung einkrallen kann. Das Ventil sitzt fest in seinem Sitz, ein unbeabsichtigtes Lösen ist auf Grund der Widerhakenstellung des Klemmkragens praktisch ausgeschlossen. Da es sich jedoch im Unterschied zu Ausführungen aus dem Stand der Technik nicht um eine Presspassung handelt, die durch Einpressen eines Aluminiumventils in ein Aluminiumgehäuse erreicht wird, sondern nunmehr als Folge der Aufspreizung des Klemmkragens bei Erreichen des Endsitzes ein Festkrallen bzw. Eingraben im Bereich einer umlaufenden Linie des Klemmkragens erfolgt, eignet sich dieses zweckmäßig aus Blech gefertigte Ventil in besonderer Weise für den Einsatz in Kunststoff-Filtergehäusen, wobei der gegenüber Metall weichere Kunststoff das Einkrallen des Klemmrandes erleichtert. Auch bei einer wärmebedingten Ausdehnung des das Ventil aufnehmenden Gehäuses bzw. des Ventils gewährleistet die Klemmwirkung einen sicheren Sitz.The valve housing of the valve according to the invention has a relation to the housing outer wall radially projecting and elastically deformable clamping collar which rises in addition to the radial component with an axial component on the housing outer wall. This obliquely protruding clamping collar is formed in such a way that a tangent lying in a longitudinal valve plane to the outer collar edge with the valve longitudinal axis forms an angle not greater than 90 ° is. In this way, it is ensured that the valve housing can be inserted into a recess in the filter housing in such a way that the clamping collar is first radially compressed during insertion movement until it reaches the end seat of the valve due to its inherent elasticity, but in the final position can spread again , When spreading the valve is clamped, which can engage in the surrounding wall due to the spread causing elastic forces of the clamping collar. The valve sits firmly in its seat, unintentional release is virtually eliminated due to the barb position of the clamping collar. However, unlike prior art designs, this is not a press fit achieved by press-fitting an aluminum valve into an aluminum housing, but now, as a result of the spreading of the clamping collar upon reaching the end seat, a solid claw or digging in the area circulating line of the clamping collar, this is suitably made of sheet metal valve in a special way for use in plastic filter housings, the softer metal compared to plastic facilitates the clawing of the clamping edge. Even with a heat-related expansion of the valve receiving housing or the valve, the clamping action ensures a secure fit.

Bei einer Anordnung des Klemmkragens im Bereich der axialen Stirnseite und einer gegenüber der Stirnseite axial zurückversetzten Schulter kann das Ventilgehäuse mit seiner dem Kragen gegenüberliegenden axialen Stirnseite voran in die Gehäuseausnehmung im Filter eingeschoben werden, wobei eine vom Klemmkragen ausgeübte Klemmkraft erst kurz vor Erreichen des endgültigen Sitzes des Ventiles in der Gehäuseausnehmung ausgeübt wird.In an arrangement of the clamping collar in the region of the axial end face and a relation to the end axially recessed shoulder, the valve housing can be inserted with its collar opposite axial end face first in the housing recess in the filter, wherein a force exerted by the clamping collar clamping force until shortly before reaching the final seat of the valve is exerted in the housing recess.

Der Klemmkragen steht beispielsweise in einem 45°-Winkel gegenüber der Mantelfläche des Ventilgehäuses ab. Der Klemmkragen ist vorteilhaft konisch geformt, kann jedoch auch nach außen hin konvex geformt sein, wodurch das Einschieben in die Ausnehmung bzw. Aufnahme im Filtergehäuse erleichtert wird.The clamping collar is, for example, at a 45 ° angle relative to the lateral surface of the valve housing. The clamping collar is advantageously conically shaped, but may also be outwardly convex, whereby the insertion into the recess or recording in the filter housing is facilitated.

Der Klemmkragen befindet sich bevorzugt im Bereich einer axialen Stirnseite des Ventilgehäuses und ist einteilig mit dem Ventilgehäuse ausgebildet. Parallel zum Klemmkragen kann mit geringem axialen Abstand zu diesem versetzt eine umlaufende Schulter an der Mantelfläche der Gehäusewandung vorgesehen sein, wobei der axiale Abschnitt zwischen Klemmkragen und Schulter eine Nut zur Aufnahme eines Dichtringes bildet. Nach dem Einsetzen des Ventiles wird der Klemmkragen radial zusammengepresst, wodurch der in die Nut eingesetzte Dichtring zur Anlage an die Innenwand der das Ventil aufnehmenden Gehäuseausnehmung im Filtergehäuse gelangt und seine Dichtfunktion entfalten kann. Dies wird auch dadurch unterstützt, dass in vorteilhafter Ausführung die Schulter einen etwas geringeren Durchmesser als der unbelastete Klemmkragen aufweist.The clamping collar is preferably in the region of an axial end face of the valve housing and is formed integrally with the valve housing. Parallel to the clamping collar can be provided with a small axial distance to this offset a circumferential shoulder on the lateral surface of the housing, wherein the axial portion between the clamping collar and shoulder forms a groove for receiving a sealing ring. After insertion of the valve, the clamping collar is compressed radially, whereby the sealing ring inserted into the groove comes into contact with the inner wall of the valve receiving housing recess in the filter housing and can develop its sealing function. This is also supported by the fact that in an advantageous embodiment, the shoulder has a slightly smaller diameter than the unloaded clamping collar.

Das Ventilgehäuse einschließlich Klemmkragen, gegebenenfalls auch die Schulter, besteht vorteilhaft aus Blech. Diese kostengünstige Ausführung erlaubt das Erzeugen einer ausreichend hohen, radial nach außen gerichteten Klemmkraft, die vom Klemmkragen erzeugt wird. Bei einem Einsetzen des Ventiles in ein Kunststoff-Filtergehäuse spielen Wärmedehnungen in der Gehäusewandung eine geringere Rolle als bei Ausführungen aus dem Stand der Technik mit Aluminiumgehäusen, so dass bei der Materialwahl für das Ventilgehäuse Kostengesichtspunkte stärker berücksichtigt werden können.The valve housing including clamping collar, possibly also the shoulder, is advantageously made of sheet metal. This low-cost design allows the generation of a sufficiently high, radially outwardly directed clamping force, which is generated by the clamping collar. When the valve is inserted into a plastic filter housing, thermal expansions in the housing wall play a lesser role than in the case of prior art designs with aluminum housings, so that more cost considerations can be taken into account when choosing the material for the valve housing.

Am Klemmkragen kann ein bei der Herstellung erzeugter Stanzgrat im außen liegenden Kragenbereich in sinnvoller Weise für das Verhaken des Klemmkragens bei Erreichen des Sitzes in die umgreifende Wandung der Gehäuseausnehmung ausgenutzt werden.At the clamping collar, a punching burr produced in the manufacture in the outer collar region can be used in a meaningful way for the hooking of the clamping collar upon reaching the seat in the encompassing wall of the housing recess.

Bei dem in Fig. 1 dargestellten Ventil 1 handelt es sich zweckmäßig um ein Sicherheitsventil, welches in einer Ausnehmung 3 in einem Filtergehäuse 2 eingesetzt ist, wobei das Filtergehäuse 2 Teil eines Filters ist, insbesondere eines Flüssigkeitsfilters für ein Kraftfahrzeug, beispielsweise zur Reinigung von Kraftstoff oder von Getriebe- oder Motoröl. Alternativ hierzu kommt aber auch eine Anwendung in einem Luftfilter in Betracht.At the in Fig. 1 valve 1 shown is expediently a safety valve which is inserted in a recess 3 in a filter housing 2, wherein the filter housing 2 is part of a filter, in particular a liquid filter for a motor vehicle, for example for cleaning fuel or gear or engine oil , Alternatively, however, is also an application in an air filter into consideration.

Das Ventilgehäuse 4 des Ventils 1 weist einen geringeren Durchmesser auf als die das Ventil aufnehmende Ausnehmung 3 im Filtergehäuse 2, so dass ein kraftfreies Einschieben des Ventiles in die Ausnehmung möglich ist. Im Ventilgehäuse 4 wird ein Ventilkörper 5 von einer Ventilfeder 6 in Richtung seiner Schließposition beaufschlagt. Der Ventilkörper 5 kann axial von außen von dem zu reinigenden Fluid beaufschlagt werden, wobei der Ventilkörper 5 entgegen der Kraft der auf ihn wirkenden Ventilfeder 6 axial nach oben in seine Öffnungsposition versetzt wird, falls der von dem Fluid ausgeübte Druck die Ventilfederkraft übersteigt.The valve housing 4 of the valve 1 has a smaller diameter than the valve receiving recess 3 in the filter housing 2, so that a force-free insertion of the valve into the recess is possible. In the valve housing 4, a valve body 5 is acted upon by a valve spring 6 in the direction of its closed position. The valve body 5 can be acted upon axially from the outside by the fluid to be cleaned, wherein the valve body 5 is axially against the force of the valve spring acting on him 6 placed in its open position, if the pressure exerted by the fluid pressure exceeds the valve spring force.

Der Ventilkörper 5 liegt benachbart zur offenen axialen Stirnseite im Ventil 1. Im Bereich dieser Stirnseite ist einteilig mit der Gehäusewandung des Ventilgehäuses 4 ein radial und axial überstehender Klemmkragen 7 ausgebildet, welcher Teil der Ventilgehäusewandung ist und gegenüber der Mantelfläche des Ventilgehäuses 4 radial und axial übersteht. Dieser Klemmkragen 7 kann sich im Rahmen seiner Materialelastizität elastisch verformen und wird beim Einschieben des Ventils 1 in die Ausnehmung 3 im Filtergehäuse 2 radial zusammengedrückt, wodurch sich eine radial nach außen wirkende Klemmkraft aufbaut, mit der der äußere Klemmkragenrand gegen die Innenwand der Ausnehmung 3 gedrückt wird. Auf Grund des kleineren Durchmesser des Ventilgehäuses 4 gegenüber der Ausnehmung 3 kann das Ventil 1 problemlos bis zum Erreichen seines Endsitzes in die Ausnehmung eingeschoben werden. Die erforderliche Klemmkraft wird vom Klemmkragen 7 aufgebracht, der in unbelastetem Zustand einen größeren Durchmesser aufweist als die Ausnehmung 3, wobei die Klemmkraft sich linienförmig über den Umfang des Klemmkragens erstreckt. Sofern das Material des Filtergehäuses 2 weich genug ist, wird sich auf Grund der linienförmigen Ausbreitung der Klemmkraft der äußere Rand des Klemmkragens 7 in die Innenwand der Ausnehmung einkrallen, so dass zwischen Klemmkragen und Filtergehäuse ein Formschluss nach Art eines Widerhakens realisiert werden kann.The valve body 5 is adjacent to the open axial end face in the valve 1. In the region of this end face is in one piece formed with the housing wall of the valve housing 4, a radially and axially protruding clamping collar 7, which is part of the valve housing wall and with respect to the lateral surface of the valve housing 4 projects radially and axially. This clamping collar 7 can elastically deform in the context of its material elasticity and is radially compressed during insertion of the valve 1 into the recess 3 in the filter housing 2, whereby a radially outwardly acting clamping force builds up, pressed with the outer clamping collar edge against the inner wall of the recess 3 becomes. Due to the smaller diameter of the valve housing 4 relative to the recess 3, the valve 1 can be easily inserted into the recess until it reaches its final seat. The required clamping force is applied by the clamping collar 7, which in the unloaded state has a larger diameter than the recess 3, wherein the clamping force extends linearly over the circumference of the clamping collar. If the material of the filter housing 2 is soft enough, the outer edge of the clamping collar 7 will cling into the inner wall of the recess due to the linear expansion of the clamping force, so that a form-fitting manner of a barb can be realized between clamping collar and filter housing.

Parallel und mit axialem Abstand zum Klemmkragen 7 ist am Ventilgehäuse 4 eine umlaufende Schulter 8 ausgebildet, die ebenfalls gegenüber der Mantelfläche des Ventilgehäuses 4 radial übersteht. In dem axialen Abschnitt zwischen Klemmkragen 7 und der Schulter 8 ist eine umlaufende Nut gebildet, in die ein Dichtring 9 eingesetzt ist, welcher zweckmäßig als O-Ring ausgeführt ist und Toleranzen sowie unterschiedliche Wärmeausdehnungen von Gehäuse und Ventil überbrücken kann.Parallel to and at an axial distance from the clamping collar 7, a circumferential shoulder 8 is formed on the valve housing 4, which also protrudes radially relative to the lateral surface of the valve housing 4. In the axial section between clamping collar 7 and the shoulder 8, a circumferential groove is formed into which a sealing ring 9 is inserted, which is expediently designed as an O-ring and can bridge tolerances and different thermal expansions of housing and valve.

Wie der vergrößerten Darstellung gemäß Fig. 2 zu entnehmen, ist der auf Grund seiner Eigenelastizität in Pfeilrichtung 12 verschwenkbare Klemmkragen 7 geringfügig konvex ausgebildet, kann gegebenenfalls aber auch rein konisch ausgeführt sein. Gegenüber einer Ventillängsachse 10 schließt eine Tangente 11, die an den äußeren Klemmkragenrand angelegt wird und die in einer die Ventillängsachse einschließenden Ventillängsebene liegt, einen Winkel ein, der in einem Winkelbereich zwischen 0° und 90° liegt und insbesondere bei eingesetztem Ventil beispielsweise etwa 30° beträgt. Bei unbelastetem Klemmkragen 7 liegt der Winkelbereich zwischen 10° und 45° und nimmt einen höheren Wert ein als im eingesetzten Zustand.As the enlarged view according to Fig. 2 is due to its inherent elasticity in the direction of arrow 12 pivotable clamping collar 7 slightly convex, but may optionally be designed purely conical. Opposite a valve longitudinal axis 10 includes a tangent 11 which is applied to the outer clamping collar edge and in a valve longitudinal axis enclosing the valve longitudinal plane, an angle which is in an angular range between 0 ° and 90 ° and, for example, when inserted valve, for example, about 30 ° is. With unloaded clamping collar 7, the angular range is between 10 ° and 45 ° and assumes a higher value than in the inserted state.

Das Ventilgehäuse 4 ist zweiteilig aufgebaut und besitzt einen unteren Abschnitt, an dem der Klemmkragen 7 ausgebildet ist, und eine auf den unteren Abschnitt aufgesetzte Ventilhaube 14, die über einen gebördelten Rand mit dem unteren Abschnitt verbunden ist. Der Klemmkragen 7 steht gegenüber der Gehäuseaußenwand 15 radial nach außen ab.The valve housing 4 is constructed in two parts and has a lower portion on which the clamping collar 7 is formed, and on the lower portion patch valve cover 14, which is connected via a flanged edge to the lower portion. The clamping collar 7 is opposite the housing outer wall 15 radially outward.

Am äußeren Klemmkragenrand befindet sich ein radial überstehender Stanzgrat 13, welcher produktionsbedingt entsteht und vorteilhaft zum Einkrallen in die Wandung im Filtergehäuse 2 benutzt werden kann. Hierdurch wird die Klemmkraft gesteigert.At the outer edge of the clamping collar there is a radially projecting punching burr 13, which arises due to the production and can advantageously be used for clawing into the wall in the filter housing 2. As a result, the clamping force is increased.

An der Innenwand der Ausnehmung 3 ist eine Rippe 16 angeordnet, die einen Anschlag für das Ventil beim Einschieben in die Ausnehmung bildet. Im stirnseitigen Bereich der Ausnehmung 3 ist diese über eine Fase 17 erweitert, wodurch der radial überstehende Klemmkragen 7 leichter zusammengedrückt und besser eingeschoben werden kann; auch der Dichtring 9 kann leichter eingeschoben werden.On the inner wall of the recess 3, a rib 16 is arranged, which forms a stop for the valve when inserted into the recess. In the frontal region of the recess 3, this is extended over a chamfer 17, whereby the radially projecting clamping collar 7 can be compressed more easily and inserted better; Also, the sealing ring 9 can be inserted easily.
