Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine Ventilklappeneinheit für ein Abflussventil nach dem Oberbegriff von Anspruch 1.The present invention relates to a valve flap unit for a drain valve according to the preamble of claim 1.

STAND DER TECHNIKSTATE OF THE ART

Aus dem Stand der Technik sind Ablaufventile für Waschtische bekannt. Beispielsweise offenbart die EP 0 342 723 oder die FR 1 600 415 A ein Ablaufventil.Drain valves for washbasins are known from the prior art. For example, the EP 0 342 723 or the FR 1 600 415 A a drain valve.

DARSTELLUNG DER ERFINDUNGDISCLOSURE OF THE INVENTION

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine verbesserte Ventilklappeneinheit für ein Ablaufventil eines Sanitärartikels anzugeben. Insbesondere ist es eine Aufgabe der vorliegenden Erfindung, eine Ventilklappeneinheit anzugeben, welche verbesserte Eigenschaften in der Zusammenarbeit mit einem Ventilsitz aufweist.The present invention is based on the object of specifying an improved valve flap unit for a drain valve of a sanitary article. In particular, it is an object of the present invention to specify a valve flap unit which has improved properties in cooperation with a valve seat.

Diese Aufgabe löst der Gegenstand vom Anspruch 1. Demgemäss umfasst eine Ventilklappeneinheit für ein Ablaufventil eines Sanitärartikels, insbesondere eines Waschtisches, ein Supportelement mit einer Lagerstelle und eine Ventileinheit mit einer Lagerachse, einer von der Lagerachse abstehenden Ventilklappe und einen von der Lagerachse abstehenden Betätigungshebel. Die Ventileinheit ist mit der Lagerachse schwenkbar in der Lagerstelle gelagert. Am Supportelement ist mindestens ein mit einem Anschlagsbereich des Betätigungshebels zusammenwirkender Anschlagsabschnitt angeordnet, welcher für den Betätigungshebel einen Anschlag bereitstellt. Der Anschlagsabschnitt und der Anschlagsbereich des Betätigungshebels sind derart ausgebildet, dass eine ferromagnetische Anziehung zwischen Anschlagsabschnitt und Betätigungshebel erfolgt.This object is achieved by the subject matter of claim 1. Accordingly, a valve flap unit for a drain valve of a sanitary article, in particular a washstand, a support element with a bearing point and a valve unit with a bearing axis, a valve flap protruding from the bearing axis and an actuating lever protruding from the bearing axis. The valve unit is pivotably mounted in the bearing with the bearing axis. At least one stop section, which interacts with a stop area of the actuating lever and provides a stop for the actuating lever, is arranged on the support element. The stop section and the stop area of the actuating lever are designed in such a way that a ferromagnetic attraction takes place between the stop section and the actuating lever.

Durch die ferromagnetische Anziehung werden zwei verschiedene Vorteile erzielt. Einerseits wird bei der Bewegung der Ventilklappe auf einen Ventilsitz durch die ferromagnetische Anziehung eine Schliesskraft auf die Ventilklappe bewirkt. Das heisst, die Ventilklappe wird gegen den Ventilsitz gezogen. Andererseits stellt die ferromagnetische Anziehung eine Haltekraft gegen eine Bewegung der Ventilklappe aus der Anschlagslage, in welcher der Betätigungshebel am Anschlagsabschnitt anliegt, bereit.The ferromagnetic attraction provides two different advantages. On the one hand, when the valve flap is moved onto a valve seat, the ferromagnetic attraction produces a closing force on the valve flap. This means that the valve flap is pulled against the valve seat. On the other hand, the ferromagnetic attraction provides a holding force against a movement of the valve flap from the stop position in which the actuating lever rests on the stop section.

Zusammengefasst verharrt die Ventilklappe in der Anschlagslage in einer determinierten Position.In summary, the valve flap remains in the stop position in a determined position.

Die Anschlagslage ist bezüglich der Lage eines Ventilsitzes, der mit der Ventilklappe kontaktiert werden soll, vorzugsweise derart gewählt, dass wenn der Betätigungshebel in der Anschlagslage ist, die Ventilklappe auf dem Ventilsitz aufliegt.With respect to the position of a valve seat which is to be contacted with the valve flap, the stop position is preferably selected such that when the actuating lever is in the stop position, the valve flap rests on the valve seat.

Die Ventilklappe und der Betätigungshebel sind drehfest mit der Lagerachse in Verbindung. Das heisst, dass bei einer Betätigung des Betätigungshebel die Lagerachse zusammen mit der Ventilklappe verschwenkt wird.The valve flap and the actuating lever are connected to the bearing axis in a rotationally fixed manner. This means that when the actuating lever is actuated, the bearing axis is pivoted together with the valve flap.

Vorzugsweise sind zwei Anschlagsabschnitte, nämlich ein erster Anschlagsabschnitt und ein zweiter Anschlagsabschnitt angeordnet, wobei der Betätigungshebel zwischen den beiden Anschlagsabschnitten hin und her bewegbar ist. Liegt der Betätigungshebel am ersten Anschlagsabschnitt an, so befindet sich die Ventilklappe in Kontakt mit dem Ventilsitz. Das Abflussventil ist dicht verschlossen. Liegt der Betätigungshebel am zweiten Anschlagsabschnitt an, so befindet sich die Ventilklappe nicht in Kontakt mit dem Ventilsitz. Das Abflussventil ist demnach offen. Die Ausdrucksweise "hin und her" heisst im Zusammenhang mit der Ventilklappe, dass diese zwischen einer Offenlage und einer Verschlusslage hin und her bewegbar ist.Two stop sections, namely a first stop section and a second stop section, are preferably arranged, the actuating lever being movable back and forth between the two stop sections. If the actuating lever is in contact with the first stop section, the valve flap is in contact with the valve seat. The drain valve is tightly closed. If the actuating lever is in contact with the second stop section, the valve flap is not in contact with the valve seat. The drain valve is therefore open. The expression “back and forth” means in connection with the valve flap that it can be moved back and forth between an open position and a closed position.

Vorzugsweise wird die ferromagnetische Anziehung durch einen Magneten und durch einen ferromagnetischen Bestandteil bereitgestellt. Unter einem ferromagnetischen Bestandteil wird ein Element verstanden, das ganz oder mindestens teilweise aus einem ferromagnetischen Material ist. In einer ersten Variante ist am Betätigungshebel der Magnet angeordnet und der mindestens eine Anschlagsabschnitt ist mindestens teilweise oder ganz aus dem ferromagnetischen Bestandteil. In einer zweiten Variante ist am mindestens einen Anschlagsabschnitt der Magnet angeordnet und der Betätigungshebel ist mindestens teilweise oder ganz aus dem ferromagnetischen Bestandteil.Preferably the ferromagnetic attraction is provided by a magnet and a ferromagnetic component. A ferromagnetic component is understood to mean an element which is wholly or at least partially made of a ferromagnetic material. In a first variant is on the operating lever Arranged magnet and the at least one stop section is at least partially or entirely from the ferromagnetic component. In a second variant, the magnet is arranged on at least one stop section and the actuating lever is at least partially or entirely made from the ferromagnetic component.

Alternativerweise wird die ferromagnetische Anziehung durch zwei Magneten bereitgestellt wird, wobei einer der Magnete am Betätigungshebel und ein anderer der Magnete am Anschlagsabschnitt angeordnet ist.Alternatively, the ferromagnetic attraction is provided by two magnets, one of the magnets being arranged on the actuating lever and another of the magnets being arranged on the stop section.

Vorzugsweise ist die Haltekraft der ferromagnetischen Anziehung zwischen Anschlagsabschnitt und Betätigungshebel zwischen 1,0 und 5,0 Newton, insbesondere zwischen 1, 5 und 3 Newton. Als Haltekraft wird ein Kraftwiderstand verstanden, welcher überwunden werden muss, um den Betätigungshebel aus der Anschlagslage weg zu bewegen. Die Haltekräfte in diesem Bereich haben sich bei Anwendung im Zusammenhang mit Waschtischen als vorteilhaft erwiesen. Dies insbesondere im Zusammenhang mit dem typischen Wasserdruck, der auf die Ventilklappe wirkt. Vorzugsweise weist die Ventilklappe ein Dichtungselement auf, wobei in Einbaulage das Dichtungselement gegen einen Ventilsitz des Ablaufventils gedrückt wird. Hierdurch wird das Ablaufventil entsprechend verschlossen.The holding force of the ferromagnetic attraction between the stop section and the actuating lever is preferably between 1.0 and 5.0 Newtons, in particular between 1.5 and 3 Newtons. A holding force is understood to be a force resistance which must be overcome in order to move the actuating lever away from the stop position. The holding forces in this area have proven to be advantageous when used in connection with washbasins. This is particularly in connection with the typical water pressure that acts on the valve flap. The valve flap preferably has a sealing element, the sealing element being pressed against a valve seat of the drain valve in the installed position. This closes the drain valve accordingly.

Vorzugsweise wird der mindestens eine Anschlagsabschnitt durch ein, insbesondere ferromagnetisches, Anschlagsteil gebildet, welches mit dem Supportelement fest verbunden wird. Das Anschlagsteil kann beispielsweise ein durch einen Stanz- und Umformvorgang hergestelltes Stahlteil sein.The at least one stop section is preferably formed by an, in particular ferromagnetic, stop part which is firmly connected to the support element. The stop part can, for example, be a steel part produced by a stamping and forming process.

Vorzugsweise steht vom Supportelement mindestens ein Nietzapfen und mindestens ein Positionierungszapfen ab, wobei der Nietzapfen nach der Montage des Anschlagsteils verformt wird, so dass das Anschlagsteil fest mit dem Supportelement verbindbar ist.At least one rivet pin and at least one positioning pin preferably protrude from the support element, the rivet pin being deformed after assembly of the stop part so that the stop part can be firmly connected to the support element.

Vorzugsweise ist das Supportelement aus Kunststoff.The support element is preferably made of plastic.

Erfindungsgemäß ist der Anschlagsbereich des Betätigungshebels am freien Ende des Betätigungshebels angeordnet.According to the invention, the stop area of the operating lever is at the free end of the Operating lever arranged.

Vorzugsweise weist der Betätigungshebel weiter eine Anlenkstelle für ein Betätigungselement auf, wobei mit dem Betätigungselement der Betätigungshebel sowie die Lagerachse und die Ventilklappe entsprechend verschwenkbar ist. An der Anlenkstelle ist das Betätigungselement entsprechend angelenkt und kann eine Betätigungskraft auf den Betätigungshebel aufbringen.The actuating lever preferably also has a pivot point for an actuating element, the actuating lever, the bearing axis and the valve flap being correspondingly pivotable with the actuating element. The actuating element is correspondingly articulated at the articulation point and can apply an actuating force to the actuating lever.

Vorzugsweise liegt die Anlenkstelle zwischen der Lagerachse und dem Anschlagsbereich. Hierdurch wird eine besonders gute und austarierte Krafteinleitung erreicht.The articulation point is preferably located between the bearing axis and the stop area. This achieves a particularly good and balanced introduction of force.

Vorzugsweise ist Betätigungselement ein Bowdenzug mit einem Seilzug und einer formstabilen Hülle, wobei der Seilzug auf die Anlenkstelle wirkt und wobei die Hülle an einer Lagerstelle am Supportelement gelagert ist.The actuating element is preferably a Bowden cable with a cable and a dimensionally stable sheath, the cable acting on the articulation point and the sheath being mounted at a bearing point on the support element.

Die Anlenkstelle sowie Lagerstelle zur Lagerung der Hülle am Supportelement sind derart angeordnet, dass der Seilzug zwischen Austrittsstelle aus der Hülle und der Anlenkstelle in der jeweiligen Endlage des Betätigungshebels jeweils im Wesentlichen parallel verläuft. Hierdurch wird erreicht, dass der Seilzug in der jeweiligen Endlage möglichst gerade geführt wird, das heisst, keinen Knick oder ähnliches aufweist. Dies hat den Vorteil, dass die Lebensdauer des Seilzuges erhöht werden kann. Zudem ergeht der Vorteil, dass die Krafteinleitung auf den Betätigungshebel verbessert wird.The articulation point and the bearing point for mounting the cover on the support element are arranged in such a way that the cable pull between the exit point from the cover and the articulation point runs essentially parallel in the respective end position of the actuating lever. This ensures that the cable pull is guided as straight as possible in the respective end position, that is, has no kink or the like. This has the advantage that the service life of the cable pull can be increased. In addition, there is the advantage that the introduction of force to the actuating lever is improved.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

In der Figur 1 wird eine Explosionsdarstellung eines beispielhaften Abflussventils 24 mit einer Ventilklappeneinheit 1 gezeigt. Die Ventilklappeneinheit 1 ist in das Abflussventil 24 einsetzbar ausgebildet.In the Figure 1 FIG. 12 shows an exploded view of an exemplary drain valve 24 a valve flap unit 1 is shown. The valve flap unit 1 is designed to be inserted into the drain valve 24.

Das Abflussventil 24 umfasst einen Abflusskanal 25, einen im Abflusskanal 25 angeordneten Ventilsitz 26 und eine Aufnahme 27 für die Ventilklappeneinheit 1. Weiter umfasst das Abflussventil 24 in der gezeigten Ausführungsform ein Überlaufrohr 28, welches den Ventilsitz 26 entsprechend überbrückt.The drain valve 24 comprises a drain channel 25, a valve seat 26 arranged in the drain channel 25 and a receptacle 27 for the valve flap unit 1. Furthermore, the drain valve 24 in the embodiment shown comprises an overflow pipe 28 which bridges the valve seat 26 accordingly.

Das gezeigte Abflussventil 24 dient insbesondere als Abflussventil für einen Waschtisch. Die Ventilklappeneinheit 1 kann aber auch in andere Abflussventile eingesetzt werden.The drain valve 24 shown serves in particular as a drain valve for a washbasin. The valve flap unit 1 can, however, also be used in other drainage valves.

In der Figur 2 wird eine Schnittdarstellung des Abflussventils 24 gezeigt. Von der Ventilklappeneinheit 1 wird hier im Wesentlichen die Ventilklappe 6 gezeigt. Die Ventilklappe 6 befindet sich hier in einem Abstand zum Ventilsitz 26 und liegt in ihrer Offenstellung. In ihrer Verschlussstellung ist die Ventilklappe 6 dann derart im Kontakt mit dem Ventilsitz 26, dass kein Wasser die Dichtstelle zwischen Ventilsitz 26 und Ventilklappe 6 passieren kann.In the Figure 2 a sectional view of the drain valve 24 is shown. The valve flap 6 of the valve flap unit 1 is essentially shown here. The valve flap 6 is here at a distance from the valve seat 26 and is in its open position. In its closed position, the valve flap 6 is then in contact with the valve seat 26 in such a way that no water can pass the sealing point between the valve seat 26 and the valve flap 6.

In den Figuren 3 und 4 werden zwei perspektivische Ansichten der erfindungsgemässen Ventilklappeneinheit 1 gezeigt. Die Ventilklappeneinheit 1 umfasst im Wesentlichen ein Supportelement 2 und eine Ventileinheit 4. Das Supportelement 2 stellt eine Lagerstelle 3 bereit. Die Ventileinheit 4 umfasst eine Lagerachse 5, eine von der Lagerachse 5 abstehende Ventilklappe 6 und einen von der Lagerachse 6 abstehenden Betätigungshebel 7. Die Ventilklappe 6 und der Betätigungshebel 7 stehen beabstandet zueinander von der Lagerachse 5 weg und sind drehfest zur Lagerachse 5 angeordnet bzw. stehen drehfest mit der Lagerachse 5 in Verbindung. Das heisst, bei einer Betätigung des Betätigungshebels 7 verschwenkt sich die Lagerachse 5 und somit auch die Ventilklappe 6. Die Ventileinheit 4 ist über die Lagerachse 5 schwenkbar in der Lagerstelle 3 des Supportelementes 2 gelagert. Die Lagerstelle 3 ist hier als Öffnung oder Bohrung im Supportelement 2 ausgebildet.In the Figures 3 and 4th two perspective views of the valve flap unit 1 according to the invention are shown. The valve flap unit 1 essentially comprises a support element 2 and a valve unit 4. The support element 2 provides a bearing point 3. The valve unit 4 comprises a bearing shaft 5, a valve flap 6 protruding from the bearing shaft 5 and an actuating lever 7 protruding from the bearing shaft 6. are rotatably connected to the bearing axis 5. This means that when the actuating lever 7 is actuated, the bearing axis 5 and thus also the valve flap 6 pivot. The valve unit 4 is pivotably mounted in the bearing point 3 of the support element 2 via the bearing axis 5. The bearing point 3 is designed here as an opening or bore in the support element 2.

Weiter ist am Supportelement 2 mindestens ein Anschlagsabschnitt 9, 10 angeordnet. In der gezeigten Ausführungsform sind genau zwei Anschlagsabschnitte 9, 10 angeordnet. Diese beiden Anschlagsabschnitte 9, 10 wirken mit einem Anschlagsbereich 8 des Betätigungshebels 7 zusammen. Das heisst, der Anschlagsbereich 8 des Betätigungshebels 7 schlägt an den Anschlagsabschnitt 9, 10 an. Hierdurch wird für den Betätigungshebel 7 durch die Anschlagsabschnitte 9, 10 einen Anschlag bereitgestellt.Furthermore, at least one stop section 9, 10 is arranged on the support element 2. In the embodiment shown, exactly two stop sections 9, 10 are arranged. These two stop sections 9, 10 act with a stop area 8 of the Operating lever 7 together. This means that the stop area 8 of the actuating lever 7 strikes the stop section 9, 10. As a result, a stop is provided for the actuating lever 7 by the stop sections 9, 10.

Der mindestens eine Anschlagsabschnitt 9, 10 des Supportelements 2 und der Anschlagsbereich 8 des Betätigungshebels 7 sind dabei derart ausgebildet, dass eine ferromagnetische Anziehung zwischen Anschlagsabschnitt 9, 10 und Betätigungshebel 7 erfolgt. Diese ferromagnetische Anziehung hat den Vorteil, dass der Betätigungshebel 7, sofern er am Anschlagsabschnitt 9, 10 anschlägt, in seine entsprechenden Lage verharrt. Darüber hinaus kommt es aufgrund der ferromagnetischen Kraft zu einer Anziehung des Betätigungshebels 7 wenn sich dieser an den Anschlagsabschnitten 9, 10 nähert.The at least one stop section 9, 10 of the support element 2 and the stop area 8 of the actuating lever 7 are designed in such a way that a ferromagnetic attraction takes place between the stop section 9, 10 and the actuating lever 7. This ferromagnetic attraction has the advantage that the actuating lever 7, if it strikes the stop section 9, 10, remains in its corresponding position. In addition, due to the ferromagnetic force, the actuating lever 7 is attracted when it approaches the stop sections 9, 10.

Wie bereits erwähnt sind in der gezeigten Ausführungsform zwei Anschlagsabschnitte 9, 10 vorhanden. Es handelt sich dabei um einen ersten Anschlagsabschnitt 9 und einen zweiten Anschlagsabschnitt 10. Der Betätigungshebel 7 lässt sich zwischen diesen beiden Anschlagsabschnitten 9, 10 hin- und her bewegen. Diese Hin- und Herbewegung wird in den Figuren 5 und 6 gezeigt. In der Figur 5 steht der Betätigungshebel 7 derart, dass der Anschlagsbereich 8 mit dem ersten Anschlagsabschnitt 9 im Kontakt steht. In der in Figur 6 gezeigten Stellung liegt der Betätigungshebel 7 derart, dass der Anschlagsbereich 8 mit dem zweiten Anschlagsabschnitt 10 in Kontakt steht. Die erste Position gemäss der Figur 5 kann beispielsweise die Verschlussstellung des Abflussventil 24 sein und die in der Figur 6 gezeigte zweite Position kann beispielsweise in der Offenstellung des Abflussventils 24 sein. Eine umgekehrte Konfiguration wäre auch denkbar.As already mentioned, two stop sections 9, 10 are present in the embodiment shown. These are a first stop section 9 and a second stop section 10. The actuating lever 7 can be moved back and forth between these two stop sections 9, 10. This back and forth movement is in the Figures 5 and 6 shown. In the Figure 5 the actuating lever 7 stands in such a way that the stop region 8 is in contact with the first stop section 9. In the in Figure 6 The position shown, the actuating lever 7 is such that the stop area 8 is in contact with the second stop section 10. The first position according to the Figure 5 can for example be the closed position of the drain valve 24 and that in the Figure 6 The second position shown can be in the open position of the drain valve 24, for example. A reverse configuration would also be conceivable.

Die ferromagnetische Anziehung wird in der gezeigten Ausführungsform durch einen Magneten und durch einen ferromagnetischen Bestandteil bereitgestellt. In der gezeigten Ausführungsform ist am freien Ende 29 des Betätigungshebels 7 ein Magnet 11 angeordnet. Die beiden Anschlagsabschnitte 9, 10 sind Teil des Anschlagsteils 12, welches vorzugsweise aus einem Stahlblech hergestellt wird. Das Anschlagsteil 12 wird dann ebenfalls am Supportelement 2 festgelagert. Der Betätigungshebel 7 selbst ist vorzugsweise aus Kunststoff und weist am freien Ende 29 eine Aufnahme 30 für den Magneten 11 auf. Das Magnet 11 kann dabei in die Aufnahme 30 eingesetzt sein oder aber es kann direkt als Spritzgiessteil durch den Betätigungshebel 7 umspritzt werden.In the embodiment shown, the ferromagnetic attraction is provided by a magnet and a ferromagnetic component. In the embodiment shown, a magnet 11 is arranged at the free end 29 of the actuating lever 7. The two stop sections 9, 10 are part of the stop part 12, which is preferably made from sheet steel. The stop part 12 is then also fixedly mounted on the support element 2. The actuating lever 7 itself is preferably made of plastic and has a receptacle 30 for the magnet 11 at the free end 29. The magnet 11 can be inserted into the receptacle 30 or it can be overmolded directly as an injection-molded part by the actuating lever 7.

Alternativerweise können auch zwei Magnete eingesetzt werden oder aber die Konfiguration kann dahingehend geändert werden, dass der ferromagnetische Bestandteil Teil des Betätigungshebels 7 wird und dass die Magnete Teil des Anschlagteils 12 werden.Alternatively, two magnets can also be used or the configuration can be changed in such a way that the ferromagnetic component becomes part of the actuating lever 7 and that the magnets become part of the stop part 12.

Die Haltekraft der ferromagnetischen Anziehung zwischen Anschlagsabschnitt 9, 10 und Betätigungshebel 7 liegt vorzugsweise zwischen 1,0 und 5,0 Newton, insbesondere zwischen 1,5 und 3 Newton.The holding force of the ferromagnetic attraction between the stop section 9, 10 and the actuating lever 7 is preferably between 1.0 and 5.0 Newtons, in particular between 1.5 and 3 Newtons.

Weiter weist die Ventilklappe 6, wie in den Figuren gezeigt, ein Dichtungselement 23 auf. Das Dichtungselement 23 erstreckt sich hier rund um die eigentliche Ventilklappe 6. In Einbaulage drückt das Dichtungselement 23 gegen den Ventilsitz 26 des Abflussventils 24. Die Lage des entsprechenden Anschlagsabschnittes 9, 10 und des Anschlagsbereich 8 des Betätigungshebels 7 ist bezüglich des Ventilsitzes 26 vorzugsweise derart angeordnet, dass das Dichtungselement 23 immer unter Spannung steht, wenn das Dichtungselement 23 mit dem Ventilsitz 26 in Kontakt steht. Das heisst, die ferromagnetische Anziehungskraft kann als Andrückkraft für das Dichtungselement 23 verwendet werden. Hierdurch kann eine gute Dichtigkeit bereitgestellt werden.As shown in the figures, the valve flap 6 also has a sealing element 23. The sealing element 23 extends around the actual valve flap 6 that the sealing element 23 is always under tension when the sealing element 23 is in contact with the valve seat 26. That is to say, the ferromagnetic attraction force can be used as a pressing force for the sealing element 23. In this way, good tightness can be provided.

Das Anschlagsteil 12 wird mit dem Supportelement 2 fest verbunden. Hierfür weist das Supportelement 2 in der gezeigten Ausführungsform mindestens einen Nietzapfen 13, hier genau einen Nietzapfen 13, und mindestens einen Positionierungszapfen 14, hier zwei Positionierungszapfen 14, auf. Diese Nietzapfen bzw. Positionierungszapfen stehen dabei vom Supportelement 2 weg und das Anschlagsteil 12 weist entsprechende Öffnungen 31 auf, durch welche die besagten Zapfen 13, 14 im montierten Zustand dann hindurchragen. Der Nietzapfen 13 wird nach der Montage des Anschlagsteils 12 entsprechend verformt, so dass das Anschlagsteil 12 fest mit dem Supportelement 2 verbunden ist. Der Nietzapfen 13 ist hier zwischen den beiden Positionierungszapfen 14 angeordnet. Durch diese Anordnung wird eine einfache Positionierung und auch eine feste Verbindung zwischen dem Anschlagsteil 12 und dem Supportelement 2 erreicht.The stop part 12 is firmly connected to the support element 2. For this purpose, the support element 2 in the embodiment shown has at least one rivet pin 13, here precisely one rivet pin 13, and at least one positioning pin 14, here two positioning pins 14. These rivet pins or positioning pins project away from the support element 2 and the stop part 12 has corresponding openings 31 through which the said pins 13, 14 then protrude in the assembled state. The rivet pin 13 is correspondingly deformed after the assembly of the stop part 12, so that the stop part 12 is firmly connected to the support element 2. The rivet pin 13 is arranged here between the two positioning pins 14. This arrangement enables simple positioning and also a firm connection between the stop part 12 and the support element 2.

Der Betätigungshebel 7 weist weiter eine Anlenkstelle 15 für ein Betätigungselement 16 auf. Das Betätigungselement 16 greift dabei an der Anlenkstelle 15 an denThe actuation lever 7 also has an articulation point 15 for an actuation element 16. The actuating element 16 engages at the articulation point 15 on the

Betätigungshebel 7 an und kann über die Anlenkstelle 15 eine entsprechende Betätigungskraft auf dem Betätigungshebel 7 aufbringen. Hierdurch kann der Betätigungshebel 7 dann entsprechend um die Lagerachse 5 verschwenkt werden, was dann auch, wie oben erläutert, die Ventilklappe 6 entsprechend verschwenkt.Actuating lever 7 and can apply a corresponding actuating force to the actuating lever 7 via the articulation point 15. As a result, the actuating lever 7 can then be pivoted accordingly about the bearing axis 5, which then, as explained above, the valve flap 6 correspondingly pivoted.

Die Anlenkstelle 15 liegt in der gezeigten Ausführungsform zwischen der Lagerachse 5 und dem Anschlagsbereich 8, der, wie bereits erwähnt am freien Ende 29 des Betätigungshebels 7 liegt. Das freie Ende liegt demnach gegenüber der Lagerachse 5 und die Anlenkstelle 15 liegt zwischen dem freien Ende 29 und der Lagerachse 5. In der gezeigten Ausführungsform ist das Betätigungselement 17 ein Bowdenzug mit einem Seilzug 17 und einer formstabilen Hülle 18. Der Seilzug 17 wirkt dabei auf die Anlenkstelle 15 bzw. steht mit dieser in Verbindung. Die Hülle 18 ist an einer Lagerstelle 19 am Supportelement 2 fest gelagert.In the embodiment shown, the articulation point 15 lies between the bearing axis 5 and the stop area 8, which, as already mentioned, lies at the free end 29 of the actuating lever 7. The free end is therefore opposite the bearing axis 5 and the articulation point 15 lies between the free end 29 and the bearing axis 5. In the embodiment shown, the actuating element 17 is a Bowden cable with a cable 17 and a dimensionally stable cover 18. The cable 17 acts the articulation point 15 or is connected to it. The sleeve 18 is fixedly mounted at a bearing point 19 on the support element 2.

Die Anlenkstelle 15 sowie die Lagerstelle 19 zur Lagerung der Hülle 18 am Supportelement 2 sind dabei derart angeordnet, dass der Seilzug 17 zwischen der Austrittsstelle 20 aus der Hülle 18 und der Anlenkstelle 15 in der jeweiligen Endlage des Betätigungshebels 7 jeweils parallel zueinander verläuft. Das heisst, der Seilzug 17 wird nicht übermässigen Kräften ausgesetzt. Diese Parallelität wird im Wesentlichen in den Figuren 5 und 6 gezeigt. In diesen Figuren kann die Lage des Seilzugs 17 gut erkannt werden.The articulation point 15 and the bearing point 19 for mounting the cover 18 on the support element 2 are arranged such that the cable 17 between the exit point 20 from the cover 18 and the articulation point 15 in the respective end position of the actuating lever 7 runs parallel to one another. That is, the cable 17 is not exposed to excessive forces. This parallelism is essentially in the Figures 5 and 6 shown. In these figures, the position of the cable 17 can be easily recognized.

Das Supportelement 2 weist im Wesentlichen die Gestalt einer Lagerplatte 21 auf. Bezüglich der Lagerplatte 21 liegt die Ventilklappe 6 auf einer Seite der Lagerplatte 21 und der Betätigungshebel 7 liegt auf der anderen Seite der Lagerplatte 21. In der Lagerplatte 21 ist die Lagerstelle 3 angeordnet und die Lagerachse 5 durchdringt die Lagerstelle 3 der Lagerplatte 21.
