Abstract

The device has a movable valve (8) releasing or locking a flow-through cross section (40) in a regulated manner. A transmission drift member (26) is coupled with the valve such that a rotating motion of the member produces a translational movement of the valve. A spring element (44) e.g. return and coil springs, is arranged such that a gear wheel (20) or a turning shaft (16) of a gear unit (6) i.e. spur gear, and the valve are loaded in a closing direction of the valve. The spring element has two spring brackets (42, 48), where one of the brackets is arranged in a slot (50) of the shaft.

Description

Die Erfindung betrifft eine Ventilvorrichtung für eine Verbrennungskraftmaschine mit einem Gehäuse, einem Aktuator, der ein Drehmoment erzeugt, einer Getriebeeinheit, einem translatorisch bewegbaren Ventil, über welches ein Durchströmungsquerschnitt geregelt freigebbar oder verschließbar ist, einem Getriebeabtriebsglied, welches derart mit dem Ventil gekoppelt ist, dass die Drehbewegung des Getriebeabtriebsgliedes eine translatorische Bewegung des Ventils erzeugt und einem Federelement, weiches als Rücksteilfeder dient.The invention relates to a valve device for an internal combustion engine with a housing, an actuator which generates a torque, a transmission unit, a translationally movable valve, via which a flow cross-section is controlled releasable or closable, a transmission output member which is so coupled to the valve, that the rotational movement of the transmission output member generates a translatory movement of the valve and a spring element, which serves as a return spring.

Derartige Ventilvorrichtungen werden beispielsweise als Abgasrückführventile verwendet. Über die zumeist elektromotorische Antriebseinheit wird eine Getriebeeinheit in Drehung versetzt, die ein Kopplungselement aufweist, über welches die rotatorische Bewegung der Zahnräder in eine translatorische Bewegung der Ventilstange umgewandelt wird. Mittels dieser Ventile wird ein Abgasstrom, der vom Abgaskrümmer zum Saugrohr zur Verminderung von Schadstoffemissionen zurückgeführt wird, über einen weiten Bereich geregelt. Bei diesen elektromotorisch angetriebenen Ventilen muss jedoch gemäß Kundenvorgaben sichergestellt werden, dass bei Ausfall des Elektromotors oder Bruch eines Getrieberades eine Rückstellung des Ventils in die geschiossene Stellung erfolgt, um die sichere Funktion des Verbrennungsmotors weiter sicherstellen zu können,Such valve devices are used for example as exhaust gas recirculation valves. About the mostly electric motor drive unit, a gear unit is rotated, which has a coupling element, via which the rotational movement of the gears is converted into a translational movement of the valve stem. By means of these valves, an exhaust gas flow, which is attributed from the exhaust manifold to the intake manifold for the reduction of pollutant emissions, regulated over a wide range. In these electric motor driven valves, however, must be ensured according to customer specifications that in case of failure of the electric motor or breakage of a gear, a provision of the valve is in the geschoossene position to continue to ensure the safe operation of the engine,

So ist aus der EP 1 632 674 A2 ein Abgasrückführventil bekannt, bei dem eine Getriebeeinheit ihn Form eines exzentrischen Kopplungselementes mit einer Kulisse ausgebildet ist, In der Kulisse läuft ein Kugellager, welches wiederum mit einer Ventilstange eines Veritiis verbunden ist. An der Drehachse des Kopplungselementes ist eine Feder angeordnet, die das Koppiungselement derart be!astet, dass das Ventil in eine verschließende Stellung gedreht: wird. Eine zweite Feder ist um die Ventiistange angeordnet und belastet diese ständig gegen die obere Bahn der Kulisse, Ein mehrstufiges Getriebe wird nicht offenbart. Somit werden eine Spielfreiheit zwischen Ventilstange und Kopplungselement und eine Rückstellung des Ventils bei Ausfall des Aktuators mittels zweier Federelenien-te sichergestellt. Die Anzahl der Bauteile ist relativ hoch, so dass Herstell- und Montagekosten steigen. Des Weiteren sind die Stellkräfte der beiden Federn aufeinander und mit dem Aktuator abzustimmen.So is out of the EP 1 632 674 A2 an exhaust gas recirculation valve is known in which a gear unit it is designed in the form of an eccentric coupling element with a backdrop, in the backdrop runs a ball bearing, which in turn connected to a valve stem of a Veritiis. On the axis of rotation of the coupling element, a spring is arranged, the be¬ the Koppiungselement so be! That the valve is rotated in a closing position: is. A second spring is arranged around the Ventiistange and this constantly charged against the upper track of the scenery, a multi-stage transmission is not disclosed. Thus, a backlash between the valve rod and coupling element and a provision of the valve in case of failure of the actuator by means of two Federelenien-te be ensured. The number of components is relatively high, so that manufacturing and assembly costs increase. Furthermore, the actuating forces of the two springs are to be matched to one another and to the actuator.

Es ist daher Aufgabe der Erfindung, eine Ventilvorrichtung zu schaffen, mit der eine Spielfreiheit eines vorgeschalteten Getriebes und eine fail-safe Funktion des Ventils auf einfache Weise sichergestellt werden, wobei die Teileanzafil und der .Montageaufwand im Vergleich zu bekannten Ausführungen minimiert werden sollen.It is therefore an object of the invention to provide a valve device, with a backlash of an upstream transmission and a fail-safe function of the valve can be ensured in a simple manner, the Teileanzafil and .Montageaufwand should be minimized compared to known designs.

Diese Aufgabe wird durch den kennzeichnenden Teil des Hauptanspruchs gelöst.This object is achieved by the characterizing part of the main claim.

Demnach ist das Federelement derart angeordnet, dass einerseits ein Zahnrad oder eine Drehwelle der Getriebeeinheit und andererseits das Ventil in Schließrichtung des Ventils belastet sind. Entsprechend wird für beide Funktionen, also sowohl die Spielfreiheit des Getriebes als auch die fail-safe Funktion des Ventils, lediglich ein einzelnes Bauteil benötigt, welches zusätzlich leicht zu montieren ist.Accordingly, the spring element is arranged such that on the one hand a gear or a rotary shaft of the gear unit and on the other hand, the valve are loaded in the closing direction of the valve. Accordingly, only a single component is needed for both functions, so both the backlash of the transmission and the fail-safe function of the valve, which is also easy to install.

Vorzugsweise ist das Federelement eine Schraubenfeder, welche zwei Federschenkel aufweist, wovon der erste Federschenkel vorgespannt am Ventil angreift und der zweite Federschenkel vorgespannt an eine Drehwelle, auf der ein vorgeschaltetes Zahnrad drehfest angeordnet ist oder an das vorgeschaltete Zahnrad greift, wobei der schraubenförmige Bereich der Schraubenfeder die Drehwelle umgibt. Ein derartiger Aufbau erleichtert die Montage und gibt eine einfache Möglichkeit zur Realisierung der beiden Federfunktionen.Preferably, the spring element is a helical spring, which has two spring legs, of which the first spring leg biased acts on the valve and the second spring leg biased to a rotary shaft on which an upstream gear is arranged rotationally fixed or engages the upstream gear, wherein the helical portion of the coil spring surrounds the rotary shaft. Such a construction facilitates assembly and provides a simple way to realize the two spring functions.

In einer weiterführenden Ausführung der Erfindung ist der zweite Federschenkel in einem Schlitz der Drehwelle angeordnet. So wird eine einfach montierbare Anordnung der Feder erreicht.In a further embodiment of the invention, the second spring leg is arranged in a slot of the rotary shaft. This achieves an easily assembled arrangement of the spring.

In einer bevorzugten Ausführungsform weist das Getriebeabtriebsglied ein Zahnradsegment und einen bezüglich einer Drehachse gegenüberliegenden Betätigungsabschnitt auf, welcher an die Ventilstange oder einen fest mit der Ventilstange verbundenen Bereich greift und mit dem Zahnradsegment um die Drehachse des Zahnradsegmentes drehbar ist, wobei die Drehbewegung des Betätigungsabschnitts die translatorische Bewegung des Ventils verursacht, Die Umwandlung der Drehbewegung des Antriebs in eine transfatorische Bewegung des Ventils wird durch einen derartigen Aufbau vereinfacht. Gleichzeitig ist ein Zugriff zum Montageraum für die Feder vorhanden.In a preferred embodiment, the transmission output member comprises a gear segment and an opposite relative to a rotation axis actuating portion which engages the valve rod or a fixedly connected to the valve rod portion and is rotatable with the gear segment about the axis of rotation of the gear segment, wherein the rotational movement of the actuating portion of the translational Movement of the valve causes, The conversion of the rotational movement of the drive in a transfatory movement of the valve is simplified by such a structure. At the same time there is access to the mounting space for the spring.

In einer weiterführenden Ausführung weist das Zahnradsegment eine Innenverzahnung auf, die mit dem vorgeschalteten Zahnrad kämmt, an dessen Drehwelle oder an dem der zweite Federschenkel vorgespannt ist. Die bedeutet, dass das vorgeschaltete Zahnrad zwischen der ventilstange und dem verzahnten Bereich des als Hebel wirkenden Zahnradsegments angeordnet ist. Ein solches Ventil ist sehr kompakt.In a further embodiment, the gear segment on an internal toothing, which meshes with the upstream gear, is biased on the rotary shaft or on which the second spring leg. This means that the upstream gear is disposed between the valve rod and the toothed portion of the lever-acting gear segment. Such a valve is very compact.

In einer hierzu alternativen Ausführungsform weist das Zahnradsegment eine Außenverzahnung auf, die mit einem vorgeschalteten Zahnrad kämmt, an dessen Drehwelle oder an dem der zweite Federschenkel vorgespannt ist. Dies bedeutet, dass das komplette als Hebel wirkende Zahnsegment zwischen dem vorgeschalteten Zahnrad und der Ventilstange angeordnet ist. Bei Bewegung des Ventils aus dem Stillstand in Schließrichtung entsteht kein Anlagewechsel des Getriebes.In an alternative embodiment, the gear segment has an outer toothing, which meshes with an upstream gear, is biased on the rotary shaft or on which the second spring leg. This means that the complete acting as a lever sector gear between the upstream gear and the Valve rod is arranged. When the valve moves from standstill in the closing direction, there is no system change of the gearbox.

Vorzugsweise ist die Getriebeeinheit ein Stirnradgetriebe, Dieses weist eine geringe Baugröße auf und ist einfach zu montieren. Insbesondere kann auch die Rückstellfeder ohne größeren Aufwand bei einem derartigen Getriebe montiert und gegebenenfalls ausgetauscht werden.Preferably, the gear unit is a spur gear, this has a small size and is easy to install. In particular, the return spring can be mounted without much effort in such a transmission and optionally replaced.

Vorteilhafterweise weist das Stirnradgetriebe ein Antriebszahnrad auf, welches mit dem größeren Zahnrad eines Doppelzahnrades kämmt, welches auf der Drehwelle drehfest angeordnet ist und dessen kleineres Zahnrad mit dem Getriebeabtriebsglied kämmt und als vorgeschaltetes Zahnrad dient. In dieser Bauform wird mit dem Stirnradgetriebe eine hohe Übersetzung erreicht.Advantageously, the spur gear on a drive gear, which meshes with the larger gear of a double gear, which is rotatably mounted on the rotary shaft and whose smaller gear meshes with the transmission output member and serves as upstream gear. In this design, a high gear ratio is achieved with the spur gear.

Es wird somit eine Ventilvorrichtung geschaffen, welche auf einfachste Weise die Funktionen einer zuverlässigen Rückstellung des Ventils und ein Verspannen des Getriebes zur Vermeidung von Getriebespiel sicherstellt. Dies erhöht die Lebensdauer des Getriebes und stellt auf zwei verschiedene Arten die Rückstellung des Ventils sicher. Zusätzlich ist die gesamte Ventilvorrichtung einfach und kostengünstig herstell- und montierbar.It is thus provided a valve device which ensures the simplest way the functions of a reliable return of the valve and a distortion of the transmission to avoid gearing. This increases the life of the gearbox and ensures the return of the valve in two different ways. In addition, the entire valve device is simple and inexpensive to manufacture and assemble.

  • FIG. 2 shows a schematic representation of the erfindungsgernläße valve device of FIG. 1 in side view when closed.
  • FIG. 3 shows a schematic representation of the valve device of FIG. 1 in head view.

Die in den Figuren dargestellte Ventilvorrichtung besteht: aus einem nur ausschnittsweise in Figur 3 dargestellten, üblicherweise mehrteiligen Gehäuse 2, in dem ein Aktuator 4 in Form eines Elektromotors sowie eine über den Elektromotor sntreibbare Getriebeeinheit 6 in Form eines Stirnradgetriebes und ein über die Getriebeeinheit 6 translatorisch bewegbares Ventil 8 angeordnet sind,The valve device shown in the figures consists of a only partially in FIG. 3 shown, usually multi-part housing 2, in which an actuator 4 in the form of an electric motor and a snotreibbare via the electric motor gear unit 6 in the form of a spur gear and a translationally movable via the gear unit 6 valve 8 are arranged

Auf einer Antriebswelle des Aktuators 4 ist ein Antriebszahnrad 10 drehfest angeordnet. Dieses kämmt mit einem größeren Zahnrad 12 eines Doppelzahnrades 14, welches drehfest: auf einer Drehwelle 16 angeordnet ist, die über ein Lager 18 im Gehäuse 2 gelagert ist Ein kleineres Zahnrad 20 des Doppelzahnrades 14 kämmt mit einer Außenverzahnung 22 eines Zahnradsegmentes 24 eines Getriebeabtriebsgliedes 26 und dient somit als vorgeschaltetes Zahnrad zum Getriebeabtriebsglied 26 der Getriebeeinheit 6. Dieses Getriebeabtriebsglied 26 ist auf einer am Gehäuse 2 befestigten Achse 28 gelagert, die als Drehachse für das Getriebeabtriebsglied 26 dient. An der zum Zahnradsegment 24 gegenüberliegenden Seite der Drehachse des Getriebeabtriebsgliedes 26 ist ein Betätigungsabschnitt 30 ausgebildet.On a drive shaft of the actuator 4, a drive gear 10 is arranged rotationally fixed. This meshes with a larger gear 12 of a double gear 14, which is rotationally fixed: is mounted on a rotary shaft 16 which is mounted in the housing 2 via a bearing 18 A smaller gear 20 of the double gear 14 meshes with an external toothing 22 of a gear segment 24 of a transmission output member 26 and thus serves as an upstream gear to the transmission output member 26 of the transmission unit 6. This transmission output member 26 is mounted on a housing 2 fixed to the axis 28, which serves as a rotation axis for the transmission output member 26. On the opposite side to the gear segment 24 of the axis of rotation of the transmission output member 26, an actuating portion 30 is formed.

Der Betätigungsabschnitt 30 kann, wie In vorliegender Darstellung ein Hebelkopf sein, der in eine Ausnehmung 32 greift, welche in einer Ventilstange 34 des Ventils 8 ausgebildet ist. Anstelle dieser Ausnehmung ist auch ein Eingreifen des Betätigungsabschnittes 30 an anderen fest mit dem Ventil 8 verbundenen Bereichen möglich, Dies können beispielsweise zusätzliche, an der Ventilstange 34 befestigte Achsen sein oder der Betätigungsabschnitt 30 liegt in einer einfachsten Ausführung auf dem Ende der Ventilstange 34 auf.The actuating portion 30 may, as in the present illustration, be a lever head which engages in a recess 32 which is formed in a valve rod 34 of the valve 8. Instead of this recess, it is also possible to engage the actuating section 30 at other areas fixedly connected to the valve 8. This may be, for example, additional axes fastened to the valve rod 34 or the actuating section 30 lies in a simplest embodiment on the end of the valve rod 34.

Das Ventil 8 ist; ein bekanntes translatorisch geführtes Hubventil mit der Ventilstange 34 und einem mit der Ventilstange 34 fest verbundenen Ventilschtießglied 36, welches mit einem Ventilsitz 38 zusammenwirkt, der einen Durchströmungsquerschnitt 40 umgibt. Bei Aufliegen des Ventilschließgliedes 36 auf dem Veninsitz 38, der im Strömungsgehäuse ausgebildet ist, wird ein Gasstrom unterbrochen, da der Durchströmungsquerschnitt 40 verschlossen ist.The valve 8 is; a known translationally guided lifting valve with the valve rod 34 and a valve stem 34 fixedly connected Ventilschtießglied 36 which cooperates with a valve seat 38 which surrounds a flow area 40. When the valve closing member 36 rests on the Veninsitz 38, which is formed in the flow housing, a gas flow is interrupted, since the flow cross-section 40 is closed.

An der Ventilstange 34 ist eine weitere Öffnung 41 ausgebildet, durch die erfindungsgemäß ein erster Federschenkel 42 eines als Rückstellfeder dienenden Federelermentes 44 in Form einer Schraubenfeder greift. Ein schraubenförmiger Bereich 46 des Federelementes 44 ist um die Drehwelle 16 gewickelt, während ein zweiter Federschenkel 48 in einem Schlitz 50 der Drehwelle 16 angeordnet ist, Um eine Kollision zwischen dem Getriebeabtriebsglied 26 und dem Federelement 44 zu vermeiden, wiest der erste Federschenkel 42 zwei gleich große jedoch in entgegengesetzte Richtung verlaufende Knicke 52 auf, wie in Figur 3 zu erkennen ist.On the valve rod 34, a further opening 41 is formed, engages by the present invention, a first spring leg 42 serving as a return spring Federelermentes 44 in the form of a helical spring. A helical portion 46 of the spring element 44 is wound around the rotary shaft 16, while a second spring leg 48 is disposed in a slot 50 of the rotary shaft 16. In order to avoid a collision between the transmission output member 26 and the spring member 44, the first spring leg 42 would be equal to two large, but in the opposite direction running kinks 52, as in FIG. 3 can be seen.

Das Federelement 44 wird so montiert, dass bereits in der den Durchströmungsquerschnitt 40 verschließenden Stellung des Ventils 8, eine Kraft durch das Federelement 44 in Schließrichtung auf das Ventil 8 ausgeübt wird. Entsprechend ist das Federelement 44 beim Einsetzen derart zu tordieren, dass der erste Schenkel 42 von unten gegen eine obere Wand der Öffnung 41 drückt und der zweite Schenkel 48 über den Schlitz 50 ein Drehmoment auf die Drehwelle 16 ausübt, weiches in vorliegendem Ausführungsbeispiel im Uhrzeigersinn verläuft und somit ebenfalls das Ventil 8 in Schließrichtung vorspannt. Gleichzeitig wird hierdurch jedoch auch die Verzahnung des kleineren Zahnrades 20 gegen die Flanken der Zähne der Außenverzahnung 22 des Zahnradsegmentes 24 gedrückt. Hierdurch wird das sonst übliche Getriebespiel minimiert, da kein Zahnfiankenwechsel beim Anhalten aus der Bewegung entsteht, In Figur 1 sind mit Pfeilen die entsprechend wirkenden Drehmomente und Kräfte eingezeichnet, die in dieser geschlossenen Stellung innerhalb der Ventilvorrichtung wirken. Der Aktuator 4. ist zu diesem Zeitpunkt nicht bestromt, so dass das Ventil 8 verständig durch Federkraft in der dargestellten Position gehalten wird. Auf die Drehwelle 16 des Doppelzahnrades 14 wirkt ein Drehmoment durch das Federelement 44, welches im Uhrzeigersinn wirkt, Dies bewirkt, dass die Zähne des vorgeschalteten Zahnrades 20 von oben gegen die Zahnflanken des Zahnradsegmentes 24 drücken, welches somit entgegen dem Uhrzeigersinn mit einem Drehmoment belastet wird. Ein gleich wirkendes Drehmoment wirkt somit am Betätigungsabschnitt 30, welcher somit wiederum von unten gegen eine die Ausnehmung 32 in der Ventilstange 34 begrenzende Wand drückt, wodurch die Ventilstange 34 in Schließrichtung belastet wird. Das Federelement belastet die Ventilstange 34 ebenfalls nach oben, so dass das Veritilschließglied 26 durch beide Federteile in Richtung des Ventilsitzes 38 belastet wird. Gleich wirkende Kräfte entstehen in jeder Stellung des Ventils 8 bei nicht betätigtem Aktuator. Somit wird das Ventil 8 durch das Federelement 44 immer in Richtung seines Ventilsitzes belastet.The spring element 44 is mounted in such a way that a force is exerted on the valve 8 in the closing direction already in the position of the valve 8 closing the flow cross-section 40. Accordingly, the spring element 44 is to be twisted during insertion such that the first leg 42 presses from below against an upper wall of the opening 41 and the second leg 48 via the slot 50 a torque on the rotary shaft 16 exerts, which runs in the present embodiment in the clockwise direction and thus also biases the valve 8 in the closing direction. At the same time, however, this also the teeth of the smaller gear 20 is pressed against the flanks of the teeth of the external teeth 22 of the gear segment 24. As a result, the usual gear play is minimized, since no Zahnfiankenwechsel arises when stopping from the movement, In FIG. 1 are shown with arrows the corresponding acting torques and forces acting in this closed position within the valve device. The actuator 4 is not energized at this time, so that the valve 8 is held by spring force in the illustrated position. On the rotary shaft 16 of the double gear 14, a torque acts by the spring element 44, which acts in a clockwise direction, this causes the teeth of the upstream gear 20 press from above against the tooth flanks of the gear segment 24, which is thus loaded in the counterclockwise direction with a torque , An equal acting torque thus acts on the actuating portion 30, which thus in turn presses from below against a recess 32 defining the wall in the valve rod 34, whereby the valve rod 34 is loaded in the closing direction. The spring element also loads the valve rod 34 upward, so that the Veritilschließglied 26 is loaded by both spring parts in the direction of the valve seat 38. Equally acting forces arise in any position of the valve 8 when not actuated actuator. Thus, the valve 8 is always loaded by the spring element 44 in the direction of its valve seat.

In Figur 2 sind die wirkenden Drehmomente beim Öffnen des Ventils 8 eingezeichnet. Das Drehmoment des Aktuators 4 wirkt im Uhrzeigersinn, so dass auf das Doppelzahnrad 14 ein Drehmoment in entgegengesetzter Richtung wirkt. Das Drehmoment des Zahnradsegmentes wirkt nun im Uhrzeigersinn, so dass das Ventil 8 über den Betätigungsabschnitt 30 nach unten in Öffnungsrichtung bewegt wird, Eine entgegengesetzte jedoch kleinere Kraft wirkt in entgegengesetzter Richtung durch den Schenkel 42 des Federelementes 44. Ein entgegengesetztes Drehmoment, welches mit Öffnung des Ventils 8 durch weitere Verdrehung der Feder 44 steigt wirkt ebenfalls auf das Ventil 8. Entsprechend entsteht ein Anlagewechsel der Zahnflanken jeweils im Übergang vom bestromten zum unbestromten Zustand des Aktuators 4. Bei jedem Stillstand des Aktuators entsteht eine definierte Position der Zahnräder zueinander durch das Drehmoment, welches vom Federelement 44 erzeugt wird.In FIG. 2 the effective torques when opening the valve 8 are located. The torque of the actuator 4 acts in a clockwise direction, so that acts on the double gear 14, a torque in the opposite direction. The torque of the gear segment now acts in a clockwise direction, so that the valve 8 is moved via the actuating portion 30 downwardly in the opening direction, an opposite but smaller force acts in the opposite direction by the leg 42 of the spring element 44. An opposite torque, which with opening of Valve 8 increases by further rotation of the spring 44 also acts on the valve 8. Accordingly, a change in the tooth flanks arises in each case in the transition from the energized to the de-energized state of the actuator 4. At each standstill of the actuator creates a defined position of the gears to each other by the torque generated by the spring element 44.

Das dargestellte Ventil ist einfach zu montieren und erwirkt: mittels nur einer Feder sowohl eine Rückstellung der Ventilstange als auch eine Getriebespielminimierung, wodurch die Lebensdauer erhöht wird. Die entstehenden Montage" und Herstellkosten sind sehr gering. Ein derartiges Ventil eignet sich besonders als Abgasrückführventil.The illustrated valve is easy to assemble and provides: a spring return, both valve stem return and gear minimization, increasing life. The resulting assembly and manufacturing costs are very low, and such a valve is particularly suitable as an exhaust gas recirculation valve.

Es sollte deutlich sein, dass verschiedene konstruktive Modifikationen im Vergleich zum beschriebenen Ausführungsbeispiel möglich sind, ohne den Schutzbereich des Hauptanspruchs zu verlassen, So kann das Zahnradsegment als Vollzahnrad, Hohlrad oder innenverzahntes Zahnradsegment ausgeführt werden. Dazu sind verschiedene Ausführungen des Gehäuses bekannt. Die Anordnung des zweiten Federschenkels kann ebenso am Zahnrad selbst erfolgen wie der erste Federschenkel unter ein mit der Ventilstange verbundenes Element greifen kann. Weitere mögliche Änderungen sind dem Fachmann ebenfalls bekannt.It should be clear that various structural modifications compared to the described embodiment are possible without departing from the scope of the main claim, so the gear segment can be performed as a full gear, ring gear or internal gear segment. For this purpose, various embodiments of the housing are known. The arrangement of the second spring leg can also be done on the gear itself as the first spring leg can engage under an element connected to the valve rod. Other possible changes are also known to the person skilled in the art.
