Description

Die Erfindung betrifft einen elektromagnetischen Stellantrieb, insbesondere zum Einsatz bei Ventilen im Kfz-Bereich, wie z. B. Abgasrückführventile, Sekundärluftventile, etc., mit einem Gehäuse, das einen elektrischen Anschlußstecker, ein Magnetjoch, einen Spulenkörper, ein Führungselement, einen Magnetkern und ein Ankerorgan, das mit einem Ventilstellglied zusammenwirkt, aufweist.The invention relates to an electromagnetic actuator, in particular for use in Valves in the automotive sector, such. As exhaust gas recirculation valves, secondary air valves, etc., with a Housing, which has an electrical connector, a magnetic yoke, a bobbin, a Guide element, a magnetic core and an armature member which cooperates with a valve actuator, having.

Ein derartiger Stellantrieb ist beispielsweise aus der DE -A1 - 198 31 140 in Verbindung mit einem Abgasrückführventil bekannt. Dabei wirkt ein zylinderförmiges Ankerorgan als Linearmagnet, der bei Bestromung des Spulenkörpers das Ventilschließglied über ein damit in Wirkverbindung stehendes Ventilstellglied in eine Offen-Stellung des Abgasrückführventiles bewegt. Bei Unterbrechung der Bestromung des Spulenkörpers wird das Ventilschließglied mittels einer Feder, die auf das Ventilstellglied wirkt, in eine Zu-Stellung des Abgasrückführventiles zurück bewegt.Such an actuator is known for example from DE -A1 - 198 31 140 in conjunction with an exhaust gas recirculation valve known. In this case, a cylindrical armature element acts as a linear magnet, when energizing the bobbin, the valve closure member via a so in Operative connection standing valve actuator in an open position of the exhaust gas recirculation valve emotional. When interrupting the energization of the bobbin, the valve closure member by means of a spring which acts on the valve actuator in a closed position of the exhaust gas recirculation valve moved back.

Insbesondere bei Ventilen im Kfz-Bereich, wie z. B. Abgasrückführventile, Sekundärluftventile, etc. kann es durch die hohen thermischen Belastungen, sowie durch Umwelteinflüsse zu Verklebungen, Vereisungen, etc. des Ventilschließgliedes kommen. Das Ventil läßt sich dann nicht mehr öffnen und eine Funktionserfüllung ist dann nicht mehr gewährleistet. Dies hat dann in den meisten Fällen eine kostenintensive Reparatur oder einen Austausch des jeweiligen Ventils zur Folge.Especially for valves in the automotive sector, such. B. exhaust gas recirculation valves, secondary air valves, etc., it may be due to the high thermal loads, as well as by environmental influences Gluing, icing, etc. of the valve closure member come. The valve settles then no longer open and a functional fulfillment is then no longer guaranteed. This then in most cases has a costly repair or replacement of the respective valve result.

Der Erfindung liegt daher die Aufgabe zugrunde, die o. g. Nachteile zu vermeiden.The invention is therefore based on the object o. G. To avoid disadvantages.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Ankerorgan ein erstes und ein zweites Ankerelement aufweist, wobei das zweite Ankerelement scheibenförmig ausgebildet ist und im nichtbestromten Zustand des Stellantriebes durch einen Luftspalt beabstandet vom ersten Ankerelement gelagert ist. This object is achieved in that the anchor member is a first and a second anchor element, wherein the second anchor element is disc-shaped is and spaced in the non-energized state of the actuator by an air gap is mounted from the first anchor element.

Auf diese Weise wirkt das zweite Ankerelement bei Bestromung des Spulenkörpers als Plattenmagnet, der das erste Ankerelement schlagartig anzieht und auf diese Weise eine wesentlich erhöhte Öffnungskraft auf das Ventilschließglied ausübt. Nachdem das erste Ankerelement gegen das zweite Ankerelement anliegt, wirken diese zusammen als ein Ankerorgan in der Art eines Linearmagneten, der das Ventilschließglied auf bekannte Weise öffnet. Damit kann die gleiche Funktion mit einer kleineren Spule gewährleistet werden. Als besonders vorteilhaft hat es sich erwiesen, daß bei entsprechender Auslegung des Spulenkörpers, des Magnetkerns und der Ankerelemente der Luftspalt zwischen 0,1 mm und 2,0 mm beträgt. Eine besonders einfache Konstruktion des elektromagnetischen Stellantriebes ergibt sich, wenn das Ventilstellglied form- oder kraftschlüssig mit dem ersten Ankerelement verbunden ist. Dadurch, daß ein Hülsenelement vorgesehen ist, das form- oder kraftschlüssig mit dem zweiten Ankerelement verbunden ist und beweglich im Magnetkern gelagert ist, wobei das Ventilstellglied verschiebbar durch das Hülsenelement hindurchreicht, wird eine besonders einfache und kompakte Bauweise des elektromagnetischen Stellantriebes realisiert. Dadurch, daß das Hülsenelement ein Ansatzstück aufweist, das in Ausgangslage des zweiten Ankerelementes gegen die Unterseite des Magnetkerns anliegt, ist das zweite Ankerelement in einer bestimmten Ausgangsposition im unbestromten Zustand definiert.In this way, the second anchor element acts when energizing the bobbin as Plate magnet, which attracts the first anchor element abruptly and in this way a significantly increased opening force exerts on the valve closure member. After the first anchor element abuts against the second anchor element, these act together as an anchor member in the manner of a linear magnet which opens the valve closure member in a known manner. Thus, the same function can be ensured with a smaller coil. As special Advantageously, it has been found that with appropriate design of the bobbin, of the magnetic core and the anchor elements of the air gap is between 0.1 mm and 2.0 mm. A particularly simple construction of the electromagnetic actuator results when the valve actuator positively or non-positively connected to the first anchor element is. Characterized in that a sleeve member is provided, the positive or non-positive is connected to the second anchor member and is movably mounted in the magnetic core, wherein the valve actuator slidably extends through the sleeve member becomes a particular realized simple and compact design of the electromagnetic actuator. Characterized in that the sleeve member has an end piece, which in the starting position of the second Anchor element abuts against the underside of the magnetic core, is the second anchor element defined in a certain starting position in the de-energized state.

Auch hat es sich als vorteilhaft erwiesen, daß die Unterseite des Ventilstellgliedes mit dem Ansatzstück abschließt oder darüber hinausreicht, um mit einem geringen Stellweg des Ventilstellgliedes ein Öffnen des Ventilschließgliedes zu gewährleisten. Um eine einwandfreie Führung des Ankerorgans und die nötige magnetische Isolierung zu gewährleisten, können im Führungselement und im Magnetkern eine Lagerbuchse zur beweglichen Lagerung des Ankerorgans angeordnet sein, die gleichzeitig die Ankerelemente magnetisch isoliert.Also, it has proved to be advantageous that the underside of the valve actuator with the Closing piece or beyond reaching, with a small travel of the valve actuator to ensure an opening of the valve closure member. To be a flawless Guidance of the anchor member and to ensure the necessary magnetic isolation can in the guide element and in the magnetic core, a bearing bush for the movable mounting of Anchor organ can be arranged, which simultaneously magnetically isolated the anchor elements.

Darüber hinaus betrifft die Erfindung ein Ventil mit einem elektromagnetischen Stellantrieb, wobei das Ventilstellglied in Wirkverbindung mit einem in einem Ventilgehäuse geführten Ventilschließglied steht, das wiederum über ein Kopplungsstück mit dem Hülsenelement verbunden ist, wobei eine Rückstellfeder auf das Kopplungsstück wirkt und im Ventilgehäuse abgestützt ist, derart, daß das Ventilstellglied, das Ventilschließglied und das Hülsenelement gegen die Bewegungsrichtung im unbestromten Zustand vorgespannt sind.Moreover, the invention relates to a valve with an electromagnetic actuator, wherein the valve actuator is operatively connected to a guided in a valve housing Valve closure member is, in turn, via a coupling piece with the sleeve member is connected, wherein a return spring acts on the coupling piece and in the valve housing is supported, such that the valve actuator, the valve closing member and the sleeve member are biased against the direction of movement in the de-energized state.

Abgasrückführventile, Sekundärluftventile etc. Der elektromagnetische Stellantrieb besteht im wesentlichen aus einem Gehäuse 2 mit einem elektrischen Anschlußstecker 3, über den der Stellantrieb bestromt und gesteuert wird. In dem Gehäuse sind des weiteren auf bekannte Weise ein Magnetjoch 4, ein Spulenkörper 5, ein Führungselement 6, ein Magnetkern 7 und ein Ankerorgan 8, das im vorliegenden Ausführungsbeispiel aus zwei Ankerelementen 9 und 10 besteht, angeordnet. Zur Führung des Ankerorgans 8 sind jeweils im Führungselement und im Magnetkern eine Lagerbuchse 11, 12 vorgesehen. Das erste Ankerelement 9 ist mittels einer Druckfeder 13, die sich am Gehäuse 2 auf bekannte Weise in Bewegungsrichtung abstützt, vorgespannt.Figure 1 shows an electromagnetic actuator 1, which is particularly suitable for use for valves in the automotive sector, such. B. exhaust gas recirculation valves, secondary air valves, etc. The Electromagnetic actuator consists essentially of a housing 2 with a electrical connector 3, via which the actuator is energized and controlled. In the housing are further in a known manner, a magnetic yoke 4, a bobbin 5, a guide element 6, a magnetic core 7 and an anchor member 8, in the present embodiment consists of two anchor elements 9 and 10, arranged. To lead the Anchor organ 8 are each in the guide element and the magnetic core a bearing bush 11, 12 provided. The first anchor element 9 is by means of a compression spring 13, which is located on the housing 2 supported in a known manner in the direction of movement, biased.

Das Ventilstellglied 14, das mit einem in Figur 4 dargestellten Ventilschließglied 15 in Wirkverbindung steht, ist mit dem ersten Ankerelement 9, beispielsweise durch eine Schraubenverbindung, verbunden. Des weiteren reicht das Ventilstellglied 14 durch eine Hülse 16 hindurch und ist in dieser Hülse 16 in Längsrichtung beweglich gelagert. Die Hülse 16 weist ein Ansatzstück 17 auf, das gegen die Unterseite des Magnetkernes 7 anliegt. Auf der gegenübergelegenen Seite der Hülse 16 ist das zweite Ankerelement 10 befestigt. Die Hülse 16 an sich ist im Magnetkern 7 verschiebbar in Längsrichtung gelagert.The valve actuator 14, which with a valve closure member 15 shown in Figure 4 in operative connection is, is with the first anchor element 9, for example by a screw connection, connected. Furthermore, the valve actuator 14 extends through a sleeve 16 therethrough and is movably mounted in this sleeve 16 in the longitudinal direction. The sleeve 16 has a Lug 17, which rests against the underside of the magnetic core 7. On the opposite Side of the sleeve 16, the second anchor member 10 is attached. The sleeve 16 on is slidably mounted in the magnetic core 7 in the longitudinal direction.

Im vorliegenden Ausführungsbeispiel sind das erste Ankerelement 9 und das zweite Ankerelement 10 durch einen Luftspalt mit der Breite 0,5 mm voneinander beabstandet. Des weiteren reicht die Unterseite des Ventilstellgliedes 0,5 mm über die Unterseite des Ansatzstückes 17 der Hülse 16 hinaus.In the present embodiment, the first anchor element 9 and the second anchor element 10 spaced apart by an air gap with the width of 0.5 mm. Of Further, the underside of the valve actuator extends 0.5 mm over the bottom of the extension piece 17 of the sleeve 16 addition.

Figur 2 zeigt den elektromagnetischen Stellantrieb 1 aus Figur 1 kurz nach Einsetzen der Bestromung des Spulenkörpers 5. Das zweite Ankerelement 10, das aufgrund seiner scheibenförmigen Ausführung als Plattenmagnet wirkt, zieht das erste Ankerelement 9 mit sehr hoher Magnetkraft an, und erwirkt damit einen Hub des Ventilstellgliedes 14 von 0,5 mm bei einer wesentlich höheren Öffnungskraft als bei einer Hubvorstellung als Linearmagnet. Figure 2 shows the electromagnetic actuator 1 of Figure 1 shortly after the onset of Energization of the bobbin 5. The second anchor member 10, due to its disc-shaped Execution acts as a plate magnet pulls the first anchor element 9 with a lot high magnetic force, thus obtaining a stroke of the valve actuator 14 of 0.5 mm a much higher opening force than a Hubvorstellung as a linear magnet.

Im weiteren Verlauf des bestromten Zustandes wirkt nun das Ankerorgan 5, bestehend aus den gegeneinander anliegenden Ankerelementen 9 und 11, als Linearmagnet, wobei die Hubvorstellung durch das Ventilstellglied 14 zusammen mit der Hülse 16 erfolgt, wie in Figur 3 dargestellt.In the further course of the energized state now acts the anchor member 5, consisting of the abutting anchor elements 9 and 11, as a linear magnet, wherein the Hubvorstellung by the valve actuator 14 takes place together with the sleeve 16, as shown in FIG 3 shown.

Das Abgasrückführventil 18 weist ein Ventilgehäuse 19 auf, das auf bekannte Weise das Ventilschließglied 15 lagert, das wiederum mit einem an sich bekannten Ventilsitz 20 zusammenwirkt. Eine Rückstellfeder 21, die sich im Ventilgehäuse 19 abstützt, ist gegenüber einem Kopplungsstück 22 vorgespannt. Das Kopplungsstück 22, das auch als Federelement ausgeführt sein kann, verbindet das Hülsenelement 16 mit dem Ventilschließglied 15. Demnach wirkt die Rückstellfeder 21 auf das Kopplungsstück 22 und damit auf das Hülsenelement 16, das Ventilschließglied 15 und das Ventilstellglied 14, die auf diese Weise im unbestromten Zustand in die Ausgangsstellung zurück bewegt werden. Das Gehäuse 2 und das Ventilgehäuse 19 sind im vorliegenden Ausführungsbeispiel durch einen umgerollten Blechring 23 miteinander verbunden.FIG. 4 now shows an exhaust gas recirculation valve in a sectional view with the invention Actuator 1. The exhaust gas recirculation valve 18 has a valve housing 19, the known Way, the valve closing member 15 stores, which in turn with a known valve seat 20 cooperates.
