Eine Drosselklappe der gattungsgemäßen Art ist beispielsweise aus der EP 498 933 A1 bekannt. Diese ist in ein Gehäuse integriert, welches an einem Trägerkörper befestigt werden kann. Das Gehäuse ist nach Art eines Drosselklappenstutzens ausgebildet, d. h. der Stutzen ist einerseits an dem Trägerkörper und andererseits an der Sauganlage einer Brennkraftmaschine befestigt. Die Drosselklappe ist mit einer Achse versehen. An der Achse ist üblicherweise ein Hebel angeordnet, durch welchen die Drosselklappe verstellt werden kann.A throttle valve of the generic type is for example from the EP 498 933 A1 known. This is integrated in a housing, which on a Carrier body can be attached. The housing is like a Throttle body designed, d. H. the nozzle is on the one hand Carrier body and on the other hand on the intake system of an internal combustion engine attached. The throttle valve is provided with an axis. Is on the axis Usually a lever is arranged through which the throttle valve is adjusted can be.

Die mechanische Verstellung einer Drosselklappe ist zwar üblich, allerdings noch bezüglich der erforderlichen Mechanik recht aufwendig und störanfällig. So kommt es insbesondere bei Kraftfahrzeugen gelegentlich zu einem Defekt der Übertragungsmechanik (gerissener Bowdenzug), der zu einem Ausfall des gesamten Fahrzeugs führt.The mechanical adjustment of a throttle valve is common, however still quite complex and prone to failure with regard to the required mechanics. A defect occurs occasionally, particularly in motor vehicles the transmission mechanism (torn Bowden cable), which leads to a failure of the entire vehicle.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Drosseleinrichtung zu schaffen, welche keine Antriebsmechanik benötigt.The object of the invention is therefore to provide a throttle device create which does not require a drive mechanism.

Diese Aufgabe wird ausgehend von dem Oberbegriff des Hauptanspruchs durch dessen kennzeichnende Merkmale gelöst.This task is based on the preamble of the main claim solved by its characteristic features.

Aus der DE 39 05 901 A1 ist zwar eine Klappeneinrichtung bekannt, die über eine Spule verstellt werden kann, diese weist jedoch einen Dauermagneten auf, der zusätzlich an der Klappe angeordnet werden muß. Bei der Erfindung ist dagegen von Vorteil, daß die Drosselklappe wenigstens teilweise permanentmagnetisch ist, so daß zusätzliche Permanentmagnete entfallen können. Außerdem bestehen Drosselklappe und das Gehäuse aus Kunststoff. Damit werden Feldeinflüsse durch Metallteile vermieden und die Effizienz der elektromagnetischen Einrichtung erhöht. Die Drosselklappe ist als Polymermagnet ausgeführt. Dies bedeutet, daß der Kunststoff der Drosselklappe mit magnetischen Teilen dotiert ist und diese magnetischen Teilchen bevorzugt während oder nach dem Herstellen der Drosselklappe, d. h. noch im Spritzgießwerkzeug entsprechend magnetisiert werden können.From DE 39 05 901 A1 a flap device is known, which a coil can be adjusted, but this has a permanent magnet on, which must also be arranged on the flap. In the invention on the other hand, it is advantageous that the throttle valve is at least partially  is permanent magnetic, so that additional permanent magnets are not required can. In addition, the throttle valve and the housing are made of plastic. This prevents field influences from metal parts and the efficiency of the electromagnetic device increased. The throttle valve is as Executed polymer magnet. This means that the plastic of the Throttle valve is doped with magnetic parts and this magnetic Particles preferred during or after the throttle valve is manufactured, i.e. H. can still be magnetized accordingly in the injection mold.

In einer weiteren Ausgestaltung der Erfindung ist die Drosselklappe oder ein Dichtsattel an dem Gehäuse mit einem magnetischen Dichtgummi versehen. Dieses magnetische Dichtgummi hat die Aufgabe, die Drosselklappe in ihrer geschlossenen Stellung zu fixieren und eine geringe Leckluftrate zu erzielen. Selbstverständlich muß das Gegenstück der Dichtfläche mit einem geeigneten Material, d. h. mit einem magnetisch aktiven Kunststoff oder mit einem Dichtgummi mit Magnetpartikeln ausgestattet sein.In a further embodiment of the invention, the throttle valve is or Seal the caliper on the housing with a magnetic sealing rubber. This magnetic sealing rubber has the task of keeping the throttle valve in its to fix the closed position and to achieve a low leakage rate. Of course, the counterpart of the sealing surface must be used with a suitable one Material, d. H. with a magnetically active plastic or with a Seal rubber be equipped with magnetic particles.

Zur Rückstellung der Drosselklappe ist gemäß einer vorteilhaften Ausgestaltung der Erfindung eine Feder vorgesehen. Es besteht auch die Möglichkeit, die Rückstellung mit einer weiteren Magnetspule zu verwirklichen. Eine weitere elektromagnetische Spule kann gemäß einer Weiterbildung der Erfindung zur Sensierung der Winkelstellung der Drosselklappe dienen. Diese Spule ist im Bereich der Drosselklappe angeordnet und erfaßt Änderungen des Luftspaltes, die durch die Änderungen der Stellung der Drosselklappe bewirkt werden.To reset the throttle valve is according to an advantageous Embodiment of the invention provided a spring. There is also Possibility of realizing the reset with another solenoid. A further electromagnetic coil can, according to a further development of the Invention to sense the angular position of the throttle valve. This The coil is arranged in the area of the throttle valve and detects changes in the Air gap caused by changes in the position of the throttle valve will.

Die Drosseleinrichtung kann für eine Brennkraftmaschine konzipiert sein. Selbstverständlich besteht die Möglichkeit, eine solche Drosseleinrichtung auch bei Rohrleitungen, bei Vorrichtungen zum öffnen oder Schließen von Behältern oder in vielen anderen Anwendungsfällen, in denen eine Dosierung oder Abgabe eines Gutes gesteuert werden muß, Anwendung finden. The throttle device can be designed for an internal combustion engine. Of course, there is also the possibility of such a throttle device for pipes, for devices for opening or closing containers or in many other applications where a dosage or Dispensing of a good must be controlled, apply.  

In vorteilhafter Weise kann die Drosseleinrichtung in den Ansaugkanal einer Brennkraftmaschine oder in den Reinluftkanal eines Luftfilters integriert werden. Zusätzliche Bauteile, wie Drosselklappenstutzen oder ähnliches, können somit entfallen.The throttle device can advantageously be inserted into the intake duct Internal combustion engine or be integrated in the clean air duct of an air filter. Additional components such as throttle body or the like can thus omitted.

Diese und andere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.These and other features of preferred developments of the invention go beyond the claims also from the description and the Drawings, the individual features each individually or to several in the form of sub-combinations in the embodiment of Invention and to be realized in other fields and advantageous as well Protectable versions can be represented, for which protection here is claimed.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert. Es zeigt:The invention is explained in more detail below on the basis of exemplary embodiments explained. It shows:

Eine Drosseleinrichtung 10 gemäß Fig. 1 besteht aus einem rohrförmigen Gehäuse 11, welches an den Innenwandungen verlaufende Dichtsattel 12, 13 aufweist. Eine in der Drosseleinrichtung 10 angeordnete Drosselklappe 14 ist auf einer Welle 15 gelagert und liegt in ihrer hier gezeigten Ruhestellung an den Dichtsatteln 12, 13 auf. In dem Gehäuse 11, welches vorzugsweise aus Kunststoff hergestellt ist, befindet sich eine elektrisch ansteuerbare Spule 16, die an den Anschlüssen 17 mit Spannung versorgt wird. Diese Spule ist konzentrisch in dem Gehäuse angeordnet, d. h. sie ist ein Einlegeteil für das Spritzgießwerkzeug des Gehäuses 11.A throttle device 10 according to FIG. 1 consists of a tubular housing 11 which has sealing calipers 12 , 13 running on the inner walls. A throttle valve 14 arranged in the throttle device 10 is mounted on a shaft 15 and rests on the sealing saddles 12 , 13 in the rest position shown here. In the housing 11 , which is preferably made of plastic, there is an electrically controllable coil 16 , which is supplied with voltage at the connections 17 . This coil is arranged concentrically in the housing, ie it is an insert for the injection mold of the housing 11 .

Die Drosselklappe 14 ist mit einer hier nicht dargestellten Feder belastet, welche eine Kraft zum Schließen der Drosselklappe ausübt. Die Drosselklappe 14 ist als Polymermagnet gestaltet, d. h. die Drosselklappe selbst ist ein Permanentmagnet mit quer zur Welle 15 verlaufender Ausrichtung. Wird an die Spule 16 über die Anschlüsse 17 eine Spannung angelegt, dann dreht sich die Drosselklappe je nach Höhe der angelegten Spannung in Richtung des Pfeils 18 und gibt damit den Durchflußquerschnitt frei. Durch entsprechende Gestaltung der permanentmagnetischen Eigenschaften der Drosselklappe kann diese bis in eine 90 Grad-Stellung gedreht werden.The throttle valve 14 is loaded with a spring, not shown here, which exerts a force to close the throttle valve. The throttle valve 14 is designed as a polymer magnet, ie the throttle valve itself is a permanent magnet with an orientation extending transversely to the shaft 15 . If a voltage is applied to the coil 16 via the connections 17 , the throttle valve rotates in the direction of the arrow 18 depending on the level of the voltage applied and thus releases the flow cross section. By appropriately designing the permanent magnetic properties of the throttle valve, it can be rotated to a 90 degree position.

Fig. 2 zeigt die Anordnung eines Dichtelements auf einer Drosselklappe. Der Drosselklappenausschnitt 19, welcher hier dargestellt ist, ist mit einer umlaufenden Vertiefung 20 versehen. In diese wird ein Dichtgummi 21 eingelegt oder im 2K-Spritzgießverfahren auf die Drosselklappe 19 aufgebracht. Dieses Dichtgummi 21 enthält magnetisch aktive Teilchen. In Verbindung mit magnetisierten Dichtsatteln 12, 13 führt die Anwendung des speziellen Dichtgummis 21 dazu, daß in der Ruhestellung der Drosselklappe eine geringe Leckluftrate erzielt wird. Selbstverständlich besteht auch die Möglichkeit, die permanentmagnetischen Eigenschaften der Drosselklappe zur Unterstützung der Abdichtung in der Ruhestellung auszunutzen. Fig. 2 shows the arrangement of a sealing element on a throttle valve. The throttle valve cutout 19 , which is shown here, is provided with a circumferential recess 20 . A sealing rubber 21 is inserted into this or applied to the throttle valve 19 in a two-component injection molding process. This sealing rubber 21 contains magnetically active particles. In connection with magnetized sealing saddles 12 , 13 , the use of the special sealing rubber 21 leads to the fact that a low leakage air rate is achieved in the rest position of the throttle valve. Of course, there is also the possibility of using the permanent magnetic properties of the throttle valve to support the seal in the rest position.

Fig. 3 zeigt eine Spulenanordnung in einer Detaildarstellung. Die Spule 16 ist teilweise in das Gehäuse 11 integriert. An der Innenwandung des Gehäuses 11 ist ein Metallblech 22 angeordnet, welches ferromagnetische Eigenschaften aufweist. Das Metallblech bildet gleichzeitig den Dichtsattel 12. Die Drosselklappe 14 liegt mit ihrer Dichtung 23 in der hier gezeigten Ruhestellung an dem Metallblech 22 an und schließt damit den Drosselquerschnitt zuverlässig ab. Zum Vermeiden des Klemmens der Drosselklappe ist in radialer Richtung zwischen Drosselklappe 14 und Metallblech 22 ein geringer Spalt 24 vorgesehen. Fig. 3 shows a coil arrangement in a detail display. The coil 16 is partially integrated in the housing 11 . A metal sheet 22 , which has ferromagnetic properties, is arranged on the inner wall of the housing 11 . The metal sheet simultaneously forms the sealing saddle 12 . The throttle valve 14 lies with its seal 23 in the rest position shown here on the metal sheet 22 and thus reliably closes off the throttle cross section. To avoid jamming of the throttle valve, a small gap 24 is provided in the radial direction between throttle valve 14 and metal sheet 22 .

Fig. 4 zeigt in einer vergrößerten Darstellung die Einbindung einer Spule 16 in das Gehäuse 11. Die Spule ist nahe des inneren Durchmessers des Gehäuses 11 angeordnet, um Feldverluste zu vermeiden und das Magnetfeld möglichst auf die Drosselklappe 1,4 zu konzentrieren. Fig. 4 shows an enlarged representation of the integration of a coil 16 into the housing 11. The coil is arranged close to the inner diameter of the housing 11 in order to avoid field losses and to concentrate the magnetic field on the throttle valve 1 , 4 as far as possible.

Fig. 5 zeigt eine weitere Variante mit einer Drosselklappe 14 einer in ein Gehäuse 11 eingelegten Spule 16. Fig. 5 shows a further variant with a throttle valve 14 of an inserted into a housing 11 coil 16.

Bei dieser Anordnung ist die Spule derart gewickelt, daß ein radial gerichtetes Magnetfeld erzeugt wird. Zweckmäßigerweise kann an beiden Drosselklappenauflagen eine solche Spule angeordnet sein.With this arrangement, the coil is wound such that a radially directed Magnetic field is generated. Conveniently, both Throttle valve supports such a coil can be arranged.

Ein Dichtgummi (Elastomer), wie beispielsweise in Fig. 5 gezeigt, kann sich auch über die gesamte Oberfläche der Drosselklappe erstrecken. Der Elastomerwerkstoff kann zweckmäßigerweise mit Magnetpartikeln angereichert sein, so daß eine gesamte Magnetisierung der Drosselklappenoberfläche möglich ist. Die Magnetisierung erfolgt während des Herstellvorgangs, d. h. nach dem Auftragen des Elastomerwerkstoffs wird im Werkzeug mittels eines Magnetfeldes die magnetische Ausrichtung der Magnetpartikel vorgenommen.A sealing rubber (elastomer), as shown for example in FIG. 5, can also extend over the entire surface of the throttle valve. The elastomer material can expediently be enriched with magnetic particles, so that an entire magnetization of the throttle valve surface is possible. The magnetization takes place during the manufacturing process, ie after the application of the elastomer material, the magnetic alignment of the magnetic particles is carried out in the tool by means of a magnetic field.
