Description

Die Erfindung betrifft eine Ventileinrichtung nach dem Oberbegriff des Hauptanspruchs.The invention relates to a valve device according to the preamble of the main claim.

Der prinzipielle Aufbau solcher Ventileinrichtungen ist allgemein bekannt. Hinsichtlich der Öffnung einer Steuerfläche und somit der fluidischen Verbindung von einem Eintritts- zu einem Austrittskanal des Ventils gibt es insbesondere zwei verschiedene Möglichkeiten, entweder durch Abheben eines Schaltelements von der Steuerfläche wie beim Hubventil oder durch Verdrehen des Schaltelements gegenüber der Steuerfläche, wodurch definierte Durchgangsöffnungen des Schaltelements exakt über die Eintrittskanäle oder den Eintrittskanal des Ventils gelegt werden. Ein solches Drehschieberventil ist beispielsweise in der noch nicht veröffentlichten Patentanmeldung mit dem Aktenzeichen 10101412.0 beschrieben. Die Funktions- und Bauweise von Hubventilen ist allgemein bekannt.The basic structure of such valve devices is well known. With regard to the opening of a control surface and thus the fluidic connection from an inlet to an outlet channel of the valve, there are in particular two different possibilities, either by lifting a switching element of the control surface as in the lifting valve or by turning the switching element relative to the control surface, whereby defined through holes of the Switching element are placed exactly above the inlet channels or the inlet channel of the valve. Such a rotary valve is described for example in the not yet published patent application with the file number 10101412.0. The function and construction of globe valves is well known.

Aus der FR 2 772 429 und der US 4,666,124 sind Tellerventile bekannt, deren Ventilstange über eine Kulisse derart geführt sind, dass sie beim Abheben vom Ventilsitz eine kombinierte Hub- Drehbewegung ausführen. Aus der DE 1990462 ist ein Tellerventil bekannt, das ein Schaltelement aufweist, das ein Querschnitt Kreisförming ist und konturierte Durchgangs offnungen aufweist. Diese Ventile sind jedoch nicht zur geregelten Zuführung des Fluids zu verschiedenen Auslässen geeignet.From the FR 2 772 429 and the US 4,666,124 poppet valves are known, the valve rod are guided over a gate so that they perform a combined lifting rotary motion when lifting from the valve seat. From the DE 1990462 a poppet valve is known which has a switching element which is a cross-section circular and has contoured passage openings. However, these valves are not suitable for controlled delivery of the fluid to different outlets.

Bei einem Drehschieberventil wird eine Ventilstange bzw. -welle als Drehachse des Schaltelementes über ein Antriebsmodul angetrieben. Die Schaltelemente sind in der Regel kreisrund und besitzen Durchgangsöffnungen, die bei Verdrehen mit den Öffnungen einer Steuerfläche korrespondieren und auf diese Art und Weise die fluidische Verbindung zwischen Ventileintrittsöffnung und Ventilaustrittsöffnung herstellen.In a rotary valve, a valve rod or shaft is driven as a rotation axis of the switching element via a drive module. The switching elements are usually circular and have through holes, which when rotated with the openings correspond to a control surface and in this way establish the fluidic connection between the valve inlet opening and the valve outlet opening.

Nachteil eines solchen Drehschieberventils ist der hohe Verschleiß, der durch die Reibung bei der Drehbewegung zwischen Schaltelement und Steuerfläche entsteht. Dies führt zu Leckagen am Ventil und somit zu einer geringeren Lebensdauer. Bei einem Hubventil können Verklebungen, die insbesondere durch den Einfluß von Öl und Kraftstoffadditiven oder auch anderen Verunreinigungen im Abgas in bestimmten Temperaturbereichen entstehen, zu einer Fehlfunktion des Ventils führen. Solche Verklebungen führen auch zu Problemen an Drehschieberventilen, sind hier jedoch durch die scherende Bewegung des Schaltelementes zur Steuerfläche mit geringerer Kraft zu lösen.Disadvantage of such a rotary valve is the high wear caused by the friction during the rotational movement between the switching element and the control surface. This leads to leaks at the valve and thus to a shorter service life. In the case of a lifting valve, adhesions that occur in particular due to the influence of oil and fuel additives or other impurities in the exhaust gas in certain temperature ranges can lead to a malfunction of the valve. Such bonds also lead to problems with rotary valves, but here are solved by the shearing movement of the switching element to the control surface with less force.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Ventileinrichtung mit Verstellvorrichtung zu schaffen, welches den Verschleiß der Dichtflächen reduziert und gleichzeitig Verklebungen beseitigt.The invention is an object of the invention to provide a valve device with adjustment, which reduces the wear of the sealing surfaces and at the same time eliminates adhesions.

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

Hierdurch wird, nachdem ein Spalt durch die kombinierte Hub- Drehbewegung zeugt ist, noch eine weitere Drehbewegung ausgeführt. Hierdurch erhöht sich die Überdeckung der Durchgangsöffnungen im Schaltelement und in der feststehenden Steuerfläche, wodurch die Durchflußmenge verändert und auch geregelt werden kann.As a result, after a gap is witnessed by the combined lifting rotary motion, yet another rotational movement is performed. This increases the coverage of the through holes in the switching element and in the fixed control surface, whereby the flow rate can be changed and also regulated.

Diese Hub- Drehbewegung wird im beschriebenen Anwendungsbeispiel durch eine Kulisse mit einer Führungskontur, die eine Steigung enthält, und einem in der Führungskontur zwangsgeführten Knebel, der fest mit der Ventilstange verbunden ist, realisiert. Durch Drehen der Ventilstange bzw. der Drehachse und damit des fest verbundenen Schaltelementes über einen Antrieb kann nun das Ventil geöffnet bzw. geschlossen werden.This lifting rotary motion is realized in the application example described by a backdrop with a guide contour containing a slope, and a forcibly guided in the guide contour gag, which is fixedly connected to the valve stem realized. By turning the valve rod or the axis of rotation and thus the permanently connected switching element via a drive, the valve can now be opened or closed.

Durch eine umlaufende Dicht- und Schabkante um die Durchgangsöffnungen des Schaltelementes können nun durch die Drehbewegung entstehende Verklebungen scherend gelöst und gleichzeitig durch die Hubbewegung ein permanentes Reiben zwischen der Schabkante und der Steuerfläche verhindert werden, was den Verschleiß im Vergleich zu einem üblichen Drehschieberventil deutlich reduziert. Auf diese Weise können also die Vorteile des Hubventils, insbesondere der geringe Verschleiß, mit den Vorteilen des Drehschieberventils, insbesondere das mögliche Abscheren von Verklebungen, miteinander kombiniert werden.By a circumferential sealing and scraping edge around the through holes of the switching element now resulting from the rotational movement bonds shearing solved and simultaneously by the lifting movement a permanent rubbing between the scraping edge and the control surface can be prevented, which significantly reduces the wear compared to a conventional rotary valve. In this way, therefore, the advantages of the lift valve, in particular the low wear, with the advantages of the rotary valve, in particular the possible shearing off of bonds, can be combined.

Um die Durchgangsöffnungen am Schaltelement befinden sich Schabkanten, die beim Schließen des Ventils durch die Hub- Drehbewegung mögliche Verschmutzungen im Dichtbereich wegschieben und somit die Dichtflächen reinigen. Eine direkt an die Schabkante anschließende Dichtkante erzielt die Dichtwirkung zwischen dem Schaltelement und der Steuerfläche. Auch eine Kante, die Dicht- und Schabfunktion kombiniert ist vorstellbar.To the through holes on the switching element are scraper edges, which push away possible dirt in the sealing area when closing the valve by the lifting rotary motion and thus clean the sealing surfaces. A sealing edge directly adjoining the scraping edge achieves the sealing effect between the switching element and the control surface. Even an edge that combines the sealing and scraping function is conceivable.

Ein Schließen des Ventils bei einer auftretenden Fehlfunktion des Systems kann durch eine Rückdrehfeder an der Kulisse sichergestellt werden.Closing the valve in the event of a malfunction of the system can be ensured by a return spring on the gate.

Ein Ausführungsbeispiel einer solchen Ventileinrichtung mit Verstellvorrichtung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of such a valve device with adjusting device is shown in the drawing and will be described below.

Figur 1 zeigt eine perspektivische Ansicht der Ventileinrichtung mit Verstellvorrichtung in vollständig geöffneter Stellung. FIG. 1 shows a perspective view of the valve device with adjusting device in the fully open position.

Figur 2 zeigt eine perspektivische Darstellung der Unterseite des Schaltelementes sowie einen geschnittenen Teil der Steuerfläche. FIG. 2 shows a perspective view of the underside of the switching element and a cut part of the control surface.

Die in den Figuren 1 und 2 dargestellte erfindungsgemäße Ventileinrichtung mit Verstellvorrichtung befindet sich üblicherweise innerhalb eines hier nicht dargestellten Ventilgehäuses. Eine Ventilstange bzw. -welle 1, die sich im Ventilgehäuse befindet, ist an ihrer ersten Seite fest mit einem Schaltelement 2, an ihrem zweiten Ende mit einem hier nicht dargestellten Antrieb, in der Regel ein Elektromotor, verbunden, der das Schaltelement 2 über die Ventilstange 1 in Drehung setzt. Das Schaltelement 2 weist Durchgangsöffnungen 3 auf, durch die ein Fluid bei geöffneter Stellung des Ventils strömen kann. Am oberen Ende der Ventilstange 1 befindet sich eine Bohrung 4, in die ein Knebel 5 mittels Preßsitz gesteckt ist. Dieser Knebel 5 greift formschlüssig in zwei Führungskonturen 6 einer Kulisse 7 ein, die im vorliegenden Anwendungsbeispiel die Form eines Hohlzylinders aufweist.The in the Figures 1 and 2 shown inventive valve means with adjustment is usually located within a valve housing, not shown here. A valve rod or shaft 1, which is located in the valve housing is fixed at its first side with a switching element 2, at its second end with a drive, not shown here, usually an electric motor, connected to the switching element 2 via the Valve rod 1 turns. The switching element 2 has passage openings 3, through which a fluid can flow in the open position of the valve. At the upper end of the valve rod 1 is a hole 4, in which a toggle 5 is inserted by means of a press fit. This gag 5 engages positively in two guide contours 6 a slide 7, which has the shape of a hollow cylinder in the present application example.

Bei Verdrehen der Ventilstange 1 muß der Knebel 5 genau der Kontur 6 folgen und mit ihm auch die Ventilstange 1 bzw. das Schaltelement 2, welches im vorliegenden Fall einen kreisrunden Querschnitt aufweist. Im ersten Bereich 8 weist die Kontur 6 eine zum Schaltelement 2 parallele Form auf, so daß das Schaltelement 2 in diesem ersten Bereich eine reine Drehbewegung ausführt. Im daran anschließenden Bereich 9 weist die Kontur 6 eine umlaufende Steigung zum Schaltelement 2 hin gerichtet auf, so daß das Schaltelement 2 eine kombinierte Dreh- und Hubbewegung ausführt. Als Gegenstück zum Schaltelement 2 befindet sich an der der Ventilstange 1 abgewandten Seite eine Steuerfläche 10, die in der Regel feststehend und mit dem Ventilgehäuse verbunden ist. Diese Steuerfläche 10 weist ebenfalls konturierte Durchgangsöffnungen 13 auf, die mit denen des Schaltelementes 2 korrespondieren. An der Unterseite des Schaltelementes 2 befinden sich Dichtkanten 11 und Schabkanten 12, die die konturierten Durchgangsöffnungen 3 des Schaltelementes 2 umschließen. Bei vollständig geschlossenem Ventil findet keine Überdeckung der Durchgangsöffnungen 3,13 von Schaltelement 2 und Steuerfläche 10 statt und die Dichtung zwischen einer Eintrittsseite und einer Austrittsseite des Ventils findet über diese Dichtkanten 11 statt. Der Knebel 5 befindet sich zu diesem Zeitpunkt am Anschlag des Konturbereiches 9.When turning the valve rod 1, the toggle 5 must follow exactly the contour 6 and with it the valve rod 1 and the switching element 2, which has a circular cross-section in the present case. In the first region 8, the contour 6 has a shape parallel to the switching element 2, so that the switching element 2 performs a pure rotational movement in this first region. In the adjoining region 9, the contour 6 has a circumferential slope to the switching element 2 directed toward, so that the switching element 2 performs a combined rotational and lifting movement. As a counterpart to the switching element 2 is located on the side facing away from the valve rod 1, a control surface 10, which is generally fixed and connected to the valve housing. This control surface 10 also has contoured passage openings 13, which correspond to those of the switching element 2. On the underside of the switching element 2 are sealing edges 11 and scraping edges 12 which surround the contoured through holes 3 of the switching element 2. When the valve is completely closed, there is no overlapping of the passage openings 3, 13 of the switching element 2 and the control surface 10, and the seal between an inlet side and an outlet side of the valve takes place via these sealing edges 11. The toggle 5 is at this time at the stop of the contour area. 9

Beginnt nun die Drehung der Drehachse 1 über den Antrieb folgt der Knebel 5 der Kontur 6 im Bereich 9 und es findet eine kombinierte Hub- Drehbewegung des Schaltelementes 2 statt. Dabei werden durch die Drehbewegung Verunreinigungen über die Schabkanten 12 des Schaltelementes 2 von der Steuerfläche 10 entfernt. Gleichzeitig entsteht ein kleiner Spalt durch das leichte Anheben der Ventilstange 1 mit dem Schaltelement 2 durch die Führungskontur 6, der am größten ist, wenn das Ende des Bereiches 9 durch den Knebel 5 erreicht ist. Durch diese Hubbewegung wird eine zu große Reibung zwischen den Schabkanten 12 des Schaltelementes 2 und der Steuerfläche 10 verhindert. Während der weiteren Drehbewegung der Ventilstange 1 und somit des Schaltelementes 2 in den Bereich 8 der Führungskontur 6, findet eine wachsende Überdeckung der Durchgangsöffnungen 3,13 von Schaltelement 2 und Steuerfläche 10 statt.Now begins the rotation of the axis of rotation 1 via the drive, the toggle 5 follows the contour 6 in the area 9 and there is a combined lifting rotary movement of the switching element 2 instead. In this case, impurities are removed from the control surface 10 via the scraping edges 12 of the switching element 2 by the rotational movement. At the same time, a small gap is created by the slight lifting of the valve rod 1 with the switching element 2 by the guide contour 6, which is greatest when the end of the area 9 is reached by the toggle 5. As a result of this lifting movement, excessive friction between the scraping edges 12 of the switching element 2 and the control surface 10 is prevented. During the further rotational movement of the valve rod 1 and thus of the switching element 2 in the region 8 of the guide contour 6, finds a growing coverage of the through holes 3.13 of switching element 2 and control surface 10 instead.

Sowohl mit dem sich erweiternden Spalt zwischen dem Schaltelement 2 und der Steuerfläche 10 während der kombinierten Hub- Drehbewegung als auch mit steigender Überdeckung der Durchgangsöffnungen 3,13 während der reinen Drehbewegung wächst auch der Fluidstrom von der Eintrittsseite zur Austrittsseite des Ventils. Die Eintrittsseite befindet sich hier an der dem Schaltelement 2 abgewandten Seite der Steuerfläche 10, die Austrittsseite des Ventils an der dem Steuerelement 10 abgewandten Seite des Schaltelementes 2. Je nach Stellung der Drehachse 1 des Ventils kann somit der Volumenstrom des Fluids verändert und bei entsprechender Steuerung des Stellantriebs geregelt werden.
Bei der schließenden Bewegung des Ventils wird die Ventilstange bzw. -welle 1 in umgekehrter Richtung gedreht und führt dementsprechend zunächst eine reine Drehbewegung bei Durchlaufen des Knebels 5 im Bereich 8 und später bei Durchlaufen des Bereichs 9 des Knebels eine kombinierte Hub- Drehbewegung aus. Auch hier werden während der kombinierten Hub- Drehbewegung vor der Berührung der Dichtfläche 11 des Schaltelementes 2 und der Steuerfläche 10 Verunreinigungen von der Steuerfläche 10 durch die Schabkanten 12 des Schaltelementes 2 gelöst.Both with the widening gap between the switching element 2 and the control surface 10 during the combined lifting rotary motion and with increasing coverage of the through holes 3,13 during the pure rotational movement and the fluid flow from the inlet side to the outlet side of the valve increases. The inlet side is located here on the side facing away from the switching element 2 of the control surface 10, the outlet side of the valve on the side facing away from the control element 10 of the switching element 2. Depending on the position of the axis of rotation 1 of the valve thus the volume flow of the fluid can be changed and with appropriate control be controlled by the actuator.
During the closing movement of the valve, the valve rod or shaft 1 is rotated in the reverse direction and accordingly carries out a pure rotary movement when passing through the toggle 5 in the area 8 and later when passing through the area 9 of the toggle from a combined lifting rotary motion. Again, during the combined lifting rotary movement before the contact of the sealing surface 11 of the switching element 2 and the control surface 10 impurities are solved by the control surface 10 by the scraping edges 12 of the switching element 2.

Es sollte klar sein, daß sowohl die Bauform des Ventilgehäuses als auch die Ausgestaltung von Kulisse 7, Führungskontur 6, Ventilstange 1, Schaltelement 2 und Steuerfläche 10 sowie die Art des Antriebs unterschiedlich ausgeführt werden können.It should be clear that both the design of the valve housing and the design of link 7, guide contour 6, valve rod 1, switching element 2 and control surface 10 and the type of drive can be performed differently.
