Ventil mit einer einen Gasstrom regelnden Klappe Valve with a gas flow regulating flap
Gegenstand der Erfindung ist ein Ventil mit einer einen Gas¬ strom regelnden Klappe, bestehend aus einem Gehäuse mit einem Kanal für den Gasstrom, einer in dem Kanal angeordneten Klappe, wobei die Klappe an einer Antriebswelle derart angeord¬ net ist, dass die Antriebswelle senkrecht zur Längsachse des Kanals in dem Gehäuse gelagert ist, die Klappe derart mittig durchdringt, dass die Klappe in einem Winkel zur Antriebswel¬ le angeordnet ist und dass durch Rotation der Antriebswelle die Klappe zwischen zwei Endstellungen bewegbar ist. Derartige Ventile mit Klappen sind seit langem bekannterThe invention relates to a valve with a gas ¬ flow regulating flap, consisting of a housing with a channel for the gas flow, arranged in the channel flap, wherein the flap angeord ¬ net on a drive shaft is such that the drive shaft perpendicular to Longitudinal axis of the channel is mounted in the housing, the flap penetrates in the middle such that the flap is arranged at an angle to the Antriebswel ¬ le and that by rotation of the drive shaft, the flap between two end positions is movable. Such valves with flaps have long been known
Stand der Technik und werden als Abgasrückführventile oder als Drosselklappenstutzen eingesetzt. Die Antriebswelle durchdringt mittig die Klappe, so dass Klappe und Antriebs¬ welle einen spitzen Winkel bilden. Wird die geöffnete Klappe vom Gasstrom umströmt bilden sich an der Rückseite der Klappe, das heißt in Strömungsrichtung stromabwärts, Verwirbe- lungen. Neben diesen Störungen in der Strömung, bewirken die Verwirbelungen einen Druckabfall. Insbesondere bei Abgasrück- führventilen ist der Druckabfall von Nachteil, da das Abgas anschließend auf einen höheren Druck gebracht werden soll und sich die Druckdifferenz durch den Druckabfall erhöht. State of the art and are used as exhaust gas recirculation valves or as throttle body. The drive shaft penetrates the middle of the flap, so that flap and drive ¬ wave form an acute angle. If the open flap flows around the gas flow, turbulences form on the rear side of the flap, that is to say downstream in the flow direction. In addition to these disturbances in the flow, the turbulence causes a pressure drop. In particular with exhaust gas recirculation valves, the pressure drop is disadvantageous since the exhaust gas is then to be brought to a higher pressure and the pressure difference is increased by the pressure drop.
Der Erfindung liegt die Aufgabe zugrunde, ein Ventil zu schaffen, welches möglichst wenig Verwirbelungen beim Umströ men durch einen Gasstrom erzeugt. The invention has for its object to provide a valve which generates as little turbulence when Umströ men by a gas flow.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Klappe zumindest einen Bereich aufweist, in dem die Klappe kontinuierlich in die Antriebswelle übergeht. According to the invention the object is achieved in that the flap has at least one region in which the flap merges continuously into the drive shaft.
Mit der Schaffung zumindest eines Bereichs mit einem kontinu¬ ierlichen Übergang zwischen Antriebswelle und Klappe wird zum einen durch Materialanhäufung ein Raum ausgefüllt, der bisher Verwirbelungen erzeugt hat, und zum anderen wird durch die Gestaltung eines kontinuierlichen Übergangs das Material so angeordnet, dass eine strömungsgünstige Kontur entsteht, mit der sich Verwirbelungen vermeiden lassen. Mit der Vermeidung von Verwirbelungen lassen sich Druckverluste stromabwärts des Ventils reduzieren und es lässt sich ein wesentlich homogenerer Strömungsverlauf des Gasstroms erzeugen. With the creation of at least a portion with a continu ous ¬ transition between the drive shaft and the flap filling a space by accumulating material, which has so far created turbulences; and secondly, the design of a continuous transition arranges the material in such a way that a streamlined contour is created with which turbulence can be avoided. By avoiding turbulences, pressure losses downstream of the valve can be reduced, and a much more homogeneous flow pattern of the gas flow can be produced.
Die Antriebswelle und die Klappe besitzen unterschiedliche geometrische Grundformen und sie sind zueinander in einem Winkel angeordnet. Insofern besteht eine vorteilhafte Ausge¬ staltung darin, den zumindest einen Bereich, bezogen auf die Längsachse der Antriebswelle, parallel neben der Antriebswel¬ le anzuordnen. The drive shaft and the flap have different geometric basic shapes and they are arranged at an angle to each other. There is therefore an advantageous Substituted ¬ staltung therein, the at least one region with respect to the longitudinal axis of the drive shaft to arrange in parallel next to the Antriebswel ¬ le.
Das Material des zu schaffenden Bereichs kann sowohl ein Kunststoff als auch ein Metall oder eine Metalllegierung sein. In besonders einfacher Weise lässt sich der Bereich gestalten, wenn er aus dem Material der Klappe besteht. Das hat den Vorteil, dass der Bereich im gleichen Arbeitsgang mit der eigentlichen Klappe herstellbar ist. Sofern der Bereich aus einem anderen Material als die Klappe besteht, kann der Be¬ reich separat als Formteil erzeugt werden, welches anschlie¬ ßend an der Klappe und/oder der Antriebswelle befestigt wird. Das nachträgliche Befestigen erlaubt aber auch ein Nachrüsten an bereits bestehenden Ventilen. The material of the area to be created can be both a plastic and a metal or a metal alloy. In a particularly simple manner, the area can be designed if it consists of the material of the flap. This has the advantage that the area can be produced in the same operation with the actual flap. If the area of a different material than the flap, can loading ¬ rich separately produced as a molded part that is subsequently ¬ ßend attached to the flap and / or the drive shaft. The subsequent attachment also allows retrofitting to existing valves.
Einen besonders großen Effekt erzielt der Bereich, wenn er auf der Seite der Klappe angeordnet ist, die bei geschlosse¬ ner Klappe der Strömung abgewandt und bei geöffneter Klappe in Strömungsrichtung hinter der Antriebswelle angeordnet ist. The area achieves a particularly great effect when it is arranged on the side of the flap which, when the flap is closed, faces away from the flow and is arranged behind the drive shaft in the flow direction when the flap is open.
Eine noch weiter verbesserte homogene Strömung mit noch weniger Druckverlusten wird mit einer Klappe erreicht, die einen zweiten Bereich aufweist, in dem die Klappe kontinuierlich in die Antriebswelle übergeht, wobei der zweite Bereich auf der Seite der Klappe angeordnet ist, die der Strömung zugewandt und bei geöffneter Klappe in Strömungsrichtung hinter der Antriebswelle angeordnet ist. Eine besonders strömungsgünstige Klappe wird gemäß der nach¬ folgenden Ausgestaltung dadurch erreicht, wenn die Klappe zwei dritte Bereiche aufweist, welche bei geöffneter Klappe in Strömungsrichtung vor der Antriebswelle angeordnet sind. Damit werden auch die in Strömungsrichtung vor der Antriebs- welle liegenden Bereiche, welche Verwirbelungen erzeugen können, eliminiert. A still further improved homogeneous flow with still less pressure losses is achieved with a flap having a second area in which the flap continuously merges into the drive shaft, the second area on the Side of the flap is arranged, which faces the flow and is arranged with the flap open in the flow direction behind the drive shaft. A particularly favorable flow flap is achieved according to the following ¬ embodiment, when the flap has two third regions, which are disposed with the flap open in the flow direction in front of the drive shaft. This also eliminates the areas in the flow direction in front of the drive shaft, which can generate turbulences.
Die Klappe des Ventils lässt sich besonders kostengünstig fertigen, wenn die Bereiche einteilig mit der Klappe ausge- bildet sind. Die Montage der Klappe in das Ventil gestaltet sich in einfacher Weise, wenn die Klappe eine Aufnahme mit einer Bohrung besitzt, in die die Antriebswelle einsetzbar ist . An mehreren Ausführungsbeispielen wird die Erfindung näher erläutert. Es zeigen in: The flap of the valve can be manufactured particularly inexpensively if the areas are formed integrally with the flap. The assembly of the flap in the valve is designed in a simple manner, when the flap has a receptacle with a bore into which the drive shaft can be inserted.

In Fig. 1 ist ein Ventil im Längsschnitt dargestellt. Es be¬ steht aus einem Gehäuse 1 mit einem Kanal 5, in dem ein Gas- ström geführt ist. In dem Kanal 5 ist ein Ventilsitz 2 für eine Klappe 3 angeordnet. Die Klappe 3 ist mit einer An¬ triebswelle 4 derart verbunden, dass sie bei einer Drehung der Antriebswelle 4 den Kanal freigibt, bzw. verschließt. Die Antriebswelle 4 wird von einem nicht dargestellten Elektromo¬ tor angetrieben und ist hierfür zu beiden Seiten der Klappe 3 im Gehäuse 1 gelagert. Die Antriebswelle 4 durchdringt die Klappe 3 in einem Winkel , so dass sie nicht in der Ebene der Klappe 3 angeordnet ist. Das gezeigte Ventil ist ein Gas- rückführventil in einem Kraftfahrzeug. In Fig. 1, a valve is shown in longitudinal section. It is be ¬ of a housing 1 with a passage 5 in which a gas is guided Ström. In the channel 5, a valve seat 2 for a flap 3 is arranged. The flap 3 is connected to an on ¬ drive shaft 4 so that they on rotation the drive shaft 4 releases the channel, or closes. The drive shaft 4 is driven by a not shown Elektromo ¬ tor and is mounted for this purpose on both sides of the flap 3 in the housing 1. The drive shaft 4 penetrates the flap 3 at an angle so that it is not arranged in the plane of the flap 3. The valve shown is a gas recirculation valve in a motor vehicle.
Figur 2 zeigt die Klappe 3 mit ihrer der Strömung zugewandten Seite. An ihrer Stirnseite 6 ist die Klappe 3 zur Abdichtung am Ventilsitz ausgebildet. Die Klappe weist weiter eine Auf¬ nahme 7 auf, welche einteilig an der Klappe angeformt ist. Die Aufnahme 7 besitzt eine durchgehende Bohrung 8, in der die nicht dargestellte Antriebswelle angeordnet ist. Da die Aufnahme 7 der Antriebswelle zugerechnet werden kann, wird nachfolgend immer auf die Antriebswelle Bezug genommen, auch wenn diese nicht direkt, sondern über eine Aufnahme 7 mit der Klappe 3 verbunden ist. In der Figur 3 ist eine erfindungsgemäße Klappe 3 darge¬ stellt. Der Pfeil zeigt die Strömungsrichtung des Gasstromes an. Ein Bereich 9 ist in Strömungsrichtung gesehen hinter der Aufnahme 7 angeordnet. Der Bereich 9 ist derart ausgebildet, dass die Klappe 3 kontinuierlich in die Aufnahme 7 übergeht. Durch diese Materialanhäufung im Bereich 9 zwischen Antriebswelle und Klappe 3 wird zum einen der bisher vorhandene freie Raum, welcher die Ausbildung von Verwirbelungen bewirkt, eliminiert . Figur 4 zeigt die Klappe 3 in einer Seitenansicht. In Strö¬ mungsrichtung gesehen hinter der Aufnahme 7 ist der Bereich 9 angeordnet, wobei der Bereich 9 eine konvexe Oberfläche be¬ sitzt. Durch die konvexe Oberflächengestaltung des Bereichs 9 wird eine nahezu ungestörte Führung der Strömung nach der Aufnahme 7 erreicht. Die Klappe 3 in Figur 5 weist neben dem Bereich 9 einen zweiten Bereich 9' auf, in dem die Klappe 3 kontinuierlich in die Aufnahme 7 übergeht. Der Bereich 9' ist auf der Seite der Klappe 3 angeordnet, die bei geschlossener Klappe 3 der Strö- mung zugewandt und bei geöffneter Klappe in Strömungsrichtung hinter der Antriebswelle angeordnet ist. Die Strömungsrich¬ tung ist auch hier durch einen Pfeil gekennzeichnet. Bei die¬ ser Klappe 3 sind alle in Strömungsrichtung hinter der Antriebswelle liegenden Totbereiche, in denen sich störende Verwirbelungen bilden können eliminiert. Die Oberfläche der Bereiche 9, 9' ist zum Führen der Strömung konkav ausgebildet . FIG. 2 shows the flap 3 with its side facing the flow. At its end face 6, the flap 3 is designed for sealing on the valve seat. The valve further includes a ¬ On acceptance 7, which is integrally formed on the flap. The receptacle 7 has a through hole 8 in which the drive shaft, not shown, is arranged. Since the receptacle 7 can be attributed to the drive shaft, the drive shaft is always subsequently referred to, even if it is not connected directly, but via a receptacle 7 with the flap 3. In the figure 3 a flap according to the invention is 3 Darge provides ¬. The arrow indicates the flow direction of the gas flow. A region 9 is arranged behind the receptacle 7, viewed in the flow direction. The region 9 is designed such that the flap 3 merges continuously into the receptacle 7. By this accumulation of material in the area 9 between the drive shaft and the flap 3 is on the one hand, the existing free space, which causes the formation of turbulence eliminated. FIG. 4 shows the flap 3 in a side view. In Strö ¬ flow direction viewed behind the seat 7, the area 9 is arranged, wherein the region 9 is seated a convex surface be ¬. Due to the convex surface design of the region 9, a virtually undisturbed guidance of the flow after the intake 7 is achieved. The flap 3 in FIG. 5 has, in addition to the region 9, a second region 9 ', in which the flap 3 merges continuously into the receptacle 7. The region 9 'is arranged on the side of the flap 3 which, with the flap 3 closed, faces the flow and is arranged behind the drive shaft in the flow direction when the flap is open. The flow Rich ¬ tung is characterized here by an arrow. In the ser ¬ flap 3 are all lying in the flow direction behind the drive shaft dead zones in which can form troublesome turbulence eliminated. The surface of the regions 9, 9 'is concave for guiding the flow.
Eine weitere Ausgestaltung der Klappe 3 zeigt Figur 6. Hier- bei weist die Klappe 3 neben den Bereichen 9, 9' zwei dritte Bereiche 9' ' auf, welche bei geöffneter Klappe 3 in Strö¬ mungsrichtung vor der Antriebswelle angeordnet sind. Bei die¬ ser Klappe 3 wurden auch die in Strömungsrichtung vor der Antriebswelle liegenden Bereiche strömungstechnisch optimiert, was eine weitere Reduzierung der Strömungsverluste zur Folge hat . A further embodiment of the flap 3 is shown in FIG 6. here- in, the flap 3 adjacent to the areas 9, 9 ', two third regions 9''which are arranged with the door open 3 in Strö ¬ flow direction in front of the drive shaft. In the ser ¬ flap 3 and the regions located upstream of the drive shaft were optimized flow, resulting in a further reduction in the flow losses.
