Abstract

A device for mixing gas streams (2,3) esp. of different temps., e.g. combustion air for a combustion engine, has at least two gas channels (4,5) associated with one or more closure elements (27) which are adjustable between open and closed positions, the closure elements being coupled together for coupled movement when more than one closure element is provided. The novelty is that, within the entire adjustment range of the closure element(s), at least one closure element occupies an open position for one of the channels.

Description

Die Erfindung betrifft ein Mischventil für warme und kalte Ansaugluft eines Verbrennungsmotors nach dem Oberbegriff des Patentanspruchs 1 als Zusatz zu der Patentanmeldung P 42 08 616.7.The invention relates to a mixing valve for warm and cold intake air of an internal combustion engine after the Preamble of claim 1 as an addition to the Patent application P 42 08 616.7.

Bei der Ausführung nach der Hauptanmeldung liegen die jeweilige Verschlußfläche der Drehschieberelemente und die einem Drehschieber jeweils zugeordnete Kana­ löffnung jeweils auf konzentrisch zueinander in bezug auf die Drehschieberschwenkachse verlaufenden Mantel­ flächen. Für den Fall, daß die Drehschieber die je­ weils zugeordnete Kanalöffnung in Schließstellung dicht abdecken sollen, bedeutet dies, daß die Ver­ schlußflächen der Drehschieber die jeweiligen Kanal­ ränder möglichst abstandsfrei überstreichen müssen. Ist der Abstand zu groß, ist kein dichter Abschluß in Schließstellung möglich. Ist der Abstand auf der an­ deren Seite sehr gering, kommt es während des Über­ streichens der Kanalöffnung zu unerwünschter Reibung.When executing after the main registration, the respective closure surface of the rotary slide elements and the Kana assigned to a rotary valve each opening concentric with respect to each other jacket running on the rotary slide pivot axis surfaces. In the event that the rotary valve the ever because assigned channel opening in the closed position should cover tightly, this means that the Ver end faces of the rotary valve the respective channel have to paint over the edges as far as possible. If the distance is too large, there is no tight seal in Closed position possible. Is the distance on the whose side is very small, it happens during the over stroking the channel opening to undesired friction.

Hier eine Verbesserung in dem Sinne zu schaffen, daß bei möglichst geringer bzw. fehlender Reibung beim Überstreichen des Drehschieberelementes über die Ka­ nalöffnungsränder dennoch ein dichter Verschluß in der Schließstellung gegeben ist, ist das Problem, mit dem sich die Erfindung beschäftigt.To create an improvement in the sense that with as little or no friction as possible Scanning the rotary slide element over the Ka nal opening edges still a tight seal in the closed position is the problem with  which the invention is concerned with.

Eine Lösung dieses Problems zeigen die kennzeichnen­ den Merkmale des Patentanspruchs 1 auf.The mark show a solution to this problem the features of claim 1.

Eine zweckmäßige Ausgestaltung ist Gegenstand des Pa­ tentanspruchs 2.A practical design is the subject of Pa claim 2.

Ein Ausführungsbeispiel, an dem die Funktion und die Vorteile der Erfindung noch näher dargelegt werden, ist in der Zeichnung dargestellt.An embodiment in which the function and the Advantages of the invention are explained in more detail, is shown in the drawing.

Es zeigen:Show it:

Fig. 1 eine Draufsicht auf ein Mischventil mit zwei unabhängigen Drehschiebersegmenten in unterschiedlichen Verschlußstellungen, Fig. 1 is a plan view of a mixing valve with two independent rotary vane segments in different closure positions,

Fig. 2 eine Ansicht des Mischventiles nach Fig. 1 in Richtung des Pfeiles II. Fig. 2 is a view of the mixing valve of FIG. 1 in the direction of arrow II.

In der Zeichnung deuten die strichpunktierten Linien einen geschlossenen Raum 1 an, der beispielsweise von dem Gehäuse eines Ansaugfilters eines Verbrennungsmo­ tors gebildet sein kann.In the drawing, the dash-dotted lines indicate a closed space 1 , which may be formed, for example, by the housing of an intake filter of a combustion engine.

In diesen geschlossenen Raum 1 münden ein Kaltluftka­ nal 2 und ein Warmluftkanal 3. Um eine Achse 4 sind zwei Drehschiebersegmente 5 und 6 schwenkbar. Von diesen ist das Drehschiebersegment 5 dem Kaltluftka­ nal 2 und Drehschiebersegment 6 dem Warmluftkanal 3 zugeordnet. A cold air duct 2 and a warm air duct 3 open into this closed space 1 . Two rotary slide segments 5 and 6 can be pivoted about an axis 4 . Of these, the rotary valve segment 5 is assigned to the Kaltluftka channel 2 and rotary valve segment 6 to the warm air channel 3 .

Jedes Drehschiebersegment 5, 6 ist für sich unabhän­ gig von dem anderen schwenkbar.Each rotary valve segment 5 , 6 is independently pivotable from the other.

Die Verschlußflächen der beiden Drehschiebersegmente 5, 6 liegen jeweils auf einer Zylinderfläche mit ei­ ner gegenüber der Schwenkachse 4 parallel versetzten Achse 7 bzw. 8. Die Zylinderflächenachsen 7 bzw. 8 sind jeweils derart von der Schwenkachse 4 versetzt, daß in Schließstellung eine dichte Abdeckung der je­ weils zugeordneten Kanalöffnungen gegeben ist, wäh­ rend die Drehschiebersegment-Verschlußfläche in ge­ öffneter Schieberstellung Abstand gegenüber den Kana­ löffnungsrändern aufweist.The closure surfaces of the two rotary slide segments 5 , 6 are each on a cylinder surface with egg ner relative to the pivot axis 4 parallel offset axis 7 and 8th The cylinder surface axes 7 and 8 are each offset from the pivot axis 4 that in the closed position there is a tight cover of the respective assigned channel openings, while the rotary valve segment closure surface in the open slide position has a distance from the channel opening edges.

Mit den Pfeilen A und B sind die jeweiligen Öffnungs­ richtungen für die Drehschiebersegmente 5 und 6 ange­ geben. Der Versatz der Achsen 7 bzw. 8 gegenüber der Schwenkachse 4 ist nun derart, daß die jeweils in Öffnungsdrehrichtung vorne liegende Drehschieberseg­ mentkante 9 einen größeren Abstand von der Schwenkachse 4 besitzt als die in Dreh-Öffnungsrich­ tung jeweils hinten liegende Drehschiebersegmentkante 10. Die Mantelfläche, auf der die Ränder der jeweili­ gen Öffnung der Kanäle 2 bzw. 3 liegen, ist als Zy­ lindermantelfläche ausgebildet, deren Zylinderachse jeweils mit den Achsen 7 bzw. 8 übereinstimmt und zwar bei jeweiliger Verschlußstellung des betreffen­ den Drehschiebersegmentes 5 bzw. 6. Auf diese Weise ergibt sich beim Öffnen eines Drehschiebersegmentes 5 bzw. 6 gegenüber den Rändern der Öffnungen der Kanäle 2 bzw. 3 ein sichelförmiger Abstand, der jeweils im Bereich zwischen den Kanten 9 und 10 von der Kante 10 zur Kante 9 hin radial zur Schwenkachse 4 gesehen zu­ nimmt.The arrows A and B indicate the respective opening directions for the rotary valve segments 5 and 6 . The offset of the axes 7 and 8 with respect to the pivot axis 4 is now such that the front lying in the opening direction of rotation Drehschieberseg mentkante 9 has a greater distance from the pivot axis 4 than the direction of rotation opening direction in each case behind the rotary valve segment edge 10th The lateral surface on which the edges of the respective opening of the channels 2 and 3 are formed is designed as a cylindrical surface, the cylinder axis of which corresponds to the axes 7 and 8 , respectively, with the respective closed position of the rotary slide segment 5 and 6 respectively. In this way, when a rotary slide segment 5 or 6 is opened , there is a crescent-shaped distance from the edges of the openings of the channels 2 or 3 , which in the area between the edges 9 and 10 from the edge 10 to the edge 9 radially to the pivot axis 4 seen increases.

Durch die oben beschriebene Auslegung der Schließflä­ chen der Drehschiebersegmente 5 und 6 mit entspre­ chender Anpassung der Lage der Ränder der Kanalöff­ nungen ist es auf einfache Weise möglich, die Dreh­ schiebersegmente mit Bezug auf die Kanalöffnungsrän­ der berührungsfrei bis in die jeweilige Schließstel­ lung zu verschwenken. In der Schließstellung können die Drehschiebersegmente 5, 6 die Öffnungen dann fest verschließen, da sie in dieser Position auf Anschlag gegenüber den Rändern der Kanalöffnungen drehbar sind.Due to the above-described design of the surfaces of the rotary slide valve segments 5 and 6 with corresponding adjustment of the position of the edges of the channel openings, it is possible in a simple manner to pivot the rotary slide segments with respect to the channel opening rims without contact into the respective closed position. In the closed position, the rotary slide segments 5 , 6 can then firmly close the openings, since in this position they can be rotated against the edges of the channel openings as far as possible.
