The interior of the manifold is divided by a wall (4), on either side of which are equal numbers of air outlet apertures. To influence the resonance characteristics of the manifold, the dividing wall has a through aperture which is closable by a throttle valve (5). The throttle valve is rotatably located with its shaft (6) in a housing (7). This housing can be inserted from the exterior in the region of the inlet aperture in the manifold (1), where it is releasably attached by screws (8). USE/ADVANTAGE - To improve dissipation of resonance in an internal combustion engine air intake manifold.

Description

Die Erfindung betrifft einen Luftsammler einer Brenn­ kraftmaschine mit einer den Sammler-Innenraum untertei­ lenden Trennwand, die eine von einem Verschlußorgan ver­ schließbare Durchtrittsöffnung aufweist, wobei das Ver­ schlußorgan mit seinem Gehäuse in den Luftsammler einge­ setzt ist. Ein derartiges Ansaugsystem für Verbrennungs­ motoren ist beispielsweise in der DE 36 28 230 A1 ge­ zeigt.The invention relates to an air collector of a burner Engine with a lower part of the interior of the collector lumbar partition, which ver by a closure member has closable passage opening, the Ver closing organ with its housing in the air collector sets is. Such an intake system for combustion motors is ge for example in DE 36 28 230 A1 shows.

Zur Resonanzaufladung von Brennkraftmaschinen kommen Sauganlagen mit einem Luftsammler nach dem Oberbegriff des Anspruchs 1 zum Einsatz. Das Verschlußorgan ermög­ licht dabei eine Abstimmung auf verschiedene Betriebsbe­ reiche der Brennkraftmaschine. Jedoch wurde durch Unter­ suchung an bekannten Luftsammlern festgestellt, daß ver­ schiedene Luftsammler gleicher Bauart hinsichtlich der erzielbaren Resonanzaufladung von unterschiedlicher Wirk­ samkeit sind.Coming to resonance charging of internal combustion engines Suction systems with an air collector according to the generic term of claim 1 for use. The closure member enables light a coordination to different company areas range of the internal combustion engine. However, by sub search on known air collectors found that ver different air collectors of the same type in terms of achievable resonance charging of different effects are.

Hier Abhilfe zu schaffen und darüber hinaus eine für die Serienfertigung vorteilhafte Gestaltung aufzuzeigen, ist Aufgabe der vorliegenden Erfindung. To remedy this and also one for the Series production shows advantageous design Object of the present invention.  

Diese Aufgabe wird gelöst, indem das Gehäuse des Ver­ schlußorganes lösbar am Luftsammler befestigt und gegen­ über der Trennwand und/oder Sammlerwand mit einer Dich­ tung abgedichtet ist.This problem is solved by the housing of the Ver closing organ releasably attached to the air collector and against over the partition and / or collector wall with a you device is sealed.

Die vorzugsweise umlaufende Dichtung gewährleistet dabei, daß bei verschlossener Durchtrittsöffnung die voneinander getrennten Sammler-Innenräume tatsächlich nicht miteinan­ der in Verbindung stehen. Jedes einzelne Exemplar einer Serie von Luftsammlern weist dann die sichere Trennung der Sammler-Innenräume auf, so daß die oben geschilderten Serienstreuungen, die durch nicht beliebig minimierbare Toleranzen hervorgerufen werden, ausgeschlossen sind. Um dabei einen derartigen Luftsammler einfach fertigen und das Verschlußorgan ggf. austauschen zu können, ist dieses lösbar am Luftsammler befestigt.The preferably circumferential seal ensures that when the passage opening is closed, the one another separate collector interiors actually do not coexist who are communicating. Every single copy of one Series of air collectors then shows the safe separation of the collector's interiors, so that the ones described above Series discrepancies, which cannot be minimized arbitrarily Tolerances are caused are excluded. Around easily manufacture such an air collector and to be able to replace the closure member if necessary is this detachably attached to the air collector.

Besonders sicher ist die Abdichtung, wenn gemäß Anspruch 2 Nuten zur Aufnahme des Dichtprofiles vorgesehen sind. Anspruch 3 schließlich beschreibt eine einfache Gestal­ tung eines als Drosselklappe ausgebildeten Verschlußorga­ nes. Mit den angegebenen Merkmalen erzielt man auf einfa­ che Weise eine sichere Abdichtung der geschlossenen Dros­ selklappe.The seal is particularly secure if according to claim 2 grooves are provided for receiving the sealing profile. Claim 3 finally describes a simple shape device formed as a throttle valve nes. With the specified characteristics one achieves on simp che secure sealing of the closed throttles selflap.

Anhand eines bevorzugten Ausführungsbeispiels wird die Erfindung im folgenden näher erläutert. Es zeigtUsing a preferred embodiment, the Invention explained in more detail below. It shows

Fig. 2 den Schnitt A-A durch das Gehäuse des Ver­ schlußorganes aus Fig. 1. Fig. 2 shows the section AA through the housing of the circuit Ver organes in FIG. 1.

Der dargestellte Luftsammler 1 weist u. a. eine Luftein­ trittseintrittsöffnung 2 sowie mehrere Luftaustrittsöff­ nungen 3, die zu den Ansaugkanälen der einzelnen Zylinder einer Brennkraftmaschine führen, auf. Der Innenraum des Sammlers 1 wird durch eine lediglich in einer Ausbrechung dargestellen Trennwand 4 unterteilt, wobei beidseitig der Trennwand 4 vorzugsweise die gleiche Anzahl von Luftaus­ trittsöffnungen 3 vorgesehen sind. Zur Beeinflussung der Resonanzcharakteristik des Luftsammlers weist die Trenn­ wand 4 eine Durchtrittsöffnung auf, die von einem als Drosselklappe 5 ausgebildeten Verschlußorgan verschließ­ bar ist.The air collector 1 shown has, inter alia, an air inlet opening 2 and a plurality of air outlet openings 3 , which lead to the intake ducts of the individual cylinders of an internal combustion engine. The interior of the collector 1 is subdivided by a partition wall 4 which is only shown in an outbreak, the partition wall 4 preferably having the same number of air outlet openings 3 on both sides of the partition wall. To influence the resonance characteristics of the air collector, the partition wall 4 has a passage opening, which can be closed by a closure member designed as a throttle valve 5 .

Die Drosselklappe 5 ist mit ihrer Welle 6 gemäß Pfeil­ richtung 14 drehbar in einem Gehäuse 7 gelagert. Dieses Gehäuse 7 kann von außen im Bereich der Durchtrittsöff­ nung in den Luftsammler 1 eingesetzt werden. Die Verbin­ dung erfolgt auf lösbare Weise durch mehrere Schrauben 8.The throttle valve 5 is rotatably mounted with its shaft 6 in the direction of arrow 14 in a housing 7 . This housing 7 can be used from the outside in the area of the passage opening in the air collector 1 . The connec tion takes place in a detachable manner by several screws 8

Um bei geschlossener Drosselklappe 5 eine sichere Tren­ nung der beiden durch die Trennwand 4 definierten Samm­ ler-Innenräume zu gewährleisten, ist das Gehäuse 7 gegen­ über der Trennwand 4 mit einer Dichtung 9 abgedichtet. Diese Dichtung 9 ist als eigenständiges Dichtprofil aus­ gebildet und ist in Nuten 10 im Gehäuse 7 bzw. in der Trennwand 4 geführt.In order to ensure safe separation of the two defined by the partition 4 collector ler interiors when the throttle valve 5 is closed, the housing 7 is sealed against the partition 4 with a seal 9 . This seal 9 is formed as an independent sealing profile and is guided in grooves 10 in the housing 7 or in the partition 4 .

Fig. 2 zeigt die Ausbildung der Drosselklappe 5 im De­ tail. Wie ersichtlich liegt die Drosselklappe 5 im ge­ schlossenen Zustand unter Zwischenschaltung einer Dich­ tung 11 an Vorsprüngen 12 der Wand des Gehäuses 7 an. Diese Gestaltung zeichnet sich gegenüber den üblichen Drosselklappen, die auch zur Leistungsregelung einer quantitativ gesteuerten Brennkraftmaschinen herangezogen werden, durch höchste Einfachheit aus. Dennoch ist die Wirksamkeit vollständig gewährleistet. Analog dem Dicht­ profil 9 ist auch das Dichtprofil 12 in Nuten 13 in den Vorsprüngen 12 geführt. Selbstverständlich kann das Dichtprofil 12 alternativ an der Drosselklappe 5 befe­ stigt sein. Gezeigt ist insgesamt ein Resonanz-Luftsamm­ ler, der sich bei optimaler Funktion durch einfachste Ge­ staltung auszeichnet. Fig. 2 shows the formation of the throttle valve 5 in De tail. As can be seen, the throttle valve 5 is in the closed state with the interposition of a device 11 on projections 12 of the wall of the housing 7 . This design is characterized by the highest simplicity compared to the usual throttle valves, which are also used to control the output of a quantitatively controlled internal combustion engine. Nevertheless, the effectiveness is fully guaranteed. Analog the sealing profile 9 and the sealing profile 12 is guided in grooves 13 in the projections 12th Of course, the sealing profile 12 can alternatively be BEFE Stigt on the throttle valve 5 . Overall, a resonance air collector is shown, which is characterized by simple design with optimum function.
