Abstract
Ansaugvorrichtung mit einem Kanal (1), der unmittelbar oder mittelbar mit einem Zylinder einer Brennkraftmaschine kommuniziert, wenn die Ansaugvorrichtung an der Brennkraftmaschine angeordnet ist, mit einer Klappe (5), die auf einer Welle (7) gelagert ist und in dem Kanal (1) so angeordnet ist, dass sie in einer vorgegebenen Stellung eine Tumble-Strömung oder Swirl-Strömung in dem Zylinder erzeugt, und die mindestens eine Ausnehmung (11 bis 16) aufweist, die sich von der Seite der Klappe, die der Hauptströmungsrichtung (9) in dem Kanal (1) zugewandt ist, hin zu der Seite erstreckt, die der Hauptströmungsrichtung (9) in dem Kanal (1) abgewandt ist, wobei die Ausnehmung während des Betriebs der Brennkraftmaschine in Hauptströmungsrichtung (9) von einem Gasmassenstrom durchströmt wird, wobei die Klappe (5) aus dem Kanal (1) in eine Ausbuchtung (10) einschwenkbar und aus dieser ausschwenkbar ist, so dass in einer eingeschwenkten Stellung der gesamte Querschnitt des Kanals (1) für den Gasmassenstrom freigegeben ist.Intake device with a channel (1) which communicates directly or indirectly with a cylinder of an internal combustion engine when the intake device is arranged on the internal combustion engine, with a flap (5) which is mounted on a shaft (7) and in the channel (1 ) is arranged in such a way that it generates a tumble flow or swirl flow in the cylinder in a predetermined position and has at least one recess (11 to 16) which extends from the side of the flap which is the main flow direction (9) facing in the channel (1) extends to the side facing away from the main flow direction (9) in the channel (1), the recess being flowed through by a gas mass flow during operation of the internal combustion engine in the main flow direction (9), wherein the flap (5) can be swiveled out of the channel (1) into a bulge (10) and swung out of it, so that in a swiveled-in position the entire cross section of the channel (1) for d en gas mass flow is released.

Aufgabe der Erfindung ist es, eine Ansaugvorrichtung zu schaffen, durch die geringe Abgasemissionen gewährleistet sind und die eine ungehinderte Strömung eines Gasmassenstroms ermöglicht.The object of the invention is a To create intake device through the low exhaust emissions guaranteed and are an unimpeded flow of a gas mass flow allows.
Die Aufgabe wird gelöst durch die Merkmale des unabhängigen Patentanspruchs. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.The task is solved by the characteristics of the independent Claim. Advantageous embodiments of the invention are in the subclaims characterized.
Der Erfindung liegt die Erkenntnis zugrunde, dass sich in dem Bereich stromabwärts der Klappe Kraftstoffansammlungen bilden können und dass dies in überraschender Weise durch Ausnehmungen einfach verhindert werden kann. Weiterhin ist es gemäß der Erfindung möglich, die Klappe aus dem Kanal zu schwenken.The invention is based on the knowledge underlying fuel accumulations in the area downstream of the flap can form and that this is surprising Way can be easily prevented by recesses. Farther it is according to the invention possible, to swing the flap out of the channel.
Ausführungsbeispiele der Erfindung sind anhand der schematischen Zeichnungen erläutert. Es zeigen:Embodiments of the invention are explained using the schematic drawings. Show it:
Elemente gleicher Konstruktion oder Funktion sind mit den gleichen Bezugszeichen gekennzeichnet.Elements of the same construction or Functions are identified by the same reference symbols.
