Abstract

Drosselklappenanordnung (1) für Brennkraftmaschinen mit einem Gehäuse (2), das einen Luftkanal (3) aufweist, in dem eine scheibenförmige Drosselklappe (4) schwenkbar auf einer Antriebswelle (7) gelagert ist, wobei die Drosselklappe (4) mindestens eine Bohrung (5) für ein Befestigungselement (6) und eine zumindest teilweise gerundete Mantelfläche (8) aufweist, wobei die Mantelfläche (8) zwei Teilflächen (11a und 11b) und zwei Übergangsflächen (12a und 12b) aufweist, wobei die Teilflächen (11a und 11b) punktsymmetrisch zur Drehachse (10) der Drosselklappe angeordnet sind und die Übergangsflächen (12a und 12b) im Bereich der Antriebswelle (7) angeordnet sind, wobei die Teilflächen (11a und 11b) zwei Randstücke (13 und 14) aufweisen, derart, dass das in Schließstellung der Drosselklappe (4) zur Luftkanalwand (9) gerichtete Randstück (13) abgerundet ist.

Figure 00000001
Throttle valve arrangement (1) for internal combustion engines with a housing (2) which has an air duct (3) in which a disk-shaped throttle valve (4) is pivotably mounted on a drive shaft (7), the throttle valve (4) having at least one bore (5 ) for a fastening element (6) and an at least partially rounded outer surface (8), the outer surface (8) having two partial surfaces (11a and 11b) and two transition surfaces (12a and 12b), the partial surfaces (11a and 11b) being point-symmetrical are arranged to the axis of rotation (10) of the throttle valve and the transition surfaces (12a and 12b) are arranged in the area of the drive shaft (7), the partial surfaces (11a and 11b) having two edge pieces (13 and 14), such that in the closed position the throttle valve (4) facing the air duct wall (9) is rounded off the edge piece (13).
