Abstract

Die Erfindung bezieht sich auf eine Steuereinrichtung mit einer Steuerklappe (11) zur Steuerung eines Mediums innerhalb eines Stutzens (12), insbesondere auf eine Abgassteuereinrichtung mit einer Abgassteuerklappe, bei der die Steuerklappe (11) an einer Klappenwelle (13) gehalten ist, die mit ihren Enden (14, 15) in Lageraufnahmen (17, 18) der Wandung (16) des Stutzens (12) schwenkbar gelagert ist. Bei der Lagerung zumindest eines Endes (14) der Klappenwelle (13) liegt zwischen diesem Ende (14) und der Lageraufnahme (17) zumindest im wesentlichen nur eine kreisringförmige Linienberührung (21) vor, wodurch Ablagerungen von im Medium mitgeführten Partikeln, die sonst die Schwenklagerung schwergängig machen oder gar blockieren, vermieden sind.

Figure 00000001
The invention relates to a control device with a control flap (11) for controlling a medium within a connecting piece (12), in particular to an exhaust gas control device with an exhaust gas control flap, in which the control flap (11) is held on a flap shaft (13) which is connected to its ends (14, 15) in bearing receptacles (17, 18) of the wall (16) of the nozzle (12) is pivotally mounted. When storing at least one end (14) of the flap shaft (13) there is at least essentially only an annular line contact (21) between this end (14) and the bearing receptacle (17), as a result of which deposits of particles carried in the medium, which otherwise the Make swivel bearings stiff or even blocked, are avoided.
