Abstract: A flap bearing system for a flap shaft in a motor vehicle includes a first radial bearing within which is arranged a flap shaft comprising a flap shaft end. A ratable flap body is arranged on the flap shaft. A flow cross-section of a channel housing is controllable by rotating the flap shaft with the flap body. A first bearing housing surrounds the first radial bearing. A bearing housing cover comprises an opening through which the flap shaft end protrudes. The bearing housing cover closes the first bearing housing. A sleeve radially surrounds a section of the first bearing housing. A circumferential groove is formed at an outer circumference at the section of the first bearing housing surrounded by the sleeve. The flap shaft end protruding from the first bearing housing is arranged geodetically so as to be at a same height or above an opposite flap shaft end.

Abstract: A flap device for an internal combustion engine includes a flow housing comprising a flow channel, an actuating shaft, a flap body arranged on the actuating shaft in the flow channel, a housing bore arranged in the flow housing, a lever fixed on the actuating shaft, a bearing bush arranged in the housing bore, and a sealing disk comprising a surface which is at least partially spherically shaped. The housing bore has the actuating shaft protrude outwards therethrough. The lever comprises a rear wall. The bearing bush has the actuating shaft mounted therein.

Abstract: A valve device for controlling an exhaust gas flow of an internal combustion engine includes a housing comprising a channel which has the exhaust gas flow therethrough. A shaft is disposed in the housing. The shaft is rotatably mounted about a shaft axis. A flap is connected to the shaft. The flap controls a flow cross section of the channel. The flap comprises two flexurally rigid support plates. The support plates each comprise an outer periphery. An elastic flap body is arranged between the support plates. The elastic flap body comprises an outer periphery which is larger on all sides than the outer periphery of the support plates. A distance between the outer periphery of the elastic flap body and the outer periphery of the support plates is largest in an area of the shaft axis, and smallest at an angle of 90° relative to the shaft axis.
