Abstract
A valve flap device having at least one valve housing having a shaft comprising a bearing surface and a valve axis, the shaft being rotationally supported about the valve axis by means of the bearing surface in the valve housing. A bearing element having a sliding bearing surface, wherein the bearing surface of the shaft contacts the sliding bearing surface. A bearing housing provided on the valve housing, in which the bearing element is supported at least in the radial direction to the valve axis, wherein the bearing element has an outer surface contacting the bearing housing. The support of the shaft is intended to be sufficiently tightly sealed, even for gaseous media, while simultaneously ensuring precise and statically determinate support. To this end, the bearing element is designed as a separate component coupled to the bearing housing about the valve axis with respect to the circumferential direction, such that the relative position between the bearing element and the bearing housing does not change in the circumferential direction when the shaft is rotated.
