Abstract: A valve device for a combustion engine, comprising a housing with at least two fluid connections, a hollow valve element, being rotatably supported in the housing between at least two rotational positions, the valve element comprising at least two openings, which, dependent on the rotational position of the valve element can be connected with the fluid connections of the housing, and a drive for rotating the valve element. The valve element is connected torque proof with a shaft, the shaft being rotatably supported at two opposing bearings of the housing, and the shaft, at least at one end, being rotatably supported in a bearing bush, the bearing bush being received at one of the bearings torque proof against a rotation about the shaft axis, with the inner surface and/or the outer surface of the bearing bush being formed spherically.

Abstract: The invention relates to a valve device for a combustion engine, in particular of an automobile, comprising a housing with at least two fluid connections, a hollow valve element, being rotatably supported in the housing between at least two rotational positions, said valve element comprising at least two openings, which dependent on the rotational position of the valve element can be connected with the fluid connections of the housing, and a drive for rotating the valve element. According to the invention, the valve element is connected torque proof with a shaft, which shaft is rotatably supported at two opposing bearings of the housing, wherein the shaft is at least at one end rotatably supported in a bearing bush, which bearing bush is received at one of the bearings torque proof against a rotation about the shaft axis, wherein the inner surface and/or the outer surface of the bearing bush is formed spherically.
