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 and a hollow valve element rotatable between at least two rotational positions via a valve shaft supported rotatably in the housing, which valve element comprises at least two openings, which, depending on the rotational position of the valve element, can be connected with the fluid connections of the housing, further comprising an electromotive drive with a drive shaft for rotating the valve element, the drive shaft and the valve shaft being connected via a coupling with one another. According to the invention, the coupling connects the drive shaft and the valve shaft torque-proof with one another up to a predetermined threshold torque and releases the torque-proof connection between the drive shaft and the valve shaft above the predetermined threshold torque, so that rotation of the valve shaft relative to the drive shaft is possible.
