Patent ID: 8899548

Claim:
A device, comprising: a valve device for a combustion engine, including: 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; and 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, wherein the valve device is configured such that the coupling connects the drive shaft and the valve shaft with one another such that the connection between the drive shaft and the valve shaft is released above a predetermined threshold torque, so that rotation of the valve shaft relative to the drive shaft is possible, wherein the valve shaft comprises a half-cylindrical projection in the area of its connection to the drive shaft and in that the drive shaft comprises a quarter-cylindrical projection in the area of its connection to the valve shaft, wherein the half-cylindrical projection and the quarter-cylindrical projection engage with each other so that the valve shaft can be rotated by 90° in relation to the drive shaft above the threshold torque.
