Abstract
A device is provided for the emergency operation of at least one closure element of a cooling air supply apparatus and a correspondingly implemented cooling air supply apparatus for an internal combustion engine of a motor vehicle, a closure element being mechanically operationally linked to an actuator. The closure element is situated so it is movable between a closed position, in which it essentially closes a ventilation opening, and an open position, in which it releases the ventilation opening for cooling air to flow through. The actuator automatically transfers the closure element into the open position if a predetermined temperature is exceeded.
