CLOSING APPARATUS AND AIRFLOW DEVICE

A closing apparatus for a fluid passage having a closing body arranged in the fluid passage. In order to simplify the regulated air supply in a motor vehicle, the closing body includes a definedly deformable base structure surrounded by a wrapper, which more or less closes the fluid passage as a function of the deformation of the base structure. The closing body closes the fluid passage when the base structure takes up a closed position with the wrapper. And, the closing body partially releases the fluid passage when the base structure with the wrapper takes up an opened position.
