Air passage device for changing air flow in chamber i.e. engine compartment, of motor vehicle, has operating device including control device for controlling modifiable magnetic field of operating magnet arrangement
Air passage device for changing air flow in chamber i.e. engine compartment, of motor vehicle, has operating device including control device for controlling modifiable magnetic field of operating magnet arrangement
The device (10) has an operating device with an operating magnet i.e. electromagnets (18, 20), containing operating magnet arrangement with modifiable magnetic field, and a reaction body arrangement including reaction body i.e. permanent magnets (22, 24), to generate operating or retaining force. The operating magnet arrangement and the reaction body arrangement are connected with a base assembly (12) and a control assembly (13). The operating device has a control device for controlling the modifiable magnetic field of the operating magnet arrangement.
