The invention relates to an electrical ventilation device that allows a driver to open and close the ventilation openings in a motor hood in an electric and fully controlled manner, for example to close the ventilation openings when the vehicle is being washed, in the event of rain or when the vehicle is stopped, so as to prevent water, dirt and other dust from penetrating beneath the hood, and to open the ventilation openings when the vehicle is started so as to cool the vehicle in the event of intense heat, using welded ventilation louvres that are connected to a welded shaft at the ends thereof. The base of the aforementioned shaft is mounted in a dynamo that lifts the shaft in order to open the louvres and lowers the shaft in order to close the louvers, in an electric and fully controlled manner, using controls located in the passenger compartment of the vehicle. A ventilation grille (2) is fitted in the motor hood (2), enclosing the electrical ventilation louvres (4) that are secured to the shaft (5) mounted in the dynamo, and an electric wire (7) connects the dynamo (6) to the controls (10) and, in turn, the controls to the group of electric wires connected to the key of the vehicle (11). |
