Ventilation attachment with movable cover

The present hiring relates to a ventilation attachment, in particular for ventilation devices * which, through the action of the natural wind, induce suction in a demarcated house corresponding opening position, the venting can be regulated. A suitable suction channel has been provided for these facilities, so that maximum use is made of excess pressure and excess pressure. The opening cuts are also made by the natural; The wind flows directly against it and the suction takes place on the principle of injection, which is why the vortex is very much dependent on the location and degree of direction
