Abstract (en)

The present invention relates to a ventilation device, comprising a self-regulating valve (2), which is arranged in an air flow duct (1) so as to be tiltable between an open position and a closed position, in which said valve (2) is arranged on one or more supporting bodies (3) in the air flow duct (1) in such a manner that essentially a line contact (A) results between the valve (2) and the one or more supporting bodies (3), in which said ventilation device can be installed in roofs having different angles of inclination while retaining its self-regulating action, due to the fact that the centre of gravity (Z) of the valve (2) is situated next to the line contact (A) at each installation position and due to the fact that, in an installation position which is situated virtually in the middle between the outer installation positions, the centre of gravity (Z) of the valve (2) in the open position is situated in a virtually horizontal plane through the line contact (A) and the distance (X) between the line contact (A) and the centre of gravity (Z) is such that when the pressure difference across the valve (2) decreases, this valve (2) tilts to its open position.
