Abstract (en)
The present invention relates to a ventilation device (1), comprising an air flow passage (2) and a self-regulating valve (5) which is arranged in the air flow passage (2) so as to be tiltable and comprises a control limb (7) and a return limb (8) which are arranged on either side of the tilting point (6) at an angle with respect to each other and which are impingeable by the air flow in such a way that, at negative pressure at the outlet (4) with respect to the inlet (3) at increasing pressure difference between the inlet (3) and the outlet (4), said self-regulating valve (5) moves in a first direction of rotation (R) in order to restrict the air flow opening by means of the control limb (7) and, at positive pressure at the outlet (4) with respect to the inlet (3) at increasing pressure difference, moves in a second direction of rotation (S) in order to restrict the air flow opening by means of the return limb (8).
