Abstract (en)
[origin: EP2141424A2] The invention relates to a ventilation device (1) for the natural supply of air or discharge of air, comprising an air flow channel (4) wherein a first, a second and a third regulating valve (5), (6), (7) are arranged so as to be able to rotate or hinge in series, so that during rotating or hinging of these regulating valves (5), (6), (7) the flow rate of air through this air flow channel (4) is regulated, at least two regulating valves (5), (6), (7) being mutually mechanically coupled. A ventilation device (1) of this type has high thermal resistance, a high temperature factor and high airtightness, so that said ventilation device is suitable for placing in or on a window, door, roof surface or external wall of a passive house building or a building in regions having low outside temperature during the heating season.
