| 摘要 |
<p>The invention relates to a device for regulating the air flow rate in a ventilation device (1), comprising an independently operating valve (3) which is provided in an air passage duct (2) of the ventilation device (1) and which automatically adjusts the air passage opening as a function of the pressure difference between the inlet (4) and the outlet (5) of the air passage duct (2), the flap (3) is deformable at a first deformation point (7) up to a maximum deformation when the pressure difference increases, wherein, after deformation at the first deformation point (7), the flap (3) is further deformable up to a maximum deformation at a second deformation point (8).</p> |
