Volume flow limitations for forced ventilated windows are either relatively complex or can only be used for medium-type sealing systems or only for stop-sealing systems. The invention relates to a closing device for limiting the volume flow, said device being arranged in the folding area of a window, comprising a base part and a sealing part. The sealing part is moveably arranged in relation to the base part. The closing device is firmly connected to the blend frame profile section by means of the base part in the folding area. The sealing part is distanced from the stop surface of the ledge of the casement, whereby air can flow freely between the folding area and the inside area when there is only a slight difference in pressure between the folding area and the inside area. When a minimum pressure difference between the folding area and the inside area is exceeded, the sealing part of the closing device is at least partially disposed in an adjacent position with respect to the stop surface and/or the inner seal of the stop. The inventive closing device is used in windows with forced ventilation. |
