Window or door ventilation element has base plate with displaceable sealing slider controlled by air flow passing air stream path

摘要

the ventilation element (4) has a base plate engaging in the area of the seal (16) between the casement overlap (25). A sealing slider is mounted adjustable on the base plate where it is influenced by the ventilation flow passing through the air stream path (6b). The vent, more particularly the base plate and sealing slider have at least in the area of the door width adjoining the seal such width and height that in the installed and useful position of the vent the window or door casement can be pivoted and/or tilted. the sealing slider is preferably plate-shaped and mounted to slide between the base plate and an upper guide plate (9). The upper guide plate does not project beyond the flange area of the window inside the window casement frame.
