Abstract: A ventilating or air supply nozzle for panes, especially windshields, and at least one portion of the interior of a passenger vehicle or a driver's cab. The nozzle has an air inlet connection for fresh air and/or recirculated air, and an air outlet opening. The nozzle also includes a swivel damper which is pivotably mounted about an axis within a housing, and is provided with curved guide elements or deflectors. In order to be able to rapidly deice the windshield, the plane of the air outlet opening extends at an obtuse angle relative to the axis of the air inlet connection. The width of the free cross-sectional area of the air outlet opening is at least as great as the width of the cutting plane of the projection of the air inlet connection with the plane of the air outlet opening. A housing portion which is in the shape of a circular arc essentially covers the obtuse angle. The pivot axis of the swivel damper is disposed on that side disposed across from the housing portion.
