Abstract

A louver vent is disclosed which has successive levels, in flow direction, of in each case one set of slats which are pivoted by means of a joint operating handle. In order to provide air deflection corresponding to the associated slat position, at least one single slat is positioned ahead of the row of slats first subjected to flow, which single slat is arranged close to a housing wall of the slat of one of the rows of slats which is in the same alignment close to the wall. The single slat is moved, during the shifting of the operating handle, into a selected end position against the pivoting direction of the actuated slats after passing over their central position, so that the air stream is directed away from the housing wall and in the direction of the associated, oppositely disposed slats.
