Abstract: In an automobile air flow system, air is forced through an air outlet element or nozzle (13, 21, 24) in a sweeping air stream pattern by an oscillating reed or vane member (42) supported solely at the downstream end (43) for air initiated oscillatory movement in the flow path of the air from the source; a weight (41) is on the free, upstream end of the vane and is of a size such that the rate of oscillation is determined by the spring constant of a spring in the vane member and the weight. The oscillating vane (42) is proportioned with respect to the cross-sectional size of the outlet such that at any extreme of its oscillatory movement it does not physically contact any other structural member.
