ABSTRACT:
An air diffuser includes first and second walls disposed in spaced side-by-side relationship and cooperating to define a passage for the flow of air in one direction between said walls. A pair of flanges extend towards each other from the downstream edges of the walls and defining an elongated outlet slot narrower than the width of said passage. A deflector vane is narrower than the passage and is disposed in the passage in a plane spaced upstream from the slot and generally parallel to said flanges. The deflector vane includes an inverted U-shaped central channel and flanges extending away from each other from the down stream ends of the U-shaped chanel and arranged generally parallel to the flanges defining the slot. The opposite ends of the vane are engaged in a U-shaped support with a spring engaging one wall of the U-shaped support and biasing the vane flanges into sliding engagement with the other wall. The vane thus being supported for back and forth edgewise movement in the plane to a first position in which the vane is closely adjacent to the first wall and spaced from the second wall, a second position in which the vane is closely adjacent the second wall, or selective positions between the two extremes.
