First Claim
1. An air outlet comprising a face plate having a first circular aperture defined therethrough and a plurality of shaft members extending orthogonally therefrom;
- a rear plate having a plurality of openings defined therethrough in registry with said shaft members for receiving said shaft members in registered passage therethrough to attach said rear plate to said face plate, said rear plate having a second circular aperture defined therethrough;
a plurality of shaft retainer means, each operatively securable about a different one of said shaft members to secure said rear plate to said face plate;
a valve member having a spherical body portion having a diameter larger than the diameter of either said first and said second circular aperture and operatively interposed between said face plate and said rear plate for engagement therewith and rotation relative thereto, said valve member having a cylindrical passageway defined centrally therethrough between a tapered entrance and an exit, said tapered entrance having a transverse area which is greater than the transverse area of said exit;
a torsion free centering assembly mounted within the centrally disposed cylindrical passageway of said valve member;
an axially extending damper actuator means mounted through said centering assembly and having an adjusting means at one end thereof and a flexible spring member at the other end thereof;
a dome-shaped damper circumscribed about said spring member and axially mobile in response to the rotation thereof; and
damper guide means extending through said damper into seated engagement upon said centering assembly for directing said damper between totally obstructive engagement within said nozzle entrance to a totally non-obstructive position relative to said central passageway as said damper migrates upon said spring member in response to the rotation of said adjusting means.

Abstract
An air outlet having a ball shaped valve member having a central passageway defined therefrom intermediated a convergent entrance and an exit, the transverse area of the entrance being at least 45% greater than the transverse area of the exit. The valve members is rotatable through 360° and swayable through 60°. A damper arrangement selectively actuable between a totally closed and a totally non-obstructive position relative to said passageway is described having damper actuator means and damper guide means coacting to effect a preselected location of said damper relative to said passageway in the valve member.
