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.degree. and swayable through 60.degree.. 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.
