Abstract
A novel air flow control valve for an air outlet in an HVAC housing provides for strong, even seal pressure all the way around the edge of the opening. In stead of a swinging door hinged at one edge of the opening, in which seal pressure is strong on the hinge edge but weaker on the opposite edge, a flat panel is moved straight toward and away from the opening. In the closed position, the sealing pressure is even all the way around. The sealing panel is moved back and forth by a rotary cam mechanism.
