Abstract
A ceiling vent diffuses air from a heating or cooling system in a laminar flow into a room for optimum dispersion in the room. Inlet air strikes a hinged vane within the vent. The vane deflects the air in a narrowing air way along a continuous concave curvature and extending all the way to the outlet opening of the vent. The vane responds to the force of air flow to narrow or enlarge the air way and, thus, regulate the velocity of air exiting the vent. A curved air catch associated with the vane directs the outflow of air and also laterally disperses air within the vent. The vent maintains a relatively constant velocity and diffusion of air into a room despite variable flow rates from the source of air.
