A rotary damper assembly for controlling the flow of a fluid includes inner and outer hollow cylinders, each having one or more side wall apertures, the inner cylinder being nested within the outer cylinder in a manner to permit relative axial rotation of the cylinders about a common longitudinal axis, the inner cylinder receiving the fluid flow at an axial inlet, and the flow of fluid through the assembly being proportional to the degree of alignment of the cylinder apertures.
