Abstract
A rotary damper includes a housing and a vane. There is an indentation in the housing which permits fluid to flow readily from one side of the vane to the other during part of the rotary stroke. At the end of the rotary stroke, there is an alternative path for fluid to take from one side of the vane to the other, and this path preferably includes an adjustable aperture so the amount of damping at the end of the stroke can be adjusted.
