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.

Rotary damper

A molded piston includes a base plate, having a plurality of holes, and a polymeric material molded around the base plate and extending through the holes so as to form a mechanical bond between the base plate and the polymeric material. The molded piston preferably includes integral seals in its outer circumferential surface and integral standoffs on its end surfaces. In some preferred embodiments, the molded piston also includes a magnet which creates a magnetic field in the area of the piston.
