ABSTRACT:
A motion-damping device (10) includes a piston (18) moveably disposed within a housing (16) and dividing the interior of the housing into an upper chamber (20) and a lower chamber (22). An electrorheological fluid which fills both chambers can pass from one chamber to the other chamber via at least one fluid passageway (28) formed in the piston. Each passageway, tapered to form a relatively narrow neck portion, is in close proximity to an electrode that receives an electric potential for developing an electric field within the passageway to control the viscosity of fluid in the passageway.
