Magneto-rheological fluid damper

摘要

A controllable magneto-rheological damper includes a housing; a piston movably disposed in the housing; a cavity defined by the housing and the piston; a passage fluidically coupled to the cavity; a magneto-rheological fluid contained within the cavity, wherein motion of the piston is damped by flow of the magneto-rheological fluid through the passage; and a magnet disposed to produce a magnetic field within the passage with field lines essentially parallel to the passage.
