Abstract:
A magnetorheological piston comprising a magnetorheological piston body having an electric coil, having a substantially magnetically energizable magnetorheological-fluid passageway adapted to be substantially magnetically energized by the electric coil and having a substantially magnetically non-energizable magnetorheological-fluid passageway spaced apart from the substantially magnetically energizable magnetorheological-fluid passageway, wherein the substantially magnetically non-energizable magnetorheological-fluid passageway has a valveless passageway throat and has a flow cross-sectional area which has a minimum at the passageway throat and which is larger away from the passageway throat, wherein the substantially magnetically non-energizable magnetorheological-fluid passageway is a valveless passageway, and wherein the substantially magnetically non-energizable magnetorheological-fluid passageway is bound on all sides by the magnetorheological piston body.
