Abstract
A magnetorheological damper includes a cylinder and a magnetorheological piston. The magnetorheological piston is located within and slideably engages the cylinder. The magnetorheological piston includes a magnetically energizable passageway and a magnetically non-energizable passageway spaced apart from the magnetically energizable passageway. The magnetorheological piston also includes a pressure and flow control valve disposed to allow pressure-dependent fluid flow in the magnetically non-energizable passageway when the magnetorheological piston slides towards the first end of the cylinder.
