Abstract: A magneto-rheological damping device comprises a core element for carrying a magnetic flux and a magnetic flux generator positioned adjacent to a portion of the core element and operable to generate a magnetic flux in the core element. A sleeve is positioned over the core element and magnetic flux generator and includes a plurality of protrusions extending generally radially outwardly from a center of the core element. A flux ring surrounds the core element and sleeve and defining a passage between flux ring and core element for the flow of a magneto-rheological fluid. The sleeve protrusions are configured to engage the flux ring and secure the flux ring in a concentric position around the core element and sleeve.
