Abstract: An improved magnetorheological fluid damper is provided which effectively provides a smooth transition, without a sharp break in the damper force/velocity curve, between very low damping forces near zero damper velocity to higher damping forces at higher piston velocities while maintaining desirable maximum force levels. The damper includes a piston assembly, including a magnet assembly and a flow gap extending through the piston assembly to permit fluid flow between the chambers. The force/velocity optimization feature includes at least one groove open to the flow gap, formed in a non-magnetic portion of the piston and positioned in series with a part of the flow gap in a magnetic circuit generated by the magnet assembly and dimensioned/sized to permit fluid flowing the passage to experience a magnetorheological effect less than a magnetorheological effect experienced by fluid flowing through the flow gap but not through the groove.

Abstract: The invention provides a magnetorheological piston and damper assembly. The piston includes a piston body including at least one bypass port and an annular gap formed therein. The bypass port is in fluid communication with the annular gap. The bypass port includes a longitudinal portion extending substantially parallel to a piston longitudinal axis, and a bend portion extending substantially away from the longitudinal axis. The annular gap is spaced apart from the longitudinal portion and extends substantially parallel to the piston longitudinal axis. During operation, fluid flows through the bypass port and annular gap. The damper assembly includes a rod and a housing including the fluid carried therein. The piston is slidably carried in the housing and operably attached to the rod.

Abstract: A vehicle suspension damper assembly is provided which includes a cup member with a threaded opening formed therein. A piston rod includes a threaded portion, which is engaged in the threaded opening. An electrical connector including a terminal portion is received in an opening formed in the piston rod. The threaded engagement between the piston rod and the cup member is a predetermined length that reduces deflection of the cup member to reduce transfer of load to the terminal portion of the electrical connector.
