ABSTRACT:
An electro-rheological shock absorber. The invention comprises a generally cylindrical inner casing holding an electro-rheological fluid; a reciprocating arm means attached at one end of the cylindrical casing; a dampening plunger member coupled to said arm and extending into said electro-rheological fluid, said dampening plunger being perforated to permit the flow of electro-rheological fluid therethrough; and electrode means coupled to said perforated member for generating an electric field within said perforated member such that said electro-rheological fluid within said perforated member solidifies, whereby said plunger applies a compressive fluid force against said fluid so as to provide a dampening force. In an alternative embodiment, the unique electrode configuration of the present invention are utilized in a shock absorber having a by-pass conduit.
An alternative embodiment utilizes the conventional design of original shock absorbers and employs the shock absorber oil as the working fluid; the conventional flap valves, or other valves, are replaced by electrified self contained electro-rheological control valves, each containing the unique electrode configuration of the present invention, to control the oil flow through valves in the conventional dampening plunger and/or a similar valve located between the working chamber and a reserve/expansion chamber.
