ABSTRACT:
An electro-rheological valve controller. The invention comprises a generally cylindrical casing holding an electro-rheological fluid; a reciprocating tappet attached at one end of the cylindrical casing, said tappet contacting cam means for thrusting said tappet into said casing toward a reciprocating valve lift member; a plunger member coupled to said tappet, said plunger being perforated to permit the flow of electro-rheological fluid therethrough; a reciprocating valve lift member situated within said casing and separated from said perforated plunger member by a biasing spring and said electro-rheological fluid, said lift member communicating with a valve to be lifted; 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 reciprocating lift member thereby lifting said valve to be lifted. In an alternative embodiment, the unique electrode configurations of the present invention are utilized in a valve controller with a by-pass conduit.
