ABSTRACT:
A transducer with which mechanical rotary motion can be interconverted with the flow of an electro-rheological fluid. Two, electrically conductive, movable, conveying surfaces are partly disposed in parallel confrontation thereby defining a fluid transfer path. A fluid transfer port is located at each end of the fluid transfer path through which electro-rheological fluid can enter and leave the transducer. The conveying surfaces are electrically connected to a voltage source and movable by means of a rotor to which they are connected. On application of a voltage difference between the conveying surfaces the electro-rheological fluid gells after which rotation of the rotor will urge the fluid along the transfer path and vice-versa.
