Abstract (en)

[origin: EP0898085A2] The motor has a piston movable in a housing (1) with two working chambers, an inlet channel for the liquid from a higher pressure chamber, an outlet channel to a lower pressure chamber and electrorheological valves (1a,1b) with annular gaps (8) connecting the channels and chambers with electrodes for generating an electric field. The valves are formed by longitudinal bores (6) through the housing wall containing insulated elements (7) bounding annular gaps of constant width. The elements and housing are connected to high voltage and earth respectively.
