A pressure-operated linear actuator in which the working liquid is Electro-Rheological (ER) fluid in which there is a single flow path between an inlet and an outlet of an associated pump in which there are two or more pistons and fluid chambers delineated by these pistons, which fluid chambers are connected in series by stationary ER valves distinct from the pistons such that the pressure as determined by each of the ER valves is applied to one or more of the chamber(s), wherein one or both of the ER valves are divided into two or more sections in order to minimize the length, and maximize the cross-sectional area, of the inactive connecting passages. |
