Abstract

Adjustable dampers using electrorheological (ER) fluids comprise one or more annular ER fluid transfer ducts in fluid communication with fluid chambers on opposite sides of the damper pistons. Each duct has one or more contoured surfaces or bands along a portion of the length of one or both walls of the ducts providing one or more annular constricted working areas through which the ER fluid is forced when displaced by movement of the pistons. By selectively applying a voltage/electric field across the primary working areas, the flow resistance of the ER fluid passing through the primary working area is increased which increases the damping force of the dampers.
