ABSTRACT:
An adjustable magneto-rheological fluid device includes a movable piston adjacent a first chamber containing a first hydraulic fluid for moving the piston. The first hydraulic fluid interacts with a flexible magneto-rheological compartment containing a magneto-rheological fluid that flows between a first magneto-rheological fluid chamber and a second magneto-rheological fluid chamber. By controlling the flow of the magneto-rheological fluid, the device controls the first hydraulic fluid in the first chamber to bias the piston in a first direction. Additionally, the magneto-rheological fluid device may include a second chamber, containing a second hydraulic fluid, spaced apart from the first chamber on the opposite side of the piston. The second hydraulic fluid interacts with the flexible magneto-rheological compartment allowing the device to control the second hydraulic fluid to bias the piston in a second direction opposite the first direction.
