Adjustable magneto-rheological fluid device

An adjustable suspension device comprising:

• a first cylinder;
• a first chamber positioned within said first cylinder;
• a second chamber positioned within said first cylinder spaced apart from said first chamber;
• a movable piston positioned within said first cylinder separating said first chamber and said second chamber;
• a second cylinder fluidly coupled to said first cylinder;
• a first hydraulic fluid chamber, contained within said second cylinder, fluidly coupled with said first chamber;
• a second hydraulic fluid chambers contained within said second cylinder, fluidly coupled with said second chamber;
• a flexible fluid compartment contained within said second cylinder;
• a first flexible chamber contained within said flexible fluid compartment;
• a second flexible chamber contained within said flexible fluid compartment in fluid communication with said first flexible chamber;
• a predetermined fluid contained within said first flexible chamber and Said second flexible chamber, wherein said predetermined fluid is a controllable fluid selected from the group consisting of a magneto-rheological fluid and an electro-rheological fluid;
• a first hydraulic fluid within said first chamber and said first hydraulic fluid chamber for biasing said piston in a first direction;
• a second hydraulic fluid within said second chamber and said second hydraulic fluid chamber for biasing said piston in a second direction;
• a valve between said first flexible fluid chamber and said second flexible fluid chamber, wherein said valve controls the flow of said predetermined fluid between said first flexible chamber and said second flexible chamber to control the movement of said piston through said first hydraulic fluid and said second hydraulic fluid;
• a first elastomeric diaphragm disposed within said second cylinder defining a wall of said first flexible chamber;
• and
• a second elastomeric diaphragm disposed within said second cylinder defining a wall of said second flexible chamber.
