  • Magnetorheological fluid device
    Publication number: 20020179145
    Abstract: The disclosure describes a magnetorheological fluid control valve. The magnetorheological fluid control valve comprises an electromagnetic coil having a first end and a second end. A first arm is magnetically coupled to the first end of the electromagnetic coil. A second arm is magnetically coupled to the second end of the electromagnetic coil. The second arm has a passage. A ferromagnetic rod having a diameter less than that of the passage is disposed in the passage and magnetically coupled to the first and second arms. A first manifold is coupled to the second arm at one end of the passage. A second manifold is coupled between the second arm and the first arm at an end of the passage opposite the first manifold. A magnetorheological fluid is disposed in the passage.
