  • Magnetorheological valve and devices incorporating magnetorheological elements
    Patent number: 5452745
    Abstract: A valve used to control the flow of a magnetorheological fluid, in which the mechanical properties of the magnetorheological fluid are varied by applying a magnetic field, is described. The valve can comprise a magnetoconducting body with a magnetic core that houses an induction coil winding, and an hydraulic channel located between the outside of the core and the inside of the body connected to a fluid inlet port and an outlet port, in which magnetorheological fluid flows from the inlet port through the hydraulic line to the outlet port. Devices employing magnetorheological valves are also described.
    Type: Grant
    Filed: July 8, 1994
    Date of Patent: September 26, 1995
    Assignee: Byelocorp Scientific, Inc.
    Inventors: William I. Kordonsky, Sergei R. Gorodkin, Alexander V. Kolomentsev, Vladimir A. Kuzmin, Alexander V. Luk'ianovich, Nikolay A. Protasevich, Igor V. Prokhorov, Zinovii P. Shulman
