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.
