Patent ID: 8302327

Claim:
A valve for a magnetorheological fluid, comprising: a duct formed in the valve for conducting the fluid through the valve; a coil disposed to have a current pass therethrough and to influence a viscosity or to cause a change in a flow resistance of the fluid in dependence on the current in said coil and to selectively open and close said duct, said coil having a radially outer circumference, an end-face region, an inner space, and an axial center line; a permanent magnet disposed in said inner space of said coil; said duct being formed partially in said end-face region of said coil and partially extending over said radially outer circumference of said coil as an annular duct; said duct being formed in said end-face region of said coil as a disk-shaped control duct configured to conduct the fluid radially with respect to said axial center line of said coil; and a housing with two halves enabling a flow cross section of said control duct to be continuously variable.
