Patent ID: 8418819

Claim:
A movement damping apparatus, comprising: an amount of a magnetorheological fluid to be forced through a flow path along a flow direction; a magnet device for producing a variable magnetic field acting on the magnetorheological fluid to control flow characteristics thereof; said magnet device including a core forming pole surfaces through which the magnetic field acts on the magnetorheological fluid and a coil wound around said core, said core and said coil being disposed in said flow path and said coil having an axis extending substantially orthogonally to the flow direction; at least one partition wall with additional pole surfaces disposed in said flow path in the vicinity of said core and said coil and dividing said flow path into at least two flow sections; and elements in the form of circle segments having curved surfaces resting on an inner wall of an outlet channel sheathing said flow path, said elements providing the two outermost pole surfaces.
