Device with a magnetorheological fluid (MRF)

摘要

A movement damping device in which a magnetorheological fluid for damping movement is forced through a constricting flow path, wherein at least one coil (3) and at least one core (4) are provided for generating a magnetic field, wherein the magnetic field in the region of the flow path acted on pole faces on the magnetorheological fluid, and wherein the pole faces (6, 7) are arcuate and thereby at least one between the pole faces (6, 7) lying, arcuate flow path (F) is formed, characterized in that the axis of the coil ( 3) is normal to the flow direction and the core (4) and the pole faces (6, 7) made of a ferromagnetic material.
