Abstract
A movement damping apparatus has a flow path through which a magnetorheological fluid is pressed. A device that generates a variable magnetic field has a core around which a coil is wound as well as pole surfaces in the flow path. The magnetic field acts on the magnetorheological fluid by way of the pole surfaces. The coil is arranged within the flow path along with the core, the axis of the coil extending perpendicular to the direction of flow of the magnetorheological fluid. The flow path has a jacket made of a magnetically conducting material.
