Abstract: In a movement damping apparatus, a magnetorheological fluid is pressed through a flow path. A device generating a variable magnetic field comprises a core around which a coil is wound as well as pole surfaces in the flow path, the magnetic field acting on the magnetorheological fluid by means of said 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.

Abstract: A valve is particularly suited for a movement damping apparatus. The valve has a field-generating device, such as a magnet unit, and a fluid that is subjected to the field, such as a magnetorheological fluid, is pressed through a flow path forming a bottleneck. At the bottleneck the fluid is subject to the field and it changes its flow characteristics in response to the field. The flow path is divided into at least two flow tracks by a partition that forms one or more additional friction surfaces.
