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.
