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.
Claims20
A valve, comprising:
- a valve body formed with at least one through-channel;
- a field producing device disposed to produce a field being effective in said through-channel;
- a fluid having a flow characteristic subject to the field in said through-channel;
- and
- at least one partition wall dividing said through-channel into a plurality of flow sections of said through-channel and forming additional surfaces of said through-channel;
- and
- wherein said field producing device is a magnet unit configured to generate a magnetic field with a magnetic field strength or a flux density being substantially identical in all of said flow sections.
