Disclosed is a valve for a magnetorheological fluid, comprising at least one energized electromagnet coil which forms a magnetic circuit in a magnetically conducting body. In said valve, at least a section of the magnetic circuit is formed by a composite material that has a resistivity of more than 10-4 Ωm and a relative permeability, in relation to the permeability of a vacuum, of more than 500 - in the frequency range up to 10 kHz, - in a magnetic flux range of 100 to 400 mT, and - at temperatures of 0°C to 100°C. |
