Abstract
A fluid oscillation damper is provided with an electromagnetically controlled valve for varying the damping force of the oscillation damper. The electromagnetically controlled valve is housed within a compartment confined by two housing parts. A first housing part is fastened to a container of the oscillation damper A second housing part is fastened to the first housing part. Both housing parts are nonreleasably interconnected. The electromagnetically controlled valve is actuated by an electromagnetic coil. The electromagnetic coil is provided with a ferromagnetic core. This ferromagnetic core is constituted by a plurality of components. These components are assembled so as to reduce the magnetic resistance for the magnetic flux.
