Abstract
A valve device is formed with a through-channel and a field generating device. A fluid which can be influenced by a field is provided in the through-channel and the field generating device is configured to act on the field-influenced fluid in the through-channel by way of a field. At least one adjustment device is provided with which the field that is active in the through-channel can be adjusted. A portion of the cross-sectional area of the through-channel can be adjusted, the portion being exposed to a field of a specific intensity so that the through-channel can also only partly be exposed to a field of a specific intensity. Thus, the through-channel, as seen in the direction of the flow, can be divided into regions of different flow resistance, whereby characteristic curves, which were previously attained only with difficulty, are easily obtained when using the valve device in a damper, for example.
