Adjustable valve with a transition region

A valve device, comprising:

• a valve formed with a through-channel and a magnetic field generating device;
• a magneto-rheological fluid to be conducted along a flow direction and to be influenced by a magnetic field in said through-channel, said field generating device being configured to act on said fluid by way of a magnetic field in said through-channel;
• and
• at least one adjusting device configured to adjust the magnetic field that is effective in said through-channel;
• wherein said through-channel and said field generating device are configured to adjust the magnetic field in said through channel with a virtual division, transversely with respect to a direction of flow, into a plurality of zones with respectively different magnetic field intensities, the zones including:
• a transmission section with lesser field intensity;
• a blocking section with higher field intensity;
• and
• a transition region connecting said transmission section and said blocking section with a field that is non-homogeneous transversely with respect to a channel cross section;
• and
• wherein said plurality of zones are contiguous within said through channel and without a separation by mechanical boundaries, and wherein the magnetic field in said transition region from a weakest to a strongest magnetic field, is a modifiable portion;
• and
• wherein said at least one adjusting device is configured to adjust and modify the transition region by varying the magnetic field that is effective in said through-channel.
