  • the present invention relates to a filter device, in particular for a motor vehicle.
  • the invention further relates to a filter element of such a filter device and a motor vehicle with such a filter device.
  • Filtering devices are often used as oil filters in motor vehicles, in which they have an oil-care function for the oil used, for example, in an internal combustion engine of the motor vehicle.
  • Such filter devices have, in a known manner, a ring filter element which, for example, flows through from the outside to the inside so that a spatial area within the ring filter element forms a clean side of the filter device and a spatial area arranged outside the ring filter element forms a raw side of the filter device.
  • a filter device usually has a filter housing, on which a housing cover can be fastened. The ring filter is then inserted into the housing cover attached to the filter housing, so that the ring filter separates the raw side from the clean side of the filter device in a state of the housing cover mounted in the filter housing.
  • the filter housing can now have a feed opening in fluid communication with the raw side and a discharge opening in fluid communication with the clean side.
  • the fluid to be filtered flows via the feed opening into the clean side of the filter device, then flows through the ring filter element from the raw side to the clean side of the filter device, and leaves the clean side again through the discharge opening.
