Abstract: A ring filter element, e.g., for a liquid filter device, is disclosed. The ring filter element includes an upper end disc, a lower end disc, and a filter material arranged in between the upper end disc and the lower end disc. A pin eccentrically arranged on the lower end disc that projects in an axial direction is provided for closing off a drainage channel. At least one support contour is disposed on the lower end disc adjacently to the pin. The at least one support contour projects from the lower end disc in the axial direction for supporting on a filter housing.

Abstract: A filter device for filtering a fluid may include a flat filter element. The flat filer element may extend flat in a longitudinal direction and a transverse direction. The filter element may include at least one pleated filter medium through which a flow path of the fluid leads in a height direction. The at least one filter medium may include a top side and a bottom side facing away from the top side. At least one strainer may be arranged on the top side. The at least one strainer may extend flat parallel to the filter medium and may include a strainer material having multiple passages such that the flow path leads through the strainer in the height direction.
