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.
