Abstract
A ring filter element is provided for a liquid filter, especially for an oil filter for purifying lubricating oil, especially for an internal combustion engine of a motor vehicle. The ring filter element comprises a filter material which is arranged in an annular manner and at least one end disk comprising an outwardly protruding journal which is eccentrically arranged in relation to the longitudinal central axis of the ring filter element. The functionality of the ring filter element can be improved by providing a discharge channel which radially penetrates the journal and the associated end disk next to the filter material.
