Filter Element with Venting Function for Suspension on a Filter Head, and a Filter System

A filter element for a fluid to be filtered, the filter element configured to be suspended from a filter head, the filter element comprising:

• an annular filter medium, surrounding a longitudinal axis extending through an open interior of the annular filter medium;
• an end disk fixed onto an covering a first axial end of the annular filter medium, the end disk having a central opening, the end disk forming a first U-shaped annular socket having:
• an annular second wall section formed as an axially outwardly projecting annular wall on the end disk, the annular second wall section surrounding the central opening of the end disk and projecting axially outwardly away from the annular filter medium;
• and
• a first annular wall section formed as an axially projecting annular wall arranged in an interior of the annular second wall section and surrounding the central opening of the end disk,
• wherein an axially outer portion of the annular second wall section is joined to an axially outer portion of the first annular wall section by a back section of the end disk, such the first U-shaped annular socket opens in a direction towards the annular filter medium;
• a central tube arranged in the interior of the annular filter medium, the central tube forming a second U-shaped annular socket having:
• an annular end section formed at an axial end if the central tube, projecting into and engaging into the first U-shaped annular socket of the end disk;
• and
• an angled rim section formed at the axial end if the central tube and projecting axially outwardly to contact against a radially inner side of the first annular wall section of the end disk;
• a venting channel configured to vent a clean side and/or a raw side of the filter element,
• wherein the venting channel coaxially surrounds the fluid outlet channel in the radial direction and extends at least in sections thereof in an axial direction of the longitudinal axis,
• wherein the venting channel at an inlet side is connected by a first capillary channel with a raw side of the filter medium which is upstream of the filter medium relative to fluid flow,
• wherein the first capillary channel is arranged at a radially outer side of the venting channel and circumferentially surrounding the venting channel and the fluid outlet channel,
• wherein the raw side is arranged in a fluid flow direction upstream of the filter medium.
