Filter element for liquid filtration

A filter element for liquid filtration, the filter element comprising:

• a hollow-cylindrical filter medium body surrounding a longitudinal filter element axis;
• an end disk arranged on and covering an end face of the hollow-cylindrical filter medium body, the end disk comprising:
• a central cutout axially penetrating the end disk;
• an axially projecting annular sleeve formed on an axially outer face of the end disk and projecting axially outward away from the axially outer face of the end disk, the axially projecting annular sleeve surrounding the central cutout;
• a circumferential annular collar formed on a radially outer circumference of the end disk and projecting axially outwardly therefrom, the circumferential extending annular collar surrounding the axially projecting annular sleeve;
• an elongated outflow channel having a U-shaped cross section and formed on the axially outer face of the end disk and extending across the end disk,
• wherein the elongated outflow channel carries liquid to be filtered or filtered liquid;
• wherein the axially projecting annular sleeve interrupts a central portion of the elongated outflow channel, dividing the elongated outflow channel into two elongated outflow channel portions, each of which connect to the axially projecting annular sleeve and open into an interior of the axially projecting annular sleeve;
• wherein the elongated outflow channel portions each extend radially outwards from the axially projecting annular sleeve to a radially outer end positioned at the radially outer circumference of the end disk so as to open at a radially exterior side of the hollow cylindrical filter medium body to receive liquid therefrom;
• wherein the elongated outflow channel is configured to be controlled by a drainage device.
