Filter device, in particular gas filter

A filter device comprising:

• a housing component comprising:
• a receiving groove having opposed sidewalls, the receiving groove having
• a support rib formed as a projection in a base of the receiving groove and projecting between the opposed sidewalls;
• an annular filter element, comprising:
• an annular filter medium body surrounding a longitudinal axis, the annular filter medium body configured to be flowed through in a radial direction by a fluid to be cleaned relative to the longitudinal axis,
• wherein an axial, as used herein, refers to a direction of the longitudinal axis,
• wherein a radial, as used herein, as a direction traverse to the longitudinal axis;
• a central tube which is annular and elongated axially, the central tube formed as a grid structure and arranged in a radial interior of the annular filter medium body, an axial end of the axially elongated central tube is folded radially outwardly and projecting radially outwardly at and arranged on an axial end face of the filter medium body, forming a circumferentially extending support collar which projects radially outwardly from the axial end of the axially elongated central tube and extends at least partially across the axial end face of the filter medium body;
• wherein the circumferentially extending support collar has a plurality of through openings which open towards the axial end face of the filter medium body;
• at least one sealing element arranged on and protruding axially outwardly from the circumferentially extending support collar of the axially elongated central tube, the at least one sealing element configured to engage with and seal to the receiving groove of the housing component of a filter housing configured to receive the annular filter element, the at least one sealing element including:
• a first annular sealing projection, projecting axially outwardly away from the circumferentially extending support collar;
• a second annular sealing projection, projecting axially outwardly away from the circumferentially extending support collar and spaced radially inwardly away from the first annular sealing projection;
• wherein the spacing between the annular sealing projections forms an annular slit;
• wherein the annular sealing projections each have a first support surface at a first side facing the annular slit and a second support surface at a second side facing away from the annular slit;
• wherein the support rib engages into the annular slit between the annular sealing projections of the at least one sealing element;
• wherein the opposed sidewalls of the receiving groove contact against the second support surface of the annular sealing projections;
• wherein the opposed sidewalls of the receiving groove are supported against the second support surface of the annular sealing projections in the radial direction;
• wherein the support rib is supported against the first support surface of the annular sealing projections.
