Flat filter element of a filter, filter and support device of a filter

A filter (10) for fluids having a central axis, comprising:

• a flat filter element (34;
• 134;
• 234;
• 334) including
• a filter medium (64;
• 164;
• 264;
• 364) with an inflow-side raw side (62;
• 162;
• 262;
• 362′s)) at a first axial side of the filter element and an outflow-side clean side (58;
• 158;
• 258;
• 358) at an opposing axial side of the filter element;
• wherein the filter element is a flat filter element and not a round filter element, the filter medium of the flat filter element having plurality of lateral side faces forming a parallelpipedal filter element, each lateral side face extending axially from the inflow-side to the outflow-side, the lateral side faces;
• and
• an element sealing section (77;
• 177, 277;
• 377) arranged on the lateral side faces of the filter medium and circumferentially surrounding the filter medium, the element sealing section arranged at one of the:
• the raw side (62;
• 162;
• 262;
• 362), the clean side (58;
• 158;
• 258;
• 358) or arranged between the raw side (62;
• 162;
• 262;
• 362) and the clean side (58;
• 158;
• 258;
• 358);
• a sealing device (78;
• 178;
• 278;
• 280;
• 378) arranged on and supported on the element sealing section (77;
• 177, 277;
• 377);
• a filter housing in which the flat filter element (34;
• 134;
• 234;
• 334) is replaceably arranged;
• wherein the sealing device (78;
• 178;
• 278;
• 280;
• 378) is arranged on the filter medium and forms a seal between the filter element and the filter housing (12) sealing the raw side (62;
• 162;
• 262;
• 362) relative to the clean side (58;
• 158;
• 258;
• 358);
• at least one support/positioning body (72, 74, 76;
• 172, 174, 176;
• 276;
• 376) supported on an interior of the filter housing, the at least one support/positioning body (72, 74, 76;
• 172, 174, 176;
• 276;
• 376) positioning and securing the sealing device (78;
• 178;
• 280;
• 378) within the filter housing (12), on the one hand on the sealing device (78;
• 178;
• 280;
• 378) and on the other hand on the filter housing (12);
• wherein the at least one support/positioning body includes
• at least one L-shaped corner support leg having two angled leg portions forming an L-shaped support leg profile, the at least one corner support leg arranged on a corner of the filter medium formed where an adjacent two of the lateral side faces of the filter medium meet;
• wherein each of the two angled leg portions of at least one L-shaped support leg are arranged directly on a different one of the lateral side faces forming the corner;
• wherein the at least one L-shaped corner support leg has an first axial end projecting axially outwardly beyond the filter element at a nearest one of the inflow-side or outflow-side and resting on an interior of the housing;
• wherein an opposing second axial end of the at least one L-shaped support leg is embedded into the sealing device, securing the at least one L-shaped support leg to the filter medium.
