Filter element and filter system

A filter system comprising:

• a filter housing comprising disturbance geometries and a seal surface;
• a filter element comprising:
• a filter medium;
• a first end disk connected to the filter medium and a second end disk connected to the filter medium, wherein the filter medium is arranged between the first end disk and the second end disk;
• wherein the first end disk comprises a positioning and sealing section facing away from the filter medium;
• wherein the positioning and sealing section comprises externally arranged positioning recesses engaging the disturbance geometries of the filter housing with form fit and positioning the filter element circumferentially in relation to the filter housing;
• wherein the positioning and sealing section further comprises an inner side and an interface arranged at the inner side, wherein the interface is configured to seal the filter element radially in relation to the filter housing and to position the filter element axially in relation to the filter housing;
• wherein the interface, viewed along a longitudinal direction of the filter element oriented from the first end disk toward the second end disk, extends farther into the positioning and sealing section than the externally arranged positioning recesses;
• wherein the seal surface of the filter housing, at least in sections, radially compresses the interface of the filter element, and wherein a respective end surface of the disturbance geometries of the filter housing, viewed along the longitudinal direction, is arranged behind the seal surface of the filter housing.

A filter element for a filter system, the filter element comprising:

• a filter medium;
• a first end disk connected to the filter medium and a second end disk connected to the filter medium, wherein the filter medium is arranged between the first end disk and the second end disk;
• wherein the first end disk comprises a positioning and sealing section facing away from the filter medium;
• wherein the positioning and sealing section comprises externally arranged positioning recesses configured to engage disturbance geometries of a filter housing of the filter system with form fit and to position the filter element circumferentially in relation to the filter housing;
• wherein the positioning and sealing section comprises an inner side and an interface arranged at the inner side, wherein the interface is configured to seal the filter element radially in relation to the filter housing and to position the filter element axially in relation to the filter housing;
• wherein the interface, viewed along a longitudinal direction of the filter element oriented from the first end disk toward the second end disk, extends farther into the positioning and sealing section than the externally arranged positioning recesses;
• wherein the interface comprises an annular seal groove surrounding circumferentially completely a symmetry axis of the filter element;
• wherein the annular seal groove is configured to engage a seal rib of the filter housing with form fit and to position the filter element axially in relation to the filter housing;
• wherein the interface comprises a circumferentially extending seal surface configured to seal the filter element radially in relation to the filter housing;
• wherein the annular seal groove, viewed along the longitudinal direction, is arranged behind the circumferentially extending seal surface;
• and
• wherein the externally arranged positioning recesses, viewed along the longitudinal direction, project farther into the positioning and sealing section than the circumferentially extending seal surface.
