Patent ID: 8523973

Claim:
A filter element ( 1 ) for fluid filtration of intake air of an internal combustion engines, comprising a hollow-cylindrical star shape-folded filter medium ( 2 ) having a center axis; an outlet-side end disk ( 3 ) arranged at an outlet side end face of the filter medium ( 2 ); a second end disk ( 4 ) arranged at an axially opposing end face of the filter medium ( 2 ); a hollow-cylindrical support lattice ( 5 ) which is arranged in the interior ( 6 ) of the filter medium, the hollow-cylindrical support lattice extending from the outlet-side end disk to the second end disk through the interior of the filter medium; wherein the support lattice at the outlet-side end of the filter element has a connecting area ( 11 ) including a coupling element ( 7 ) for coupling the filter element to an outlet socket of a filter housing; wherein the support lattice ( 5 ) in the connecting area ( 7 ) has a collar ( 8 ) at a radial exterior of a main part the hollow cylindrical support lattice, the collar ( 8 ) including: a first collar section having a first end secured to the exterior of the main part of the hollow cylindrical support lattice and extending in direction of the center axis axially to a second end; a second collar section joined to an opposing axial end of the first collar section, the second collar section projecting in radial direction outwardly and partially projects past the outlet-side end face ( 9 ) of the filter medium; wherein the outlet-side end disk ( 3 ) encloses the outlet-side end face ( 9 ) of the filter medium ( 2 ) and the collar ( 8 ) and has an annular axially projecting seal ( 10 ) configured to seal axially by axial compression within the filter housing; wherein the second collar section is spaced apart from the outlet side end face of the filter medium; wherein material of outlet-side end disk is not connected with the main part of the support lattice or the connecting area.
