Patent ID: 8778044

Claim:
A filter element for exchangeable use in a filter housing, comprising: a filter body ( 3 ) with a longitudinal axis ( 7 ) and an axial end face ( 12 ); a one-piece monolithic circumferentially extending seal ( 4 ) arranged in the area of an end face side ( 5 ) of the filter body ( 3 ), the seal ( 4 ) comprising a circumferential fastening section ( 24 ) secured directly onto an exterior side surface ( 11 ) of the filter body ( 3 ) and extending on the exterior side surface ( 11 ) to the end face ( 12 ); a transition section ( 13 ) with a first end secured to the fastening section ( 24 ) proximate to the end face ( 12 ), the transition section ( 13 ) extending in a direction of the longitudinal axis ( 7 ) from the end face ( 12 ) axially outwardly to a second end; wherein the transition section ( 13 ) tapers inwardly from the first end towards the longitudinal axis; a sealing section ( 8 ) arranged axially outwardly from and spaced away from the end face ( 12 ) of the filter body ( 3 ) in the direction of the longitudinal axis ( 7 ), the sealing section ( 8 ) integrally and monolithically formed with the fastening section ( 24 ), the sealing section ( 8 ) including a circumferential support wall ( 9 ) secured to the second end of the transition section and projecting in the direction of the longitudinal axis ( 7 ) outwardly from the filter body ( 3 ), the circumferential support wall ( 9 ) recessed radially inwardly toward the longitudinal axis relative to the circumferential fastening section ( 24 ); at least one sealing lip ( 17 ) integrally and monolithically formed on a radially outer surface of the circumferential support wall, the at least one sealing lip ( 17 ) extending radially outwardly from the support wall; wherein the circumferentially extending seal ( 4 ) including the circumferential fastening section, the transition section, the sealing section, the circumferential support wall and the at least one sealing lip are formed as a one-piece monolithic elastic component of rubber-elastic material; wherein the sealing section in a direction of width ( 10 ) is provided for a radial sealing contact on a housing wall ( 6 ) of the filter housing ( 2 ); wherein the monolithic rubber-elastic circumferentially extending seal along its portion positioned axially outwardly from the end face is self-supporting, and not arranged on a fastening means for support, the circumferentially extending seal open on its radially inward side to a free-flow cross section of the filter element end face.
