    Abstract: An annular filter element has a filter medium body configured to be flowed through by a fluid to be purified in a radial direction. A sealing element is arranged at the end face of the filter medium body and extends circumferentially around the end face. The sealing element has at least one first sealing section comprising a massive and large cross-sectional area and one or more second sealing sections with a cross-sectional area that is at least partially reduced in comparison to the large cross-sectional area. The one or more second sealing sections include a second sealing section with a groove-type recess, wherein the groove-type recess extends at least approximately across a length of the second sealing section with the groove-type recess or across a portion of said length.

  • Patent number: 10744444
    Abstract: A filter element has a filter medium body enclosing an inwardly positioned flow space and having a center axis. A support frame is arranged at an inner side of the filter medium body. At least one circumferentially extending sealing ring lip is arranged at the filter medium body and projects axially in an axial direction relative to the center axis past an end face of the filter medium body. The sealing ring lip is designed to seal relative to a housing component of a receiving filter housing. A support ring is arranged at the end face of the filter medium body at a radial distance to the sealing ring lip in a radial direction relative to the center axis. The support ring is supported in the radial direction at the support frame and is formed as one piece together with the support frame.

  • Patent number: 9205358
    Abstract: A filter element has a filter body with a longitudinal axis, the filter body having a first end face and a second end face opposite the first end face. A first end plate is arranged at the first end face and has an open or closed configuration. A second end plate is arranged at the second end face. A support tube is arranged concentrically to the longitudinal axis and extends between the first and second end plates. The first end plate is reinforced by a reinforcement ring. The reinforcement ring has first openings that are visible from the exterior of the reinforcement ring, wherein the first openings enable a filling level check of a filling level of a material that connects the first end plate with the first end face.
