Publication number: 20190070549Abstract: 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.Type: ApplicationFiled: November 2, 2018Publication date: March 7, 2019Inventors: Torsten Fritzsching, Pedro Miguel Pereira Madeira, Nadine Donauer, Andreas Franz, Marcel Holzwarth, Manfred Winter, Martin Gruber, Joachim-Paul Krieger

Publication number: 20190070545Abstract: A filter device has an annular filter element with a filter medium body for radial fluid flow relative to a longitudinal axis. A sealing element arranged at an end face of the filter medium body seals relative to a housing component of a filter housing receiving the filter element. The sealing element has support walls delimiting a slit between them. The housing component has a receiving groove engaging across the sealing element and provided with opposed side walls. The housing component has a support rib projecting into slit. The support walls each have a first support surface at a side facing the slit and a second support surface at a side facing away from the slit. The side walls of the receiving groove are radially supported at the second support surfaces of the support walls. The support rib is supported radially at the first support surfaces of the support walls.Type: ApplicationFiled: November 1, 2018Publication date: March 7, 2019Inventors: Nadine Donauer, Pedro Miguel Pereira Madeira
