Patent number: 10688427Abstract: A filter element has a filter bellows with circumferential seal having a seal region and a fastening region with radial and axial fastening sections. The radial fastening section has a holding surface facing away from the filter bellows and engaging a radially inner pressure-exerting section of a housing. The axial fastening section provides a radially inner boundary of a circumferential groove of the seal region that receives a radially outer pressure-exerting section of the housing. A seal projection forms a radially outer boundary of the groove. The seal region has an axially acting sealing surface opposite the groove axially spaced farther from an axial filter bellows end face than the holding surface. Axial spacing between groove base and axially acting sealing surface is greater than a spacing between a transition of the groove base into the axial fastening section and a transition of the holding surface into the seal region.Type: GrantFiled: December 2, 2018Date of Patent: June 23, 2020Assignee: MANN+HUMMEL GmbHInventors: Timo Dirnberger, Daniel Schmid, Bernd Joos
