  • Patent number: 10704843
    Abstract: A coolant connection of a heat exchanger includes at least one male connector on the side of the heat exchanger and at least one connection stem on the side of the housing. The at least one connection stem is designed on its side fluidically away from the heat exchanger for the connection of a coolant line or as part of a coolant line and on its side toward the heat exchanger as a female connector for the at least one male connector. The coolant connection provides at least two circumferential sealing areas. The coolant connector has a connecting flange enclosing radial fluid lines arranged between the sealing areas which vent to the environment. In the event of a seal failure, coolant leakage may pass through the radial fluid lines to the environment, preventing coolant from bypassing the sealing areas into and air intake tract.

  • Patent number: 10688427
    Abstract: 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.
