Abstract:
1. A device for a sealed connection of a first duct in a first component and a second duct in a second component, the first component and the second component are adjoining components of an internal combustion engine, wherein the second component includes a duct-side recess, the device comprising: a connecting pipe having a pipe portion inserted into the duct of the first component and an annular collar, wherein the annular collar is accommodated in the duct-side recess of the second component; a radially sealing first sealing ring disposed between the pipe portion and a duct wall of the duct of the first component; an axially sealing second sealing ring disposed between an axially-facing face-side portion of the annular collar and a wall region of the duct-side recess such that the second sealing ring is preloaded with an axially oriented seal pressure, wherein the annular collar is accommodated in the duct-side recess with a radial circumferential gap, whereby tolerance corrections are allowed for compensating manufacturing tolerances without impairing a sealing action of the axially sealing second sealing ring.
