Device for the sealed connection of communicating ducts in adjoining and/or connected components of an internal combustion engine

摘要

A device for the sealed connection of communicating ducts in adjoining components or an internal combustion engine includes a connecting pipe inserted into the ducts and which has a pipe portion which projects into a first component. A sealing ring is disposed between the pipe portion and an associated duct wall of the first component. The connecting pipe furthermore has an annular collar accommodated in a duct-side recess of the second component, wherein an axially sealing second sealing ring is arranged between a face-side portion of the annular collar and a wall region of a duct-side recess, the annular collar accommodated in the recess with a radial circumferential gap.

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.
