Exhaust duct system for internal combustion engines, has two exhaust gas guide portions that are relatively movable, where sealing element is provided with end sleeve with circumferential sealing bead, which applies force on sealing surface

摘要

The exhaust duct system (10) has two exhaust gas guide portions (12,14,16) that are relatively movable, where a sealing element is provided with an end sleeve with a circumferential sealing bead. The circumferential sealing bead applies force on a sealing surface for generating a gas-tight connection formed under a sealing line. The sealing surface is arranged at one of the exhaust gas guide portions and is extended in the region of the sealing line. The sealing element is formed as a one-piece component that is provided with the end sleeve.
