Abstract

The invention relates to a seal system, in particular, for joint connections on hot gas flow paths, such as exhaust systems on internal combustion engines, comprising a seal support (3) and at least one seal element (1) defining a seal plane lying between sealing surfaces, characterised in that the seal support (3) is a separate component from the seal element (1) as a further separate component and that in order to obtain the seal system both components are non-detachably connected to each other.

Description

technical field

[0001] The invention relates to a sealing system, in particular for an interface connection on a flow path of a hot gas, such as an exhaust gas flow of an internal combustion engine, comprising a sealing seat and at least one sealing element defining a sealing plane between sealing surfaces . Background technique

[0002] Interface connections to be sealed in the area of ​​hot gases, such as in internal combustion engines, for example at the manifold outlet, at the turbocharger, at the catalytic converter or also in the connection area between the cylinder head and the exhaust gas manifold In this case, high thermal and mechanical loads occur, so that a high structural outlay is required for the associated sealing system. Metal seals made of heat-resistant alloy materials must be used as sealing elements, wherein the exhaust gas-conducting connecting parts must have a groove or a step for an associated annular sealing element in their function as a sealing s...
