Embodiment Construction

[0032] exist Figures 1 to 4 Examples of seals are shown in each case, wherein the seals are each a component part of a sealing device.

[0033] In each of the embodiments shown here, the seal comprises a tubular carrier 1 made of metallic material. The carrier 1 has a groove-shaped groove that is open outwards in the radial direction on the outer peripheral side in the area of ​​its two ends 9, 10, respectively, and an annular sealing body 2, 3. The sealing bodies 2 , 3 each surround the carrier 1 in a hermetically sealed manner.

[0034] The seal shown here is used in the charge air system of a truck or car. In order to be suitable for this application, it is required that the materials used are resistant to high temperatures. "High temperature resistance" means that the materials used are capable of withstanding temperatures up to at least 300°C. For this reason, the use of elastic materials as annular seals 2 , 3 is ruled out.

[0035] In the exemplary embodiment show...

Abstract

A sealing element comprising a tubular carrier (1) and two annular sealing bodies (2, 3), wherein the carrier (1) is surrounded by a sealing body (2, 3) on the outer periphery at the ends of the two sides The sides are airtightly enclosed. At least one sealing body (2, 3) is made of a non-elastic high temperature resistant sealing material.

Description

technical field [0001] The invention relates to a sealing element comprising a tubular carrier and two annular sealing bodies, wherein the carrier is hermetically surrounded on the outer peripheral side by a sealing body at both ends. Background technique [0002] Such seals are known and are designed, for example, as inserts for sealing two housings or pipe joints under pressure and temperature against media such as gases or liquids. The sealing body of known seals is made of elastic material. For applications where the seal is placed between 200°C and 300°C, seals made of elastomeric materials are not suitable as the elastomeric material can be damaged / destroyed during use at these high temperatures. Contents of the invention [0003] The object of the present invention is to further improve the known type of seal in such a way that it reliably seals over a long period of use in the temperature range from 200° C. to 300° C. [0004] This object is solved according to t...
