Abstract

The invention relates to a supercharging device (1) having at least one pair of two sealing surfaces (2, 3); and having a seal (4) which is arranged between the sealing surfaces (2, 3), characterized in that the seal material of the seal (4) is constructed from sol-gels and/or aerogels.

Description

SUPERCHARGING DEVICE DESCRIPTION The invention relates to a supercharging device according to the preamble of claim 1.
A supercharging device of said type has at least one pair of two sealing surfaces, between which a seal is arranged.
It is therefore an object of the present invention to provide a supercharging device of the type indicated in the preamble of claim 1, which makes it possible to provide a seal which is extremely easy to produce and which exhibits high sealing performance.
This object is achieved by the features of claim 1.
The dependent claims contain advantageous developments of the invention. Since the seal material composed of sol-gels and/or aerogels exhibits specific elastic behavior, it either may be applied directly to the location to be sealed, or may be introduced into a molding tool in order to be able to produce a pre-molded seal by way of a drying process.
If the seal material is applied directly to the sealing surface, it may preferably be sprayed on by means of a spraying apparatus. It is alternatively possible for the seal material to be painted or smoothed on.
If the seal is a seal which is pre-molded in a molding tool, it is possible, in a particularly preferred embodiment of the invention, for said seal to be oriented with respect to the sealing surface by means of fixing points. For this purpose, it is possible for the seal to be equipped with lugs which comprise recesses into which the fixing points for the purpose of orienting the seal can engage.
If the seal material is applied directly to the location to be sealed, such as for example the inlet flange of a turbine housing or the R2S flange of a high-pressure turbine housing to the low-pressure turbine housing, it is possible, in a particularly preferred embodiment, for the seal material to be sprayed directly onto the sealing surface by means of a spraying apparatus.
Claims 8 to 10 define a method according to the invention.
Further details, features and advantages of the invention become apparent from the following description of an exemplary embodiment with reference to the drawing. The single figure of the drawing shows a supercharging device 1 which, in the example, is a two-stage supercharging arrangement with a low-pressure supercharger 1A and a high-pressure supercharger IB.
The figure shows, by way of example, two sealing surfaces 2 and 3 which are intended to be sealed by means of a seal 4. As shown by the figure, the seal 4 is a dimensionally stable prefabricated component which can be oriented with respect to the sealing surface 2 by means of fixing points 5 and 6 in the sealing surface 2 and associated lugs 7 and 8 with corresponding recesses.
It would alternatively be possible for the material of the seal 4 to be applied, for example sprayed by means of a spraying apparatus, directly onto the sealing surface 2 and/or to the sealing surface 3, as has been explained in the introduction.
The sealing surfaces 2 and 3 self-evidently merely constitute an example for illustrating how the seal 4 can be oriented and fixed relative to said sealing surfaces 2 and 3. It is self-evidently possible for all other sealing surfaces of the supercharging device 1 to also be sealed by means of the seal according to the invention.
In addition to the above written disclosure of the invention, reference is hereby explicitly made to the illustrative presentation thereof in the figure.

Claims

1. A supercharging device ( 1 )
having at least one pair of two sealing surfaces (2, 3); and - having a seal (4) which is arranged between the sealing surfaces
(2, 3), characterized
in that the seal material of the seal (4) is constructed from sol- gels and/or aerogels.
2. The supercharging device as claimed in claim 1, characterized in that the seal material of the seal (4) is applied directly to one (2) of the sealing surfaces (2, 3).
3. The supercharging device as claimed in claim 2, characterized in that the seal material of the seal (4) is sprayed, painted or smoothed on.
4. The supercharging device as claimed in claim 1, characterized in that the seal (4) is pre-molded and arranged between the sealing surfaces (2, 3).
5. The supercharging device as claimed in claim 4, characterized in that the seal (4) is oriented with respect to at least one of the sealing surfaces (2, 3) by means of fixing points (5, 6).
6. The supercharging device as claimed in claim 5, characterized in that the seal (4) has lugs (7, 8) which interact with the fixing points (5, 6) and which have receiving recesses for the fixing points (5, 6).
7. The supercharging device as claimed in one of claims 1 to 6, characterized in that the seal material of the seal (4) comprises fibers composed of different fiber materials.
8. The supercharging device as claimed in claim 7, characterized in that the fibers are distributed in a non-specific manner in the seal material.
9. A method for producing a seal (4), having the following method steps:
- providing a seal material composed of sol-gels and/or aerogels;
- introducing the seal material into a molding tool; and
- molding the seal in the molding tool.
10. The method as claimed in claim 9, characterized in that the seal material comprises fibers composed of different fiber materials.
11. The method as claimed in claim 10, characterized in that the fibers are distributed in a non-specific manner in the seal material.
