Problems solved by technology

[0003] The use of silencers known from the prior art based on the principle of the Helmholtz resonator has the disadvantage that, due to this principle, the sound can only be effectively attenuated in a very limited frequency range
At frequencies outside the frequency range, the attenuation effect is greatly reduced

Embodiment Construction

[0028] The invention presented here relates to turbochargers. The basic structure of a turbocharger is familiar to those skilled in the art. The turbocharger thus has a turbine for the expansion of the first medium, in particular for the expansion of the exhaust gas, where energy is obtained. Furthermore, the turbocharger comprises a compressor for the compression of the second medium, in particular for the compression of charge air, wherein here the energy obtained during the expansion of the first medium in the turbine is regenerated in the compressor in use.

[0029] Turbochargers have different flow directing components. These include in particular the so-called discharge housings of the compressors of the exhaust-gas turbocharger. At least one flow guiding element of the turbocharger is provided with a silencer 1 .

[0030] figure 1 A schematic section through a silencer 1 is shown, which cooperates with a flow guiding element of a turbine, for example with a helical...

Abstract

The present invention relates to turbochargers. Specifically, a turbocharger with a turbine for the expansion of a first medium and for obtaining energy when the first medium expands, and with a turbine for using the energy obtained in the turbine for the compression of a second medium Compressor, wherein at least one flow guiding element of a turbocharger is provided with a silencer (1), wherein the corresponding silencer (1) has a support wall (4) with a A support structure (3) for a cavity (5), wherein the cavity (5) is delimited by a support wall (4) on its side facing away from the flow channel (7) of the muffler (1), and wherein the cavity (5) is bounded on its side facing One side of the flow channel (7) of the muffler (1) is delimited by a cover (8), wherein the cover (8) has at least two mesh-shaped layers (9) with different mesh widths, firmly connected to each other ,10,11).

Description

technical field [0001] The present invention relates to turbochargers. Background technique [0002] A reciprocating piston internal combustion engine with at least one exhaust-gas turbocharger is known from DE 19818873 C2. A muffler is associated with at least one flow guiding element of the exhaust-gas turbocharger, which muffler is based on the principle of a Helmholtz resonator. Here, the corresponding muffler has an outer support wall and a support structure of several cavities received by the support wall, wherein the cavities are delimited by perforated sheets on the side of the muffler facing the flow channel. [0003] The use of sound dampers known from the prior art based on the principle of Helmholtz resonators has the disadvantage that, due to this principle, sound can only be effectively attenuated in a very limited frequency range. At frequencies outside the frequency range, the attenuation effect is greatly reduced. [0004] Continuing from this, the invent...
