Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Preferred further developments of the invention may be gleaned from the subclaims and following description. Exemplary embodiments of the invention are explained in greater detail based on the drawing, without being limited hereto. Shown here on:

[0016] FIG. 1 is a cross section through a turbocharger according to prior art;

[0017] FIG. 2 is a perspective view of a silencer of a turbocharger; and

[0018] FIG. 3 is a cross section through the silencer.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS

[0019] The invention relates to a compressor, in particular of a turbocharger, as well as to a silencer of such a compressor. The basic structural design of a turbocharger and silencer of the compressor of the turbocharger was already described in detail drawing reference to FIG. 1. Only those details that distinguish the silencer according to the invention from prior art will be touched upon below.

[0020] FIG. 2 shows a silencer 10 by itself. FIG. 3 shows a cross section through the latter. Visible in FIG. 1 is the front plate 17 of the in particular cylindrical housing 16 of the silencer 10, as is the particular cylindrical circumferential surface 19 extending in the circumferential direction, which outwardly or radially outwardly borders a suction area of the silencer and is defined at least in sections by a filter fleece 20. The filter fleece 20 consists in particular of a plastic, such as polyester. The air to be compressed can be aspirated, and hereby filtered, via the filter fleece 20. The aspirated air can be supplied to the compressor via the recess 20 introduced into the rear plate 18 of the housing 16 of the silencer 10. Flow guiding elements 24 are arranged inside of the housing 16. The air aspirated and filtered in the area of the filter fleece 20 can be guided in the direction of the recess 21 via the flow guiding elements 24.

[0021] In a first aspect, a metal wire component 22 is arranged in the suction area of the silencer 10 or adjacent to the suction area of the silencer 10, in particular immediately underneath the filter fleece 20, as a flame absorber.

[0022] The metal wire component 22 is preferably arranged between the circumferential surface 19, in particular the filter fleece 20, and the flow guiding elements 24 of the silencer 10.

[0023] The filter fleece 20 preferably lies directly outside on the metal wire component 22, which acts as a flame absorber.

[0024] In particular, the metal wire component 22 involves a knitted, crocheted, or braided fabric comprised of wires, preferably of several layers of a knitted, crocheted, or braided fabric comprised of wires, wherein the wires are preferably made out of precious metal.

[0025] The wire component 22, meaning the multilayer knitted or crocheted or braided fabric comprised of metal wires, preferably has a thickness of 50 mm45 mm, preferably a thickness of 50 mm35 mm, especially preferably a thickness of 50 mm25 mm. In particular, the individual layers of the wire component 22 are here coarse-meshed, with a mesh size of up to 10 cm.

[0026] A metal wire component 22 acting as a flame absorber can be used to reliably prevent flames from getting into the environment via the silencer 10 in the event of damage.

[0027] The wire component 22 arranged in the suction area of the silencer 10 or adjacent to the suction area of the silencer 10 impairs neither the acoustic properties nor the flow properties of the silencer 10.

[0028] It is basically possible to arrange the wire component 22 on a side of the flow guiding element 24 in the housing 16 facing away from the filter fleece 20. However, it is preferred that the wire component 22 be arranged on a side of the flow guiding elements 24 in the housing 16 facing the filter fleece 20, i.e., positioned between the circumferential surface 19, in particular the filter fleece 20, and the flow guiding elements 24 of the silencer.

[0029] In a second aspect, an explosion-relief valve 23 with integrated flame absorber is alternatively or preferably also integrated into the front plate 18 of the housing 16, which has the recess 21. This also makes it possible to reliably prevent flames from getting into the environment via the silencer in the event of damage. The explosion-relief valve 23 already opens when exposed to a slight excess pressure, and removes air from the silencer in a defined manner. This makes it possible to counteract the formation of flames.

[0030] The silencer 10 is preferably used on a compressor of a turbocharger. However, the silencer 10 can also be used in other flow machines configured as compressors or superchargers.

[0031] Thus, while there have shown and described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements and/or method steps which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements and/or method steps shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
