    专利说明:

    The invention relates to a muffler of a compressor and a compressor, in particular a turbocharger with a muffler.
    1 shows the basic structure of a turbocharger 1.
    The turbocharger 1 has a turbine 2 for relaxing exhaust gas from an internal combustion engine. Furthermore, a turbocharger 1 has a compressor 3 for compressing air or charge air, using the energy obtained in the turbine 2 during the expansion of the exhaust gas.
    The turbine 2 has a turbine housing 4 and a turbine rotor 5. The compressor 3 has a compressor housing 6 and a compressor rotor 7. The compressor rotor 7 is coupled to the turbine rotor 5 via a shaft 8 which is mounted in a bearing housing 9 , wherein the bearing housing 9 is positioned between the turbine housing 4 and the compressor housing 5 and is connected to both the turbine housing 4 and the compressor housing 5. 1 also shows a compressor-side silencer 10 for sucking in the air to be compressed in the compressor 3.
    The turbine housing 4 of the turbine 2 comprises an inflow housing 11 and an outflow housing 12. The exhaust gas to be expanded in the region of the turbine 2 can be supplied to the turbine rotor 5 via the inflow housing 11. In the region of the turbine rotor 5, relaxed exhaust gas flows away from the turbine 2 via the outflow housing 12.
    The turbine housing 4 comprises, in addition to the inflow housing 11 and the outflow housing 12, an insert 13, the insert 13 running in particular in the region of the inflow housing 11, namely adjacent to the turbine rotor 5, radially outside adjacent to blades 14 of the turbine rotor 5. The turbine housing 4 further comprises a nozzle ring 15. The nozzle ring 15 is also referred to as a turbine nozzle.
    The muffler 10, which serves to suck in the air to be compressed by the compressor, has a housing 16 with a front plate 17 and a rear plate 18. Between the front plate 17 and the rear plate 18 extends a suction area of the muffler 10 delimiting peripheral surface 19 of the silencer 10, which is defined at least in sections by a filter fleece 20. Air to be compressed in the compressor 3 is drawn in via the filter fleece 20, that is to say over the peripheral surface 19 of the muffler 10. The sucked-in air to be compressed can be fed to the compressor 3 via a recess 21 made in the rear plate 18.
    From DE 10 002 581 C2 a turbocharger with a silencer is known.
    In the event of damage, a flame may form inside the compressor. Flames can then escape into the environment via the silencer.
    From DE 19 946 213 C2 an explosion relief valve with an integrated flame absorber is known. The flame absorber is formed from sheet metal strips which are layered one above the other and which are provided with irregular waves over part of their width. Such an explosion relief valve is used on crankcases of internal combustion engines.
    Proceeding from this, the invention has for its object to provide a novel silencer and a novel compressor, in particular a turbocharger. This object is achieved by a silencer according to claim 1 or 10 and a compressor according to claim 11.
    According to a first aspect, a flow-through metallic component, in particular a wire component, is arranged in or adjacent to the suction area of the muffler as a flame absorber. The surface structure of the metallic component, in particular the wire component, is suitable for lowering the temperature of the fluid flow and thereby preventing the escape of flames. According to a second aspect, an explosion relief valve with an integrated flame absorber is integrated in the front panel. With the present invention, a silencer with a flame absorber is proposed. According to the first aspect, the flame absorber is a metal component with a flow through it, which is positioned in the suction area or adjacent to the suction area, in particular below a filter fleece. According to the second aspect, which can also be used in combination with the first aspect, the flame absorber is part of an explosion relief valve which is integrated in the front plate of the housing of the silencer. With both aspects, it can be reliably avoided that in the event of damage, flames get into the environment in an uncontrolled manner through the silencer and thus pose a danger to the operating personnel.
    According to an advantageous development of the first aspect, the flowed through component is a preferably multi-layer knitted fabric or knitted fabric or braid of preferably noble metal wires, which in particular a thickness of 50 mm ± 45 mm, preferably a thickness of 50 mm ± 35 mm, particularly preferably Thickness of 50 mm ± 25 mm. Such a wire mesh or wire mesh or wire mesh can be used in a particularly reliable and simple manner to prevent flames from reaching the surroundings in the event of damage.
    Preferred further developments of the invention result from the dependent claims and the following description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being restricted to this. It shows:

    1 shows a cross section through a turbocharger according to the prior art,
    Fig. 2 is a perspective view of a silencer of a turbocharger
    Fig. 3 shows a cross section through the muffler.
    The invention relates to a compressor, in particular a turbocharger, and a muffler of such a compressor. The basic structure of a turbocharger and the muffler of the compressor of the turbocharger has already been described in detail with reference to FIG. 1. In the following, only those details will be dealt with which distinguish the silencer according to the invention from the prior art.
    Fig. 2 shows a silencer 10 in a single view. Fig. 3 shows a cross section through the same. 1, the front plate 17 of the in particular cylindrical housing 16 of the muffler 10 is visible, as is the circumferentially extending, in particular cylindrical, circumferential surface 19 which defines a suction area of the muffler on the outside or radially outside and is defined at least in sections by a filter fleece 20 is. The filter fleece consists in particular of a plastic such as polyester. The air to be compressed can be sucked in and filtered here via the filter fleece 20. Via the recess made in the rear plate 18 of the housing 16 of the muffler 10, the intake air can be fed to the compressor. Flow guide elements 24 are arranged within the housing 16. The air drawn in and filtered in the area of the filter fleece 20 can be directed in the direction of the recess 21 via the flow guide elements 24.
    According to a first aspect, a metal wire component 22 is arranged as a flame absorber in the suction area of the muffler 10 or adjacent to the suction area of the muffler 10, in particular immediately below the filter fleece 20.
    The metallic wire component 22 is preferably arranged between the peripheral surface 19, in particular the filter fleece 20, and the flow guiding elements 24 of the silencer 10.
    The filter fleece 20 is preferably directly on the outside on the metallic wire component 22, which acts as a flame absorber.
    The metallic wire component 22 is, in particular, a knitted or knitted fabric or braid made of wires, preferably of several layers of a knitted fabric or knitted fabric or braid made of wires, the wires preferably being made of noble metal.
    Preferably, the wire component 22, ie the multi-layer knitted fabric, knitted fabric or braid made of metallic wires, has a thickness of 50 mm ± 45 mm, preferably a thickness of 50 mm ± 35 mm, particularly preferably a thickness of 50 mm ± 25 mm on. The individual layers of the wire component 22 are in particular coarse-meshed with a mesh size of up to 10 cm.
    With a metallic wire component 22, which acts as a flame absorber, it can be reliably avoided that flames get into the environment in the event of damage via the muffler 10.
    The wire component 22 arranged in the suction area of the muffler 10 or adjacent to the suction area of the muffler 10 does not impair the acoustic properties or the flow properties of the muffler 10.
    In principle, it is possible to arrange the wire component 22 in the housing 16 on a side of the flow guide elements 24 facing away from the filter fleece 20. However, it is preferred to arrange the wire component 22 on a side of the flow guide elements 24 facing the filter fleece 20 in the housing 16, that is to say to position it between the peripheral surface 19, in particular the filter fleece 20, and the flow guide elements 24 of the muffler 10.
    Alternatively or preferably additionally, according to a second aspect, an explosion relief valve 23 with integrated flame absorber can be integrated into the front plate of the housing 16 of the muffler 10, that is to say opposite the rear plate 18 of the housing 16, which has the recess 21. This also reliably prevents flames from reaching the surroundings via the silencer in the event of damage. The explosion relief valve 23 opens at a slight overpressure and discharges air from the silencer in a defined manner. As a result, the formation of flames can be counteracted.
    The muffler 10 is preferably used on a compressor of a turbocharger. However, the muffler 10 can also be used in other flow machines designed as compressors or compressors.
