Definitions

  • the invention relates to a filter silencer, as in The preamble of the first claim is described.
  • Such a filter silencer is known, for example from EP 0574605 A1.
  • Filter silencers of this type are used, for example, on the intake side of a compressor which compresses combustion air and supplies it to an internal combustion engine.
  • a compressor is driven by the exhaust gas turbine of an exhaust gas turbocharger.
  • Mainly in the compressor wheel there are sound waves of undesirable high amplitude, which are released to the environment through the air intake duct. These sound waves are therefore usually attenuated by means of a silencer.
  • ambient air flows through a filter arranged on the circumference of a muffler into the interior of the muffler equipped with damping elements, then flows past the damping elements, and is deflected by guide elements to the compressor wheel, from which sound waves emanate against the air flow.
  • the sound damping takes place dissipatively on the damping elements, in that the sound energy is converted into heat directly by porous or fibrous absorption materials, from which the damping elements are essentially constructed.
  • the above-mentioned EP 0574605 A1 describes a filter silencer which consists of a cast monoblock and in whose radial ribs the grooves are arranged with grooves.
  • a filter frame consisting of a removable perforated sheet metal part, surrounds the silencer in such a way that the damping elements are secured against radial falling out.
  • the perforated sheet metal part is arranged in a ring around the silencer by means of connecting elements.
  • a disc-shaped damping element consists of four damping segments, which together form an annular surface.
  • An absorption element is held by two punched perforated sheets, and thus forms a damping segment which is radially inserted into the grooves of the above-mentioned ribs of the cast monoblock.
  • edges of the damping segments punched out of perforated sheet have a disadvantage in the construction of this filter silencer.
  • These edges of the damping segments in the form of ring segments are not treated further after punching out, and thus have free-standing sheet metal webs due to the sheet metal perforation.
  • These sheet metal webs can break off due to mechanical vibrations to which the entire filter silencer is exposed, and then the broken off pieces with sucked-in air can get into the compressor and into the combustion chamber of an internal combustion engine and damage them.
  • the damping material then swells and thus impairs the air inlet channels with regard to the flow properties.
  • the deflection by guide elements on the damping elements also has an unfavorable effect on the flow properties of the air, since it causes compression losses of undesirable height.
  • the invention has for its object a filter silencer to further develop the type mentioned at the beginning, that the disadvantages mentioned above are reduced or be avoided. At the same time, the damping properties the silencer can be improved, and the Manufacturing and assembly costs can be reduced.
  • the closed edges of the are also advantageous Damping plates that run along the perforated plate webs, and therefore have no free-standing metal webs.
  • the coarse filter that surrounds the sports silencer is segment by segment divided, and the segments are on the damping plates arranged so that the coarse filter is not required as a single component.
  • the arrangement of a cast-in is also advantageous Rohres as a washing device for the compressor wheel in the Housing wall of the connection side of the filter silencer.
  • This pipe is connected to a supply line that does not like with conventional silencers, guided around them must be because their connection to the washing device on the end of the filter silencer is arranged.
  • Fig. 1 shows a cylindrical filter silencer, which is essentially composed of a housing 2, a number, here thirty-three, damping elements 3 and a filter 4.
  • 2 shows the housing 2 cast as a monoblock made of aluminum, the housing wall 5 of which is connected on the connection side 20 of the filter muffler by means of connecting webs 7 to the housing wall 6 on the end side 21.
  • Circular arc-shaped grooves 8 are cast in on the inner sides of the housing walls 5, 6 and run narrower towards the inner radius of the filter muffler.
  • the cross-sectional area of a connecting web 7 is the same in shape and curvature of a groove 8, and the distribution of the thirty-three grooves 8 and the three connecting webs 7 has been made uniformly over the circumference of the housing in a 10 ° division.
  • webs 14 are arranged which have a constant width from the outer circumference of the housing 2 to the inner radius in FIG.
  • a connection flange 22 is arranged on the connection side 20, with which the filter silencer is mounted on the compressor side of an exhaust gas turbocharger, not shown here. As shown in FIG.
  • a tube 18 with a thread 19 is cast into the housing wall 5 on the connection side 20 in the radial direction, which is angled toward the connection side 20 at the end pointing to the central axis 13 of the housing 2.
  • This tube serves as a washing device for the compressor wheel, not shown here, and is connected directly to the thread 19 with a line, also not shown, on the connection side 20 of the filter silencer.
  • the damping elements 3 are secured with straps 16, which are closed on the circumference of the housing 2 by means of quick-release fasteners 17, against falling out.
  • the filter muffler is surrounded on its circumference by an annular filter 4 made of polyurethane foam (PU foam), which filters out particles in the ambient air drawn in.
  • the circumference of the annular filter 4 is smaller than the outer circumference of the filter muffler in the unassembled state, so that the filter 4, which is made of PU-elastic rubber, is fixed to the circumference of the muffler by spring force.
  • PU foam polyurethan
  • damping plate 9 is punched during manufacture in the form of a rectangle from perforated plate with square holes along the perforated webs, and thus has no free-standing webs.
  • the rectangular perforated plate is then bent in such a way that a concave surface 12 is formed, to which a convex surface 11 adjoins.
  • a flat surface 15 adjoins the convex surface 11 and is bent as a coarse filter segment 15.
  • the concave surface 12 and the convex surface 11 run approximately parallel and form an intermediate space 23 into which the absorption element 10, FIG. 5, is inserted.
  • An absorption element 10 is thicker than the intermediate space 23, so that when an absorption element 10 is inserted into the intermediate space 23, the surfaces 11, 12 are to be elastically bent apart. After the absorption elements 10 have been inserted into the intermediate space 23, they are clamped between the surfaces 11, 12 on account of their thickness.
  • the material used for an absorption element 10 is an open-cell foam which, with the same damping properties, has only about 6% of the specific weight of conventional absorption materials such as wool felt.
  • the absorption elements 10 shown in FIG. 5 are cut out rectangularly from foam sheets and are shown here only as bent in their installed state.
  • FIG. 6 shows the arrangement of the damping elements 3, consisting of the damping plate 9 and the absorption element 10, in the circular cylindrical housing 2 with the central axis 13 on the basis of a cross-sectional segment of a filter muffler.
  • the damping elements 3 are radially inserted into the grooves 8 and are of the type arranged that their damping surfaces 11, 12 run parallel to the central axis 13 of the housing 2.
  • the width of the webs 14, and thus also the cross-sectional area of the air inlet ducts 24 between adjacent damping elements 3, is constant from the outer circumference of the filter muffler to the central axis 13, which ensures a constant speed of the ambient air drawn in. This arrangement reduces compression losses that occur in conventional silencer systems.
  • the coarse filter segments 15 of the built-in damping plates 9 are combined to form a coarse filter ring, so that a coarse filter as an individual component is not required.
  • An arc-shaped arrangement of the damping elements 3 in the housing 2 extends the air inlet ducts 24, and thus the path of the sound waves, in comparison to purely radial air inlet ducts, as occur in conventional filter silencers with the same outer circumference. This extension of the damping path alone, with the same dimensions as conventional filter silencers, improves sound absorption.
