Definitions

  • the present invention relates to a silencer for airborne sound conducting pipe system, in particular for an exhaust system, preferably in an internal combustion engine.
  • mufflers are used to avoid unwanted noise emission into the environment.
  • silencers which work according to the absorption structure or the reflection construction or combinations thereof. In this construction results in respect of the attenuated frequencies in a substantially constant damping effect.
  • the spectrum of disturbing sound varies relatively strong, since it is speed and load-dependent. For example, significantly dominated engine orders have excessive sound pressure levels.
  • mufflers may include at least one flap with which a gas flow path in the muffler is controllable.
  • active systems in which an external control for actuating an actuator driving the respective flap is required
  • passive systems are known in which the respective flap is actuated by the gas flow. With the help of such a flap, the damping effect and the counter-pressure behavior of the muffler can be influenced.
  • active systems are relatively expensive in terms of manufacturing costs due to the required additional active control components, such as control unit, vacuum unit, vacuum line, switching valve.
  • a silencer with an active system In the DE 19540716 is proposed a silencer with an active system. Passive systems are less expensive than active systems, but may be more or less complicated and / or develop only a comparatively low acoustic effect and / or produce a comparatively high counterpressure and / or have a comparatively large volume of construction.
  • the present invention is concerned with the problem of providing an improved embodiment for a silencer, which is characterized in particular by the fact that it is comparatively inexpensive and / or comparatively compact and / or has a comparatively high acoustic effect with a favorable counterpressure behavior.
  • the present invention is based on the general idea, in a silencer whose inlet pipe is equipped with a passive operating switching element, branch off a bypass pipe from the inlet pipe upstream of the switching element and form or arrange the pipe system in the housing so that the interior of the housing, ie substantially the entire silencer volume is acoustically effective when the switching element is open and closed.
  • the switching element remains closed and the gas flow and the airborne sound transported therein are - except for unavoidable leaks at the flap - passed exclusively through the bypass pipe. This makes it possible to achieve a comparatively high acoustic damping effect.
  • the respective switching element is open, so that the gas flow and the airborne sound transported therein largely passes over the controlled by the switching element end portion of the inlet pipe into the interior of the muffler.
  • the exhaust backpressure is comparatively low.
  • the acoustic effect of the muffler can be designed in this case so that it can still be accepted for the particular application of the muffler. Due to the proposed construction of the muffler has a relatively simple and suitable for different applications and in so far universal structure. In particular, the Silencer by the one acoustically undivided interior inexpensive to produce.
  • the proposed muffler is characterized by a high acoustic damping effect at low gas flow, as they occur, for example, at low speeds and operating loads of an internal combustion engine.
  • the proposed muffler is characterized by a comparatively low flow noise and by a relatively low back pressure, which is achieved in particular by the use of the acoustically undivided interior.
  • the installation space is lower than in conventional mufflers, which have comparable acoustic properties without switching elements and / or a comparable low back pressure.
  • the outlet of the inlet pipe, the outlet of the bypass pipe and the respective inlet of the at least one outlet pipe may be arranged acoustically in the same space or volume.
  • the muffler may include at least one absorption sleeve, which in at least an outlet tube encloses an axial section extending in the interior and is acoustically coupled to the interior of the respective outlet tube.
  • at least one absorption chamber may be formed in the housing, which is acoustically coupled to the rest of the interior.
  • the respective absorption sleeve or the respective absorption chamber are arranged in a shunt and thus influence neither the gas flow nor the sound propagation, neither with the door open nor with the door closed. They bring about an intensive damping of high-frequency flow noise, which can occur in particular when flowing around the respective switching element.
  • a muffler 1 comprises a housing 2 which encloses an interior space 3.
  • the muffler 1 is suitable, for example, for damping airborne noise in a pipe system that carries airborne sound or in which airborne sound can propagate.
  • a pipe system that carries airborne sound or in which airborne sound can propagate.
  • Such pipe systems can be found for example in turbo groups of power plants and in internal combustion engines, namely in a fresh gas system or in an exhaust system.
  • Preference is given here to the use of the muffler 1 in an exhaust system of an internal combustion engine, which may be arranged in particular in a motor vehicle.
  • the silencer 1 further comprises an inlet pipe 4, which has at least one outlet 5 in the interior 3, which is preferably axially open.
  • inlet pipe 4 which has at least one outlet 5 in the interior 3, which is preferably axially open.
  • more than one inlet pipe 4 may be provided.
  • the embodiment shown here is preferred with only a single inlet pipe 4.
  • From the inlet pipe 4 branches off a bypass pipe 6, within the housing 2 and preferably in the interior 3.
  • the bypass pipe 6 has in the interior 3 at least one outlet 7, which preferably axially open.
  • from the respective inlet pipe 4 or branch off from the inlet pipes 4 also a plurality of bypass pipes 6.
  • the embodiment shown here in which only a single bypass tube 6 is provided is preferred.
  • the bypass pipe 6 is substantially perpendicular from the inlet pipe 4; other angles are possible.
  • a switching element 8 is arranged, which is actuated as a function of the gas flow, that is, as a function of the gas mass flow.
  • the switching element 8 is a flap, which is driven by gravity and / or spring-loaded in a closed position shown by a solid line and which can be driven by the flow forces more or less to open.
  • an open position is shown with a broken line.
  • the passively operating switching element 8 opens more or less, whereby the gas flow and thus the airborne sound more or less controlled by the switching element 8, downstream of the bypass tube 6 end portion of the inlet tube 4 and thus flows through the outlet 5 of the inlet pipe 4. From a certain size of the gas flow or from a certain gas mass flow, the gas flow and thus also the entrained airborne sound largely enters the interior 3 through the outlet 5 of the inlet pipe 4.
  • a corresponding flow path or airborne sound propagation path is indicated in the figures by broken arrows.
  • Fig. 1 shows an embodiment in which the switching element 8 is arranged directly at the outlet 5 of the inlet pipe 4.
  • the switching element 8 can be particularly easily attached to the inlet pipe 4 in this construction.
  • Fig.2 By way of example, an embodiment in which the switching element 8 is installed in the inlet pipe 4, that is, is located downstream of the associated outlet 5. This design can for example offer space advantages.
  • the silencer 1 also has at least one outlet pipe 9, which has at least one inlet 10 in the interior 3, which is preferably axially open.
  • outlet pipe 9 which has at least one inlet 10 in the interior 3, which is preferably axially open.
  • only a single outlet pipe 9 is shown.
  • designs are conceivable in which more than one outlet pipe 9 is provided.
  • the muffler 1 is characterized in particular by the fact that the interior 3, in which the outlet 5 of Inlet pipe 4, the outlet 7 of the bypass pipe 6 and the inlet 10 of the outlet pipe 9 are acoustically undivided.
  • the said openings or pipe ends 5, 7, 10 are acoustically in the same space, namely in the interior 3 or in the same acoustic volume, namely in the volume of the interior 3.
  • the impact of airborne sound volume of the interior 3 is independent of the operating state of the switching element 8 always the same size.
  • the airborne sound can propagate in the entire acoustic volume of the interior 3 both with the switching element 8 open and closed. This design leads to a relatively small space requirement of the muffler 1.
  • the bypass pipe 6 is dimensioned such that a flow of the muffler 1 adjusts from a predetermined gas flow, in which the gas flow and thus the entrained airborne sound passes mainly through the outlet 5 of the inlet pipe 4 into the interior 3.
  • this is a cross section 11 or - in a circular cross section - a diameter 11 of the bypass tube 6 smaller than a cross section 12 or - in a circular cross section - a diameter 12 of the inlet tube 4.
  • an axial length 13 of the bypass tube 6 at least equal be as the diameter 12 of the inlet pipe 4. In the examples shown, the axial length 13 of the bypass pipe 6 is greater than the diameter 12 of the inlet pipe 4th
  • the outlet pipe 9 is equipped inside the housing 2 with an absorption sleeve 14. This encloses in the interior 3 an axial section of the outlet pipe 9.
  • the axial section of the outlet pipe 9 enclosed by the absorption sleeve 14 has a perforated wall 15, whereby the absorption sleeve 14 or its annular space 16 is acoustically coupled to the interior of the outlet pipe 9.
  • the annular space 16 may be filled or stuffed with a sound-absorbing substance 17, in particular a porous absorption material.
  • the muffler 1 have at least one absorption chamber 18 which is arranged in the housing 2.
  • the absorption chamber 18, which in particular can be filled again with a sound-absorbing substance 17, is bounded here by a perforated wall 19 and by the housing 2.
  • the absorption chamber 18 is formed in the region of a bottom 20 of the housing 2, so that the respective housing bottom 20 with adjoining sections of a housing jacket 21 delimits the respective absorption chamber 18.
  • this or another absorption chamber along the (entire) housing shell 21 may be arranged so that the housing shell 21 and in particular edge regions of the housing bottoms 20 limit the absorption chamber.
  • the at least one perforated wall 19 used to confine the absorption chamber 18 is positioned so as to be between the respective absorption chamber 18 and the Outlet 5 of the inlet pipe 4, the outlet 7 of the bypass pipe 6 and the inlet 10 of the outlet pipe 9 is located.
  • the absorption chamber 18 is thus arranged in shunt and is not flowed through. This also applies to the absorption sleeve 14.
  • the housing 1 may be stiffened with at least one perforated intermediate bottom 22.
  • the end portions of the inlet pipe 4 and the at least one outlet pipe 9 may be supported.
  • the outlet 5 of the inlet tube 4 and the inlet 10 of the outlet tube 9 are arranged and / or aligned relative to one another in the interior 3 such that a gas flow in the interior 3 has to reverse its flow direction twice by approximately 180 ° in order to exit from the outlet 5 of the inlet pipe 4 to the inlet 10 of the outlet pipe 9 to arrive.
  • outlet 7 of the bypass tube 6 and the inlet 10 of the outlet tube 9 in the interior 3 are arranged or oriented relative to each other so that the gas flow in the interior 3 is not their flow direction or - as here - only once by about 90 ° or less to change from the outlet 7 of the bypass pipe 6 to the inlet 10 of the outlet pipe 9.
  • the selected arrangements of the respective pipe ends or openings 5, 7, 10 contribute to the fact that in the respective operating state, thus depending on the gas mass flow, sets the desired effective damping or the desired comparatively low back pressure.
  • the silencer 1 comprises an assembly 23 which forms a unit which can be pre-assembled separately or independently with respect to the other components of the silencer 1.
  • This assembly 23 includes an end portion 24 of the inlet pipe 4, which includes the bypass pipe 6 and the switching element 8.
  • This assembly 23 is designed so that it can be relatively easily attached to a terminal end 25 of the remaining inlet pipe 4. For example, a plug connection is conceivable here.
