Definitions

  • the invention relates to an air filter for internal combustion engines, which air filter from one with one to suck in the atmospheric Air suitable inlet connection and with a for Removal of the cleaned air provided with suitable outlet connections House, as well as a filter insert that can be placed in the house, Furthermore, the inlet nozzle is close to one of the end faces of the house, arranged on the outer side wall of the house, in which between the air filter insert and the outlet nozzle located part of the house with an outlet nozzle damper insert provided towards the diffuser channel is.
  • Venturi tubes have been used for a long time used to silence engines and compressors.
  • a these solutions are known from DE 16 69 265 U1, where such the formed against the suction opening "tapered tubes" are either directly to the intake openings the engine blocks arranged or in a common manifold are inserted.
  • the manifold is with branches to the individual Blocks connected.
  • the Venturi tube can also be designed as a tube bundle, the tube bundle either from interlaced, coaxial and in the axial direction conical rings or from side by side Venturi tubes is formed.
  • the filter or between the filter and the internal combustion engine is arranged.
  • the attenuation before the filter and also according to the filter is the attenuation before the filter and also according to the filter.
  • the venturi tube is in a plate filter containing filter housing arranged after the filter.
  • the object of the invention is to eliminate the deficiencies mentioned and to find a solution, besides the noise reduction also the important reduction in pressure vibration for the filters enabled, but the space requirement is not expanded, as well as their production and use is economical.
  • the basis of the invention is the knowledge that the damping of the Air vibrations caused by the engine with a between Venturi tube inserted into the filter and the motor Arrangement can be carried out most effectively and in the case cylindrical ring-shaped inserts is one possibility such vibration damper in the filter house, inside the To arrange use, which in addition to soundproofing Damping of air vibrations caused by the motor is suitable is.
  • the essence of the invention is that the, preferably the full Flow cross section of the house filling damper insert, consisting of several damper insert elements, in the form of inside the cylindrical surface of the filter insert arranged cylindrical Has body and between the damper insert elements in each case an annular gap-shaped opening into a diffuser channel Opening is formed.
  • FIG. 1 shows an axial section of a cylindrical air filter provided with the filter insert manufactured according to one embodiment of the invention
  • FIG 2 shows an axial section of a cylindrical air filter provided with the filter insert manufactured according to another embodiment of the invention
  • in 3 shows an enlarged partial section of the axial section shown in FIG. 2 of the air filter according to the invention you can see.
  • Fig.1 shows a cylindrical house (1). Between the house (1) and one over one of those perpendicular to the axis (2) of the house Cross-section with a smaller cross-section, with the house (1) a coaxial damper insert (3) a filter insert (4) is arranged. To introduce the polluted air to be filtered one at an end face (5) of the house (1), through the side wall of the house (1) leading inlet nozzle (6), also for the The filtered clean air is removed from the other face (7) the house (1) from inside the damper insert (3) Executing outlet nozzle (8) arranged.
  • the cylindrical outer surface of the damper insert is (3) with several in the direction of the axis (9) of the damper insert (3) shifted annular gap-shaped openings (10).
  • the annular gap-shaped opening (10) extends further in the direction of an axis (9) of the damper insert (3), wherein Both edges of the opening (10) are in two trimmed cones continue forming lateral surfaces (11, 12).
  • the angle ( ⁇ ) between the lateral surface (11) closer to the inlet connection (6) and the axis (9) is greater than the angle ( ⁇ ) between the to Inlet nozzle (6) removed outer surface (12) and the axis (9).
  • the annular gap Openings are concentric, i.e. that through the annular gap Openings (10) separate damper insert elements (3a, 3b, ... ..3n) attached to each other, as well as the width of the annular gap Openings (10) can be set separately.
  • the damper insert elements (3a, 3b, ... 3n) can be made hollow so that the axis (9) of the damper insert (3) approach Edges between the two lateral surfaces (11, 12) with cylindrical or conical lateral surfaces (14) are blocked so that the cavities of the damper insert elements (3a, 3b, ... 3n) through the Establishing the ratio between the size of the cordon off Shell surfaces (14) designed opening (s) (15) and the space between the lateral surfaces (11, 12) resonance space (16) be formed.
  • the locking bracket are not shown on the pictures, but the damper insert (3) was interpreted in a form where the locking bracket can be used.
  • Section of a damper insert element (3a, 3b, .. ..3n) takes a teardrop shape after rounding the annular gap Opening (10).
  • the solution is that the damper insert elements (3a, 3b, ... 3n) with a Tool manufactured and with any gap setting can be assembled.
  • the top of the "drop" than that Openings of the damper insert elements (3a, 3b, ... 3n) can be open left, or be decided with restricted area (17), the Openings (15) on the locking surface (17) in the on Fig.1 itself related description can be formed can.
  • venturi tube-like diffuser openings can be dimensioned arbitrarily and in comparison can the larger cross section of the "pipe" between expanded Borders are changed. You have no further space requirements and can be submitted in the types already used.
