Definitions

  • Air filter for internal combustion engines provided with a damper
  • the invention relates to an air filter provided with a damper element for internal combustion engines, which air filter also consists of a house provided with an inlet connection suitable for sucking in the atmospheric air and with an outlet connection suitable for removing the cleaned air, as well as a filter insert which can be placed in the house the inlet connector is arranged on the surroundings of one of the end faces of the house, on the outer side wall of the house.
  • the object of the invention is to abolish the abovementioned shortcomings and to provide a solution which, in addition to the reduction in noise, also enables the pressure oscillation to be reduced, which is important for the filters, but does not expand the space, and their production and use are economical.
  • the basis of the invention is the knowledge that the filtration can be carried out with the best efficiency in the case of a static air flow, since in the pulsating air flow significantly more contaminants get over on the side of the cleaned air. " It was recognized that the damping of the air vibrations caused by the engine can be carried out most effectively with a venturi tube-like arrangement between the filter and the engine, and in the case of cylindrical ring inserts there is a possibility of a vibration damper in the filter house in which To arrange the interior of the insert.
  • the essence of the invention is that in the part of the house located between the air filter insert and the outlet connection, there are damper inserts (set) provided with diffuser openings widening against the outlet connection, preferably filling the full flow cross-section of the house. .
  • FIG.l a Axial section of a cylindrical air filter provided with the filter insert manufactured according to an embodiment of the invention, in
  • FIG. 2 shows an axial section of a cylindrical air filter provided with the filter insert manufactured according to another embodiment of the invention
  • FIG. 3 shows an enlarged partial section of the axial section shown in FIG. 2 of the air filter according to the invention.
  • Fig.l shows a cylindrical house (1).
  • a filter insert (4) is arranged between the house (1) and a damper insert (3) which is smaller than the cross section perpendicular to the axis (2) of the house and coaxial with the house (1).
  • To introduce the polluted air to be filtered there is an inlet connection (6) at one end face (5) of the house (1), through the side wall of the house (1), and also for the removal of the filtered clean air at the other end face (7) of the house (1) from the interior of the damper insert (3) performing outlet nozzle (8).
  • the cylindrical outer surface of the damper insert (3) is provided with a plurality of circular openings (10) displaced in the direction of the axis (9) of the damper insert (3), the two circular edges of which in the direction of the outlet connector (8) in two outer surfaces similar to the trimmed cone (11,12) can be continued.
  • the angle ( ⁇ ) between the lateral surface (11) closer to the inlet connection (6) and the axis (9) is greater than the angle ( ⁇ ) between the lateral surface (12) remote from the inlet connection (6) and the axis (9) .
  • This means that the distance between the lateral surfaces of the two trimmed cones is 4 voltage (10) in the direction of the interior of the damper insert (3) is enlarged and a diffuser channel is formed.
  • the circular openings (10) are concentric, which means that the fastening of the damper insert elements (3a, 3b, ... 3n) separated by the circular openings (10) and thus the setting of the width of the circular openings (10) should be solved separately. According to the example, this is done with tabs applied to the outer lateral surfaces of the damper insert (3) in the direction of the jacket line or with the tabs inside the damper insert (3) on the jacket surfaces (11, 12) in the direction of the jacket surface of the damper insert (3) arranged openings implemented floors (13).
  • the damper insert elements (3a, 3b, ... 3n) can be made hollow so that the edges closer to the axis (9) of the damper neck (3) between the two lateral surfaces (11, 12) similar to the trimmed cone with cylindrical or conical lateral surfaces (14) are blocked so that the cavities of the damper insert elements (3a, 3b, ... 3n) with the determination of the relationship between the size of the opening (s) (15) and the Space between the outer surfaces (11, 12) of the resonance chamber (16) are formed.
  • a locking bracket with a cross section extending in the direction of the outlet connection (8) is arranged inside the damper insert (3).
  • the lateral surfaces (14) are also conical, and are to be made expanding in the direction of the outlet connection (8).
  • the locking bracket is not shown in the illustrations, but the damper insert (3) was interpreted in a form where the locking bracket can be used.
  • the lateral surfaces (11, 12) form a conical lateral surface which bulges out in the direction of the diffuser channel and thus forms an axis (9).
  • 5 holding section of each damper insert element (3a, 3b, ... 3n) takes a teardrop shape after rounding at the circular opening (10).
  • the damping insert members (3a, 3b, ... 3n) provided with a tool manufacturer and assembled with any gap adjustment who the can ⁇ .
  • the tip of the "drops" as the openings of the damper insert elements (3a, 3b, ... 3n) can be left open, or can be decided with a blocking surface (17), the openings (15) on the blocking surface (17) being open in the shown in Fig.l related description can be formed.
  • venturi tube-like diffuser openings can be dimensioned as desired and, in comparison, the larger cross-section of the "tube” can be changed between extended limits. They have no further space requirements and can be submitted in the types already used.

Abstract

L'invention concerne un filtre à air doté d'un organe amortisseur et destiné à des moteurs à combustion interne. Ce filtre à air comprend un carter (1) doté d'une tubulure d'entrée (6) destinée à l'aspiration de l'air atmosphérique et d'une tubulure de sortie (8) destinée de l'évacuation de l'air purifié. Ce filtre à air comprend également un insert filtrant (4) logé dans le carter (1). La tubulure d'entrée (6) est située sur la paroi latérale extérieure du carter (1) à proximité de l'une des faces frontales du carter (1). L'invention est caractérisée en ce que la partie du carter (1), située entre l'insert filtre à air (4) et la tubulure de sortie (8), est dotée d'au moins un insert amortisseur (3) qui est pourvu d'orifices de diffusion orientés vers la tubulure de sortie et s'étalant de préférence sur toute la section transversale d'écoulement du carter (1).
