Definitions

  • the invention relates to a filter element for an air filter with a folded filter insert, in particular for filtering the intake air of an internal combustion engine, according to the preamble of the main claim and the method claim.
  • filter elements in particular for use in internal combustion engines in trucks and construction machinery, are manufactured with a relatively large filter area. These filter elements are provided on one side with a seal that runs at least around the edge in order to seal the raw air side from the clean air side.
  • the known filter element can be designed in such a way that certain geometries in the filter housing or on the adjoining units are taken into account by combining individual filter elements with different pleat heights.
  • the individual filter elements are each manufactured separately and connected to each other via additional connecting webs, which also act as a hinge.
  • the invention is based on the object of designing a filter element of the type specified at the outset in such a way that an easily adjustable contour of the folded filter insert can be achieved.
  • the pleated filter insert advantageously has on one side a surface which at least partially deviates from a plane and thereby has a continuous zigzag fold.
  • the filter element can be easily adapted to complex structures in the intake area of an internal combustion engine in order to optimize the filter effect by making better use of space in the area of this side of the filter insert. Due to the good contact of the filter element with the geometry in the intake path, the invention also serves to improve the flow behavior on this air inlet side of the filter element.
  • bevels, angular or curved contours can also be provided on the corresponding side of the filter insert, the largely zigzag folding ensuring a largely uniform filter effect over the entire filter surface.
  • fold areas of the filter insert are prefabricated with different fold heights and, when the filter element is assembled, glued, punched or otherwise firmly connected to the adjacent folds.
  • Figure 1 shows a first embodiment with a stepped contour on one side of the filter insert
  • Figure 2 shows another view of the embodiment of Figure 1;
  • Figure 3 shows a second embodiment with an oblique contour on one side of the filter insert;
  • Figure 4 shows a third embodiment with a curved contour on one side of the filter insert
  • Figure 5 shows a fourth embodiment of a filter element with areas of different folding direction of the areas of the filter insert
  • Figure 6 is an illustration of the embodiment of Figure 2 with parts of a housing
  • Figure 7 is an illustration of the embodiment of Figure 3 with parts of a housing.
  • FIG. 1 shows a section through a filter element 1 with a zigzag-shaped filter insert 2, which has on its underside a fold area 3 with a relatively low fold height and a fold area 4 with a relatively large fold height.
  • FIG. 2 shows a view of the filter element 1 in which a fold area 5 is also present on the right with a small fold height.
  • these areas can be arranged at different points depending on the application.
  • the filter element 1 has on its upper side a circumferential seal 6 with which the filter element 1 is inserted into a filter housing (not shown here) for an air filter. ter can be inserted tightly in the air intake path of an internal combustion engine. The sucked-in unfiltered air flows through the filter element 1 according to an arrow 11 from one contour-adapted side to the other, here upside, whereby optimal flow conditions occur here due to the contour of the one side of the filter insert _2, which is adapted to the geometry of the suction path.
  • the filter insert 2 according to FIGS. 1 and 2 can be produced in such a way that the individual regions 3 and 4 are produced separately and then the respectively adjacent folds of the fold regions 3, 4, 5 are connected to one another.
  • a filter element 7 is provided with a filter insert 8 which runs beveled on the contour-adapted side.
  • the fold height which changes here in the course of the surface of this side of the filter insert 8 can be achieved by changing the fold spacing when folding the paper or nonwoven webs, starting from the folding method known per se (DE 42 23 723 C2) in the introduction to the description .
  • one side of a filter insert 10 is also curved accordingly.
  • This changing curvature can also be produced, for example, by a correspondingly controlled change in the fold spacing or the pre-embossing during the folding process.
  • FIG. 5 shows the filter element according to FIG. 2 with a housing 20, in which the raw air enters laterally according to an arrow 21.
  • FIG. 7 shows the filter element according to FIG. 2 with a housing 20, in which the raw air enters laterally according to an arrow 21.

Abstract

L'invention concerne un élément filtrant pour filtre à air, constitué d'une cartouche filtrante (2; 8; 10) pourvu de plis en zigzags, en papier filtre ou en non tissé filtrant, et d'un joint (6) s'étendant sur les bords extérieurs du côté plat de la cartouche filtrante (2; 8; 10), joint par l'intérmédiaire duquel l'élément filtrant (1; 7; 9; 10) repose sur une partie d'un corps de filtre. La cartouche filtrante à plis (2; 8; 10) présente, sur un côté, un contour s'écartant, au moins dans des zones prédéfinies, en ce qui concerne la surface, d'un plan, et également un pliage en zigzags allant d'un bord à l'autre.
