Definitions

  • the invention relates to a filter element for voltage m a filter housing according to the preamble of the claim
  • a filter element is known from EP 0 490 169 B1, the zigzag-shaped filter paths of which are provided with edge elements which act as a sealing surface and which protrude laterally on the filter element from a predetermined area.
  • the edge elements can consist of the same material as the filter element.
  • a frame element for example formed from a urethane foam, covers the edges of the filter element on the upper clamping sides.
  • the frame element is slightly drawn into the lateral and the upper area of the filter element.
  • the invention is based on the object of designing a filter element of the type mentioned at the outset in such a way that, in the case of a simply constructed filter element, the filter element can be clamped in with simple means.
  • the filter element according to the invention is advantageous, in particular for use as an air filter in a motor vehicle, in that the frame elements easily fold a predetermined area on the upper and / or lower side of the filter element into the surface of the filter element.
  • the frame elements are glued or welded to the surface of the filter element and serve laterally as supports for clamping the entire filter element between the housing parts.
  • the filter element can therefore be easily inserted into a housing part without protruding parts clamped and trimmed over the side surface of the frame elements when assembling the housing.
  • the filter element is constructed in a particularly simple manner and, in particular, is also advantageously recyclable if the frame elements and the filter webs are made of the same material, for example of paper.
  • a good strength of the entire filter element is achieved if a cover provided with recesses is attached or glued to the bottom and / or top of the filter element in addition to the frame elements described above, which covers the entire surface and forms parts of the frame elements and the sealing surface at the edges of the surface.
  • the cover can be folded down sideways in a simple manner.
  • the frame elements can be glued or welded to one another at the respective mutually bordering points, all frame elements and possibly the cover being punched out of one piece and folded into the required shape.
  • Figure 1 shows an exemplary embodiment of a filter element with two opposite, folded frame elements
  • Figure 2 shows another embodiment of a filter element with a cover and two frame elements
  • Figure 3 shows a section through a clamping of the filter element in the filter housing.
  • the filter element 1 shows a first exemplary embodiment of a filter element 1, for example for air filtering in the intake tract of a motor vehicle.
  • the filter element 1 has zig-zag folded paper filter sheets 2 through which the air to be filtered passes according to the arrows 3.
  • the filter element 1 also has edge elements 4 and 5 made of paper, which are folded around at the ends 6 and 7 to the filter webs 2 and glued to them.
  • edge elements 8 and 9 are glued to the surface 10 of the filter element 1.
  • the folded ends 7 and the edge elements 8 and 9 also serve as a sealing surface when the filter element 1 is clamped in a filter housing.
  • the cover 11 glued from paper with recesses 12 for the passage of the air to be filtered.
  • the cover 11 is folded down at the edges to form edge elements 13, so that here too a firm bordering of the tracks 2 of the filter element 1 and at the same time a sealing surface is formed on the top of the cover 11, as described with reference to FIG. 1.
  • FIG. 3 shows an example of clamping the filter element 1 between housing parts 14 and 15 of a filter housing.
  • the filter element 1 is clamped tightly and firmly when the housing parts 14 and 15 are joined together by means of an elastic seal 16 with their sealing surfaces (for example 6.7) on the edge elements 4 and 5 or 8 and 9 (not visible here).
  • an elastic seal 16 with their sealing surfaces (for example 6.7) on the edge elements 4 and 5 or 8 and 9 (not visible here).
  • 5 frame elements
  • 7 areas folded over
  • 9 frame elements
  • Housing parts 6 seal

Abstract

L'invention concerne un élément filtrant comportant des bandes filtrantes (2) pliées en zigzag, qui sont maintenues dans un cadre et se fixent avec ce cadre dans un boîtier. Sur au moins deux éléements opposés (4, 5) du cadre, des régions prédéfinies (6, 7) disposées sur la face supérieure et/ou inférieure de l'élément filtrant (1) sont rabattues sur la surface (10) de ce dernier et, au moins à cet endroit là sont collés ou soudés avec l'élément filtrant (1). Ces éléments de cadre (4, 5) servent à soutenir l'élément filtrant (1) lors de sa fixation entre les parties (14, 15) du boîtier.
