Abstract
A filtering system may include a holder and an exchangeable filter element. The filter element may include a first end plate, a second end plate, and a filtering material arranged between the first end plate and the second end plate that separates a filtered zone from an unfiltered zone. The second end plate may protrude beyond the filtering material. The filtering system may further include at least one filtered opening and at least one unfiltered opening, and the at least one filtered opening may be disposed in the filter element. The filter element may lie detachably on the holder, and the holder together with the second end plate, the filtering material and an outer wall may enclose the unfiltered zone.
Claims20
A filtering system for a motor vehicle, comprising:
- a holder and an exchangeable filter element, the filter element including a first end plate, a second end plate and a filtering material arranged between the first end plate and the second end plate that separates a filtered zone from an unfiltered zone;
- at least one filtered opening and at least one unfiltered opening, the at least one filtered opening disposed in the filter element, wherein the filter element lies detachably on the holder;
- at least the second end plate protrudes beyond the filtering material;
- the holder, the second end plate, the filtering material and an outer wall enclose the unfiltered zone;
- the unfiltered zone defined between the filtering material and the outer wall;
- the outer wall runs along a course of the filtering material;
- the outer wall runs transversely to the first end plate and the second end plate;
- and
- wherein one of:
- the outer wall is disposed securely on the second end plate, and the outer wall lies loosely on the holder;
- and
- the outer wall is disposed securely on the holder, and the outer wall lies loosely on the second end plate.
A method for the production of a filter element of a filtering system, comprising:
- providing a first end plate, a second end plate, and a filtering material arranged between the first end plate and the second end plate to separate a filtered zone from an unfiltered zone, wherein at least the second end plate protrudes beyond the filtering material;
- providing an outer wall extending along the filtering material between the first end plate and the second end plate, the outer wall extending transversely to the first end plate and the second end plate, wherein the unfiltered zone is defined between the filtering material and the outer wall, and wherein the outer wall is secured to one of the second end plate and a holder, and the outer wall lies loosely against the other of the second end plate and the holder;
- wherein providing the outer wall includes forming the outer wall from a functional strip;
- and
- joining the functional strip by plasticizing at least to the second end plate.
