Abstract

A filter element, including: a first filter medium body having an outflow side and an inflow side; a second filter medium body having an outflow side and an inflow side; wherein the filter element has a longitudinal axis; wherein the first and second filter elements are configured both install into and share in common a filter element housing in which the filter medium bodies delimit a shared common clean space from which the purified fluid is to be discharged via at least one outflow opening; wherein the first filter medium body and the second filter medium body have different sizes and/or different shapes and/or different angular positions of the outflow sides adjoining the clean space.

First claim

What is claimed is:

1. A filter element, comprising:
a first filter medium body having an outflow side and an inflow side;
a second filter medium body having an outflow side and an inflow side;
wherein the filter element has a longitudinal axis;
wherein the first and second filter elements are configured both install into and share in common a filter element housing in which the filter medium bodies delimit a shared common clean space from which the a purified fluid is to be discharged via at least one outflow opening;
wherein the first filter medium body and the second filter medium body have different sizes and/or different shapes and/or different angular positions of the outflow sides adjoining the clean space;
wherein the filter medium bodies have different heights at least in some sections;
wherein an outflow tube attached to the outflow opening runs at least partially above the lower filter medium body;
wherein the outflow tube has a central axis;
wherein the outflow tube runs orthogonally or at an angle greater than 0 degrees and less than 90 degrees relative to an upper side of one of the filter medium bodies.

2. The filter element according to claim 1 , wherein
a diameter and/or a position of the outflow tube is dimensioned and arranged such that the outflow tube does not extend up beyond an upper side of the filter element.

3. The filter element according to claim 1 , wherein the outflow tube runs parallel to a lower one of the filter medium bodies.

4. The filter element according to claim 1 , wherein
at least one of the filter medium bodies has an angular shape.

5. The filter element according to claim 1 , wherein
the filter element includes;
a bottom part; and
a cover part;
wherein the filter medium bodies are accommodate between the bottom part and the cover part.

6. The filter element according to claim 5 , including
guidance elements configured for displaceable guidance of the filter element in a filter housing;
wherein the guidance elements are arranged on the bottom part or on a side part of the filter element.

7. The filter element according to claim 5 , including
guiding elements arranged on opposite side parts of the filter element;
wherein guiding elements extend at an angle relative to the bottom part of the filter element.

8. The filter element according to claim 1 , wherein
the filter element is asymmetrical; and
wherein the outflow sides and/or the inflow sides of the first and second filter medium bodies have different orientations relative to the longitudinal axis of the filter element.

9. The filter element according to claim 8 , wherein
the outflow side of the first filter medium body runs parallel to the longitudinal axis of the filter element; and
the outflow side of the second filter medium body is inclined relative to the longitudinal axis.

10. The filter element according to claim 2 , wherein the central axis of the outflow tube lies outside of the longitudinal axis of the filter element.

11. The filter element according to claim 1 , wherein
the filter medium bodies have pleated filter media,
wherein the pleats run at least approximately orthogonally to the longitudinal axis of the filter element and/or to the outflow direction through the outflow opening in the filter element housing and/or to the central axis of the outflow tube.

12. The filter element according to claim 1 , wherein
the each of the filter medium bodies is a pleated filter having pleated filter media;
wherein the pleated filters have different numbers of pleats and/or the pleats of one pleated filter have a different pleat width from the pleat width of the other pleated filter.

13. A filter device, comprising:
a filter element, including:
a first filter medium body having an outflow side and an inflow side;
a second filter medium body having an outflow side and an inflow side;
wherein the filter element has a longitudinal axis;
wherein the first and second filter elements are configured both install into and share in common a filter element housing in which the filter medium bodies delimit a shared common clean space from which a purified fluid is to be discharged via at least one outflow opening; and
wherein the first filter medium body and the second filter medium body have different sizes and/or different shapes and/or different angular positions of the outflow sides adjoining the clean space;

wherein the filter medium bodies have different heights at least in some sections;
wherein an outflow tube attached to the outflow opening runs at least partially above the lower filter medium body;
wherein the outflow tube has a central axis;
wherein the outflow tube runs orthogonally or at an angle greater than 0 degrees and less than 90 degrees relative to an upper side of one of the filter medium bodies; and

a filter housing receiving and accommodating the filter element.

14. A filter element comprising:
a first filter medium body having an outflow side and an inflow side;
a second filter medium body having an outflow side and an inflow side;
wherein the filter element has a longitudinal axis;
wherein the first and second filter elements are configured both install into and share in common a filter element housing in which the filter medium bodies delimit a shared common clean space from which a purified fluid is to be discharged via at least one outflow opening;
wherein the first filter medium body and the second filter medium body have different sizes and/or different shapes and/or different angular positions of the outflow sides adjoining the clean space;
wherein the filter medium bodies have different heights at least in some sections;
wherein an outflow tube attached to the outflow opening runs at least partially above the lower filter medium body;
wherein the outflow tube has a central axis;
wherein the filter element housing includes a cover part;
wherein the cover part has, between the filter medium bodies, an obliquely-running section into which the outflow opening is incorporated between the first and second filter medium bodies.

15. A filter element comprising:
a first filter medium body having an outflow side and an inflow side;
a second filter medium body having an outflow side and an inflow side;
wherein the filter element has a longitudinal axis;
wherein the first and second filter elements are configured both install into and share in common a filter element housing in which the filter medium bodies delimit a shared common clean space from which a purified fluid is to be discharged via at least one outflow opening;
wherein the first filter medium body and the second filter medium body have different sizes and/or different shapes and/or different angular positions of the outflow sides adjoining the clean space;
wherein the filter medium bodies have different heights at least in some sections;
wherein an outflow tube attached to the outflow opening runs at least partially above the lower filter medium body;
wherein the outflow tube has a central axis;
wherein the filter element includes two adjacent outflow openings.

16. The filter element according to claim 15 , wherein
the two adjacent outflow openings have cross-sections of different sizes.

17. The filter element according to claim 15 , wherein
an outflow tube is associated with each of the two adjacent outflow openings, and the outflow tubes run parallel to one another.
