Abstract

A filter element of a filter device for filtering a fluid may include a ring-shaped filter body from a filter material. The filter body may enclose an interior space in the circumferential direction. A main port may be fluidically connected to the interior space and an auxiliary port may also be fluidically connected to the interior space. The filter body may include a duct that extends axially and is radially open. The auxiliary port may be arranged in a region of the duct.

First claim

The invention claimed is:

1. A filter element of a filter device for filtering a fluid, comprising:
a ring-shaped filter body from a filter material, said filter body having an axis and enclosing an interior space in a circumferential direction,
a main port fluidically connected to the interior space, and
an auxiliary port fluidically connected to the interior space,
wherein the filter body has a duct that extends axially and is radially open, and wherein the duct includes a duct body that has a radially open cross-section profile,
wherein the auxiliary port is arranged in a region of the duct.

2. The filter element according to claim 1 , wherein the auxiliary port is fluidically connected to the interior space via the duct.

3. The filter element according to claim 1 , further comprising at least one end plate axially bordering the filter body, wherein the main port and the auxiliary port are formed on the at least one end plate.

4. The filter element according to claim 1 , wherein
the duct is radially open towards the interior space, and
the auxiliary port is formed on an end plate that axially borders the filter body, wherein the auxiliary port is axially fed through the end plate to be fluidically connected to the duct.

5. The filter element according to claim 1 , wherein the auxiliary port is axially fed between the longitudinal ends of the duct through a duct bottom that borders the interior space such that the auxiliary port is radially fluidically connected to the interior space.

6. The filter element according to claim 5 , wherein the auxiliary port has a port end that is remote from the duct bottom and is oriented radially.

7. The filter element according to claim 5 , wherein
the auxiliary port has a port end that is remote from the duct bottom and is oriented axially,
the duct is radially open towards the outside relative to the interior space, and
the port end is axially fed through a cut-out that is formed in at least one end plate each of which axially borders the filter body.

8. The filter element according to claim 1 , wherein the duct is formed directly by the filter material.

9. The filter element according to claim 1 , wherein the auxiliary port is fed through the duct body to be radially fluidically connected to the interior space.

10. The filter element according to claim 1 , wherein at least one of:
the filter material at least one of lines the duct body on an inner side facing towards the interior space and encloses the duct body on an outer side facing away from the interior space, and
the duct body is arranged in the circumferential direction between circumferential ends of the filter material, wherein the filter material is fastened to the duct body in the circumferential ends.

11. The filter element according to claim 1 , wherein the duct body is integrally formed on at least one of an internal frame on which the filter material is supported radially from the inside, and on at least one end plate that axially borders the filter body.

12. The filter element according to claim 1 , wherein the duct interrupts in the circumferential direction a contour of the filter body, the contour formed by the annularly arranged filter material.

13. The filter element according to claim 1 , wherein the auxiliary port is configured as a nozzle that can be at least one of integrally formed on a duct body and configured as a separate component that is mounted to at least one of the duct body and the filter material.

14. The filter element according to claim 1 , wherein the filter material is a folded web material, and the duct is arranged in the end folds of the filter material.

15. The filter element according to claim 3 , wherein the duct is radially open towards the interior space and the auxiliary port is formed on the at least one end plate axially bordering the filter body, wherein the auxiliary port is axially fed through the end plate to be fluidically connected to the duct.

16. A filter element of a filter device for filtering a fluid, comprising:
a ring-shaped filter body composed of a filter material, the filter body having an axis and enclosing an interior space in a circumferential direction, wherein the filter body includes a duct that extends axially and is radially open;
a main port fluidically connected to the interior space; and
an auxiliary port fluidically connected to the interior space, wherein the auxiliary port is arranged in a region of the duct; and
at least one end plate axially bordering the filter body, wherein the main port and the auxiliary port are disposed on the at least one end plate.

17. A filter element of a filter device for filtering a fluid, comprising:
a ring-shaped filter body composed of a filter material, the filter body having an axis and enclosing an interior space in a circumferential direction, wherein the filter body includes a duct that extends axially and is radially open towards the interior space;
a main port fluidically connected to the interior space; and
an auxiliary port fluidically connected to the interior space, wherein the auxiliary port is arranged in a region of the duct; and
an end plate axially bordering the filter body, wherein the auxiliary port is disposed on the end plate, the auxiliary port being axially fed through the end plate to be fluidically connected to the duct.

18. A filter element of a filter device for filtering a fluid, comprising:
a ring-shaped filter body composed of a filter material, the filter body having an axis and enclosing an interior space in a circumferential direction, wherein the filter body includes a duct that extends axially and is radially open;
a main port fluidically connected to the interior space; and
an auxiliary port fluidically connected to the interior space, wherein the auxiliary port is arranged in a region of the duct; and
wherein the duct interrupts in the circumferential direction a contour of the filter body, wherein the contour is formed by the annularly arranged filter material.

19. A filter element of a filter device for filtering a fluid, comprising:
a ring-shaped filter body composed of a filter material, the filter body having an axis and enclosing an interior space in a circumferential direction, wherein the filter body includes a duct that extends axially and is radially open towards the outside relative to the interior space;
a main port fluidically connected to the interior space; and
an auxiliary port fluidically connected to the interior space and arranged in a region of the duct, wherein the auxiliary port is axially fed between the longitudinal ends of the duct through a duct bottom that borders the interior space such that the auxiliary port is radially fluidically connected to the interior space;
wherein the auxiliary port includes a port end that is remote from the duct bottom and is oriented axially, and wherein the port end is axially fed through a cut-out that is formed in an end plate that axially borders the filter body.
