Abstract

A filter element has a curved filter medium body, which at least partially encloses a flow chamber, and a carrier connector that is guided through the filter medium body. The carrier connector is a carrier of a sealing element for sealing the contact with a flow channel, wherein a section of the sealing element is arranged between the carrier connector and the filter medium body.

First claim

What is claimed is:

1. A filter element for gas filtration, including:
a curved filter medium body, which at least partially encloses an interior flow chamber;
a connector that is guided through the filter medium body and communicates with the interior flow chamber;
wherein the connector forms a carrier connector, to which a separately formed flow channel can be connected;
wherein the carrier connector forms a carrier for a sealing element for sealing between the carrier connector and the flow channel;
wherein the sealing element and/or an additional sealing element are used to provide sealing between the carrier connector and the filter medium body; and
wherein the additional sealing element is arranged on the end face of the carrier connector which faces the interior flow chamber.

2. The filter element according to claim 1 , wherein the sealing element is arranged adjacent to the end face on the carrier connector which faces away from the interior flow chamber.

3. The filter element according to claim 1 , wherein
the sealing element or the additional sealing element is arranged in the region of the two axial end faces of the carrier connector and a remaining sealing element or the additional sealing element is arranged between the carrier connector and the filter medium body.

4. The filter element according to claim 1 , wherein
the sealing element is a saw tooth seal arranged on a wall of the carrier connector.

5. A filter element for gas filtration, including:
a curved filter medium body, which at least partially encloses an interior flow chamber;
a connector that is guided through the filter medium body and communicates with the interior flow chamber;
wherein the connector forms a carrier connector, to which a separately formed flow channel can be connected;
wherein the carrier connector forms a carrier for a sealing element for sealing between the carrier connector and the flow channel;
wherein a support grid is arranged on a flow face of the filter medium body on a side facing the interior flow chamber;
wherein the carrier connector is supported on the support grid.

6. The filter element according to claim 5 , wherein
the carrier connector is arranged in a cut-out of the filter medium body and is completely surrounded by the filter medium body.

7. The filter element according to claim 5 , wherein
the sealing element seals between the carrier connector and the flow channel, the sealing element forming a seal in a radial direction.

8. The filter element according to claim 5 , wherein
for connection, the separately formed flow channel can be pushed into the carrier connector and the sealing element in the carrier connector.

9. The filter element according to claim 5 , wherein
the carrier connector comprises a stop section that projects radially away from a cylindrical wall of the connector for axially supporting the flow channel and/or the sealing element.

10. The filter element according to claim 9 , wherein
the stop section on the carrier connector is a stop leg which is formed in one piece with the wall of the carrier connector.

11. The filter element according to claim 10 , wherein
the stop leg is spaced apart axially away from an adjacent end face of the carrier connector.

12. The filter element according to claim 5 , wherein
the sealing element, on the side facing away from the filter medium body, has a support elevation for supporting a housing component.

13. A filter element for gas filtration, including:
a curved filter medium body, which at least partially encloses an interior flow chamber;
a connector that is guided through the filter medium body and communicates with the interior flow chamber;
wherein the connector forms a carrier connector, to which a separately formed flow channel can be connected;
wherein the carrier connector forms a carrier for a sealing element for sealing between the carrier connector and the flow channel; and
wherein a sealing leg of the sealing element projects into a space between the carrier connector and the filter medium body.

14. A filter element for gas filtration, including:
a curved filter medium body, which at least partially encloses an interior flow chamber;
a connector that is guided through the filter medium body and communicates with the interior flow chamber;
wherein the connector forms a carrier connector, to which a separately formed flow channel can be connected;
wherein the carrier connector forms a carrier for a sealing element for sealing between the carrier connector and the flow channel; and
wherein the sealing element comprises a sealing recess adapted to receive the end face of the carrier connector.

15. The filter element according to claim 14 , wherein
the sealing element comprises a sealing recess adapted to receive the end face of the carrier connector;
wherein the sealing element comprises a second sealing recess adapted to receive the end face of the flow channel;
the sealing recess and the second sealing recess are offset from each other, and open sides of the sealing recess and the second sealing recess are arranged on opposing lateral surfaces of the sealing element.

16. A filter element for gas filtration, including:
a curved filter medium body, which at least partially encloses an interior flow chamber;
a connector that is guided through the filter medium body and communicates with the interior flow chamber;
wherein the connector forms a carrier connector, to which a separately formed flow channel can be connected;
wherein the carrier connector forms a carrier for a sealing element for sealing between the carrier connector and the flow channel; and
wherein the sealing element comprises a sealing recess adapted to receive the end face of the flow channel.

17. A filter device comprising
a filter element for gas filtration, including:
a curved filter medium body, which at least partially encloses an interior flow chamber;
a connector that is guided through the filter medium body and communicates with the interior flow chamber;
wherein the connector forms a carrier connector, to which a separately formed flow channel of a filter housing can be connected;
wherein the carrier connector forms a carrier for a sealing element for sealing between the carrier connector and the flow channel;
wherein the sealing element and/or an additional sealing element are used to provide sealing between the carrier connector and the filter medium body; and

wherein either:
the additional sealing element is arranged on the end face of the carrier connector which faces the interior flow chamber;

or:
a support grid is arranged on a flow face of the filter medium body on a side facing the interior flow chamber; and the carrier connector is supported on the support grid;

a filter housing receiving the filter element and having the separately formed flow channel that can be connected to the carrier connector.
