Abstract

A filter housing for receiving a filter element is provided with a first housing part having a first housing opening and a second housing opening. A second housing part is connected to the first housing part. A first connecting socket is arranged at the first housing opening of the first housing part. A second connecting socket is arranged at the second housing opening of the first housing part. A receiving space is provided in an interior of the filter housing between the first and second housing openings, wherein the receiving space accommodates the filter element.

First claim

What is claimed is:

1. A filter housing for receiving a filter element, the filter housing comprising:
a two part housing having
a first housing part; and
a second housing part;
wherein one of the housing parts is a cover removably secured onto a remaining one of the housing parts;

wherein the first housing part having two flow openings: an inflow opening and an outflow opening;
a first connecting socket arranged on one of the inflow or the outflow openings of the first housing part;
a second connecting socket arranged on a remaining one of the inflow or the outflow openings of the first housing part;
a receiving space provided in an interior of the filter housing between the first and second housing openings, wherein the receiving space is configured to receive the filter element;
wherein at least one of the first housing part and the second housing part includes a support element formed as an inward projecting member projecting inwardly from an interior wall of the housing into an interior of the housing and extending towards an outflow face of the filter element to supportively engage against the outflow face of the filter element;
flow guiding elements mounted in or directly onto at least one of the first and second connecting sockets;
wherein the flow guiding elements are flow guiding baffle plates.

2. The filter housing according to claim 1 , wherein
one of the inflow and outflow openings or one of the first and second connecting sockets is arranged so as to be located at least partially outside of an area defined by projecting the filter element in a direction of a longitudinal direction of the filter element;
wherein one of the inflow and outflow openings or one of the first and second connecting sockets is arranged so as to be located at least partially outside of an area defined by laterally projecting the filter element.

3. The filter housing according to claim 1 , wherein
the first housing part is configured such that the filter element, from an inserted position in the filter housing, is guided completely along a central longitudinal direction of the filter element when removing the filter element out of the receiving area of the filter housing.

4. The filter housing according to claim 1 , wherein
the first connecting socket has a first preferred direction pointing away from the inflow opening and the second connecting socket has a second preferred direction pointing away from the outflow opening;
wherein the first and second preferred directions are positioned at an angle of greater than 0° and less than 180° relative to each other.

5. The filter housing according to claim 3 , wherein
the first connecting socket has a first preferred direction pointing away from the inflow opening and the second connecting socket has a second preferred direction pointing away from the outflow opening;
wherein the first and second preferred directions are substantially pointing in the same direction.

6. The filter housing according to claim 1 , wherein
at least one of the first and second connecting sockets comprises reinforcement elements arranged on an interior of the connecting socket, the reinforcement elements selected from the group consisting of reinforcement ribs, metal inserts, metal-reinforced sections, fiberglass-reinforced sections, and reinforcement inserts.

7. The filter housing according to claim 1 ,
wherein the flow guiding elements are flow guiding baffle plates arranged in an interior of at least one of the first and second connecting sockets.

8. The filter housing according to claim 1 , wherein
the second housing part further comprises a dust discharge opening that aligns with and abuts with the inflow opening of the first housing part.

9. The filter housing according to claim 1 , comprising
a sealing plane where the filter element, when installed, seals to the housing, separating a raw fluid area from a clean fluid area of an interior of the filter housing;
wherein at least one of the first and second housing parts comprises positioning elements arranged in an area where the sealing plane is located and configured to engage into recesses in a seal frame of the filter element to position the filter element in the filter housing.

10. The filter housing according to claim 1 , wherein
the filter element comprises a filter body and a holding frame circumferentially extending about the filter body at an inflow side of the filter element;
wherein the filter element is integrated into the first housing part or the second housing part and the holding frame has a seal that seals to the housing along a seal plane.

11. The filter housing according to claim 1 , wherein
the filter element comprises a support section at an outflow face of the filter element and
wherein at least one of the first housing part and the second housing part comprises a support element engages the support section on the outflow face of the filter element.

12. The filter housing according to claim 1 , wherein
the second housing part has a preseparating device mounted in or on one of the first and second connecting sockets or mounted in or on one of the first and second housing parts.

13. The filter housing according to claim 1 , further comprising
a third housing part arranged between the first and second housing parts and configured to receive a filter device.

14. A filter assembly comprising:
a filter housing comprising:
a first housing part; and
a second housing part;
wherein one of the housing parts is a cover removably secured onto a remaining one of the housing parts;
wherein the first housing part having two flow openings: an inflow opening and an outflow opening;
a first connecting socket arranged on the inflow opening of the first housing part;
a second connecting socket arranged on the outflow opening of the first housing part;
a receiving space provided in an interior of the filter housing between the inflow and outflow openings,

a main filter element;
wherein the receiving space is configured to receive the main filter element;
the main filter element mounted in the receiving space of the filter housing and separating a raw fluid area from a clean fluid area in the filter housing;
a cylindrical preseparator arranged within an interior of the filter housing above an inflow face of the main filter element, the cylindrical preseparator connected to the inflow opening of the first housing part;
wherein the main filter element comprises
a filter body provided with a cutout recess formed in the inflow face of the filter body;
wherein the cylindrical preseparator is accommodated at least partially within the cutout recess.

15. The filter assembly according to claim 14 , wherein
the main filter element is arranged in and detachably fastened to the second housing part of the filter housing.

16. The filter assembly according to claim 14 , wherein
the first housing part of the filter housing comprises
a dust discharge opening and
a third connecting socket arranged on the dust discharge opening.

17. The filter assembly according to claim 14 , wherein
the filter housing comprises at least one support element and the main filter element comprises a support section configured to interact with the support element.

18. The filter assembly according to claim 14 , wherein
the filter housing comprises
a sealing plane where the raw fluid area and the clean fluid area are separated from each other in an interior of the filter housing;

wherein the filter housing comprises
positioning elements in
