Abstract

An air cleaner of an internal combustion engine has a housing with a slide-in opening and receives a slide-in filter element through this opening. A cover element closes off the slide-in opening. The cover element has a snap element for fixing the cover element at the housing. The cover element has a contact face defining a first main plane. A sealing is disposed between the filter element and the housing and seals between filter element and housing. A sealing face provided at the housing interacts with the sealing and defines a second main plane. The housing has a contact face abutting the contact face of the cover element in the closing state of the cover element. An angle between the second main plane of the sealing face of the housing and the first main plane of the contact face of the cover element is different from 90°.

First claim

What is claimed is:

1. An air cleaner of an internal combustion engine, the air cleaner comprising:
a housing comprising:
a first housing part having an air inlet port, the first housing part defining and inlet chamber therein;
a second housing part having an outlet port for filter air, the second housing part defining an outlet chamber therein;
wherein the second housing part is closed upon and affixed onto the first housing part such that the outlet chamber and inlet chamber are joined to form a housing interior chamber enclosed within the first and second housing parts;
wherein the housing has a slide in opening in a first lateral sidewall of the housing, the slide-in opening, opening into the housing interior chamber arranged between the first and second housing parts;
at least one snap face provided on the housing proximate to the slide-in opening;

a removable drawer member slideably insertable into and slideably removable from the housing though the slide-in opening, the removable drawer member including:
a drawer frame configured to receive and support a filter element therein, wherein, when in an inserted and locked state of the draw member, the drawer frame extending across the housing interior chamber between the first lateral wall and an opposing second lateral wall of the housing;
a cover element arranged on a first lateral end of the drawer frame, the cover element sized and configured to close off the slide-in opening of the housing when in the inserted and locked state of the draw member;
the cover element forming a common plate spaced outwardly away from an outer surface of the cover element, the common plate flexibly moveable on the cover element relative to the housing, the comment plate formed together with the cover element as unitary component;
at least one snap element arranged on the common plate and lockably engaging with respective ones of the at least one snap face of the housing, locking the drawer member into the locked state in the housing interior chamber of the housing.

2. The air cleaner of an internal combustion engine according to claim 1 , wherein
the cover element has a contact face defining a first main plane;
a sealing disposed between the filter element and the housing and adapted to seal between the filter element and the housing;
a sealing face provided at the housing and adapted to interact with the sealing, wherein the sealing face defines a second main plane;
wherein the housing has a contact face abutting the contact face of the cover element in the closing state of the cover element;
wherein a first angle between the second main plane of the sealing face of the housing and the first main plane of the contact face of the cover element is different from 90 degrees.

3. The air cleaner according to claim 2 , wherein
a tension force of the at least one snap element generates a first force component and a second force component,
wherein the first force component is perpendicular to the first main plane of the contact face of the cover element and
wherein the second force component is perpendicular to the second main plane of the sealing face of the housing.

4. The air cleaner according to claim 3 , wherein
a second angle between a direction of the tension force of the at least one snap element and the first main plane of the contact face of the cover element is different from 90 degrees.

5. The air cleaner according to claim 4 , wherein
the second angle is between 20 degrees and 70 degrees.

6. The air cleaner according to claim 5 , wherein
the second angle is approximately 45 degrees.

7. The air cleaner according to claim 4 , wherein
a third angle between the direction of the tension force of the at least one snap element and the second main plane of the sealing face of the housing is approximately 90 degrees.

8. The air cleaner according to claim 2 , further comprising
a sealing element arranged between the contact face of the housing and the cover element.

9. The air cleaner according to claim 2 , wherein
the slide-in opening is arranged on a raw-gas side of the filter element.

10. The air cleaner according to claim 2 ,
wherein at least one counter support is arranged on an end of the cover element opposite the at least one snap element is adapted to connect said end of the cover element to the housing at an opposite side of the slide-in opening relative to the at least one snap face.

11. A filter element comprising
a pleated filter medium and a circumferential elastic sealing,
wherein the filter element is adapted to be inserted into a removable drawer member of an air cleaner according to claim 2 .

12. The air cleaner according to claim 1 , wherein
the cover element is formed in one piece together with drawer frame as a single unitary component.
