Abstract

The invention relates to a coupling arrangement ( 10 ) for pipelines, with a female coupling section ( 20 ) and a male coupling section ( 40 ) as well as a locking element ( 60 ) which at least in regions engages between the coupling sections ( 20, 40 ) and is secured on a coupling section ( 20 ), one of the coupling sections ( 20 ) comprising a locking contour ( 34 ) which cooperates with a locking contour ( 64 ) of the locking element ( 60 ), and the locking element ( 60 ) having a blocking section ( 62 ) which cooperates with a blocking section ( 52 ) of the other coupling section ( 40 ) such that a lateral movement between the coupling sections ( 20, 40 ) can be restricted.

First claim

1 . A coupling arrangement ( 10 ) for pipelines adapted to compensate for lateral movement and tilting movements between connection points, comprising:
a female coupling section ( 20 ); and a male coupling section ( 40 ); a locking element ( 60 ) which is arranged between and engages between the coupling sections ( 20 , 40 ) and is secured on one of the coupling sections ( 20 ); the locking section comprising:
a locking contour ( 34 ) which cooperates with a locking contour ( 64 ) of the locking element ( 60 );
wherein the locking element ( 60 ) has a blocking section ( 62 ) which cooperates with a blocking section ( 52 ) of the other coupling section ( 40 ) such that a lateral movement between the coupling sections ( 20 , 40 ) can be restricted.

2 . The coupling arrangement according to claim 1 , wherein
the locking contour ( 64 ) of the locking element ( 60 ) is arranged in a region which engages between the coupling sections ( 20 , 40 ).

3 . The coupling arrangement according to claim 1 , wherein
the blocking section ( 62 ) of the locking element ( 60 ) and the blocking section ( 52 ) of the coupling section ( 40 ) form a positive-locking fit upon contact.

4 . The coupling arrangement according to claim 1 , wherein
the locking element ( 60 ) is formed as a wedge ring with a bearing surface ( 66 ) on a face side ( 26 ) of the female coupling section ( 20 ) and a collar ( 68 ) which engages between the coupling sections ( 20 , 40 ).

5 . The coupling arrangement according to claim 1 , wherein
a diameter of the locking element ( 60 ) is reversibly expandable for an intended assembly of the coupling sections.

6 . The coupling arrangement according to claim 1 , wherein
the blocking section ( 52 ) at the coupling section forms a region ( 50 ) of an outer surface ( 48 ) of a thickening ( 44 ) at the face side of the male coupling section ( 40 ).

7 . The coupling arrangement according to claim 6 , wherein
the blocking section ( 52 ) at the coupling section is formed to be crowned at least in certain regions.

8 . The coupling arrangement according to claim 1 , wherein
the locking contour ( 34 ) of the female coupling section ( 20 ) is arranged on an inner side ( 28 ) of the female coupling section ( 20 ).

9 . The coupling arrangement according to claim 1 , wherein
the locking contours ( 34 , 64 ) are formed as a bayonet connection.

10 . The coupling arrangement according to claim 1 , wherein
the locking contours ( 34 , 64 ) are formed as latching connections.

11 . The coupling arrangement according to claim 1 , wherein
the male coupling section forms a joint ball; wherein the female coupling section forms a ball socket into which the joint ball is slidably and tiltably received; wherein the locking element engages against the male coupling section and the female coupling section to enable and limit lateral movement of the male couple section relative to the female coupling section; wherein the locking element engages against the male coupling section and the female coupling section to enable and limit angular tilting movement of the male couple section relative to the female coupling section.

12 . A use of the coupling arrangement according to any one of claims 1 for establishing a quasi-rigid connection of charge air pipes for an engine.

13 . A coupling section ( 20 ) for a coupling arrangement ( 10 ) according to claim 1 , wherein
on an inner side ( 28 ) in a receiving region ( 32 ) for at least one locking contour ( 64 ) of a locking element ( 60 ) at least one locking contour ( 34 ) is provided.

14 . A coupling section ( 40 ) for a coupling arrangement ( 10 ) according to claim 1 , wherein
a thickening ( 44 ) is provided at a face-side end ( 46 ) of the coupling section; wherein an outer surface ( 48 ) of the thickening has a region ( 50 ) that is provided as a blocking section ( 52 ) in an assembled state for cooperating with a blocking section ( 62 ) of a locking element ( 60 ).

15 . A locking element ( 60 ) for a coupling arrangement ( 10 ) according to claim 1 , wherein
a locking contour ( 64 ) is provided radially on an outside of the locking element and is operative for securing the locking element ( 60 ) in an assembled state onto a first coupling section ( 20 ); and a blocking section ( 62 ) is arranged radially on an inside of the locking element for restricting a lateral movement of a second coupling section ( 40 ).

16 . A pipeline ( 110 ) adapted to compensate for lateral movement and tilting movements between connection points, comprising:
a coupling arrangement ( 10 ) for pipelines, comprising:
a female coupling section ( 20 ); and

a locking contour ( 34 ) which cooperates with a locking contour ( 64 ) of the locking element ( 60 );
wherein the locking element ( 60 ) has a blocking section ( 62 ) which cooperates with a blocking section ( 52 ) of the other coupling section ( 40 ) such that a lateral movement between the coupling sections ( 20 , 40 ) can be restricted;

wherein at least one of the coupling sections ( 40 ) has a thickening ( 44 ) at a face-side end ( 46 );
wherein an outer surface ( 48 ) of the thickening ( 44 ) has a region ( 50 ) which, in an assembled state, is arranged as a blocking section ( 52 ) cooperating with a blocking section ( 62 ) of a locking element ( 60 ).
