Abstract

An articulated assembly for pipelines, including: two articulated sections; wherein one of the two articulated sections engages into another one of the two articulated sections; and a locking body that engages at least in areas between the articulated sections and cooperates with a locking contour on one of the articulated sections and with a locking section of the other articulated section such that a relative movement between the articulated sections is limited; wherein a guide means is provided on the articulated sections such that the two articulated sections can be joined together in a defined rotational position in relation to one another.

First claim

What is claimed is:

1. An articulated pipe joint assembly compensating for lateral movement and tilting movements, comprising:
a male articulated fluid pipe section having:
an axially extending cylindrical body having:
a first axial end;
an opposite second axial end;
an open interior extending from the first axial end to the second axial end, for conducting a fluid flow through the male articulated fluid pipe section; and
a radially outwardly projecting pin formed on an exterior of the male articulated fluid pipe section; and

a female articulated fluid pipe section having:
an inner wall circumferentially surrounding an open interior of the female articulated section;
a plurality of recesses formed in the inner wall;
a guide means arranged on a front face of the female articulated section and projecting axially outwardly away from the female articulated section, the guide means having a gap into which the radially outwardly projecting pin engages;

wherein the axially extending cylindrical body of the male articulated section is received into the open interior of the female articulated section;
a locking body installable between the male articulated section and the female articulated section, the locking body having:
a bearing ring, the bearing ring received over and surrounding the axially extending cylindrical body of the male articulated section;
a plurality of locking elements formed on a rear axial side of the bearing ring and projecting axially outwardly away from the bearing ring, the plurality of locking elements aligned to engage into the plurality of recesses of the female articulated section when the locking body is installed on the female articulated section;
wherein the locking body engages at least in areas with the male articulated fluid pipe section and with the plurality of recesses of the female articulated fluid pipe section, such that a relative movement between the articulated fluid pipe sections is limited;

wherein the pin of the male articulated section engages with the guide means, such that the male and female articulated fluid pipe sections can be joined together in a limited rotational position relative to one another.

2. The articulated pipe joint assembly according to claim 1 , wherein
the recesses are embodied at the same axial height in the female articulated fluid pipe section.

3. The articulated pipe joint assembly according to claim 1 , wherein
the guide means joins together the male and female articulated fluid pipe sections in a defined rotational position in relation to one another.

4. The articulated pipe joint assembly according to claim 1 , wherein
the bearing ring of the locking body has on an outer circumference a recessed flattened region corresponding to the guide means, the guide means of the female articulated fluid pipe section positioned in the recessed flatten region to project axially over the exterior of the locking body and bearing ring.

5. The articulated pipe joint assembly according to claim 1 , wherein
the guide means comprises a fork formed by two axially projecting flanks forming the gap therebetween, between which the radially projecting pin of the male articulated fluid pipe section can be guided.

6. The articulated pipe joint assembly according to claim 1 , wherein
the plurality of locking elements of the locking body and the plurality of recesses of the female articulated fluid pipe section engage to form a positive fit on contact.

7. The articulated pipe joint assembly according to claim 1 , wherein
the second axial end of the axially extending cylindrical body engaging in the female articulated fluid pipe section has a spherical shape.

8. The articulated pipe joint assembly according to claim 7 , wherein
the axially extending cylindrical body has on an outer surface a sealing groove at an apex of the spherical shape.

9. The articulated pipe joint assembly according to claim 8 , further comprising:
a seal ring arranged in the sealing groove and sealing between the male articulated section and the inner wall of the female articulated section.

10. The articulated pipe joint assembly according to claim 1 , wherein
the locking body has a slot such that a diameter of the locking body is reversibly expandable.

11. The articulated pipe joint assembly according to claim 1 , wherein
a thickening is provided on a radial outer surface of the axially extending cylindrical body, and an outer surface of the thickening has a spherical region which is provided in the assembled state as a locking section for cooperating with the plurality of locking elements of the locking body.

12. The articulated pipe joint assembly according to claim 1 , wherein the locking body further comprises:
a locking contour provided radially on an outside of the locking body, the locking contour adapted to fix the locking body in the assembled state into the female articulated fluid pipe section; and
a locking section provided radially on an inside of the locking body for limiting a relative movement of the male articulated fluid pipe section in relation to the the female articulated fluid pipe section.

13. A charge air pipeline for an internal combustion engine, wherein
the charge air pipeline has a first end and an opposing second end,
the charge air pipeline further comprising:
an articulated pipe joint assembly according to claim 1 , secured onto at least one of the first or second ends of the charge air pipeline.

14. A connecting pipeline with a pipe and at least one articulated pipe joint assembly according to claim 1 connected in a fixed manner to the pipe.
