Claims
- 1. A press tool for connecting a tubular element to an element arranged in the interior and substantially adapted to the inner diameter of the tubular element, comprising:
- press jaws for generating radially directed pressure power; and
- an annular pressure distribution element arranged radially between the press jaws and the outer circumference of the tubular element, said pressure distribution element acting as an incompressible liquid and being arranged around a connecting portion of the elements to be connected, thereby distributing the pressure power generated by the press jaws substantially over the outer circumference of the tubular element.
- 2. The press tool according to claim 1, wherein said pressure distribution element is made of rubber.
- 3. The press tool according to claim 1, wherein said pressure distribution element comprises a ring filled with liquid.
- 4. The press tool according to any one of claims 1 to 3, wherein said pressure distribution element has a surface profile in contact with the connecting portion of the elements to be connected.
- 5. The press tool according to claim 1, wherein said press tool further comprises boundary elements arranged laterally next to said pressure distribution element.
- 6. The press tool according to claim 1, wherein said press tool comprises eight press jaws arranged circumferentially around said pressure distribution element.
- 7. The press tool according to claim 4, wherein said radially arranged pressure distribution element includes individual segments assigned respectively to individual press jaws.
- 8. A method for connecting a tubular element to an interior element substantially adapted to the inner diameter of the tubular element, by using the press tool of claim 1 to evenly distribute a pressure over the circumference of the tubular element, and to exert the pressure without creating areas of discontinuous pressure.
