Abstract

An apparatus for the injection of a fluid filler material includes a static mixer (1), with the static mixer including a housing (2) which includes a first hollow space (47), with at least one mixer element (3) being arranged in the first hollow space. The housing (2) has an outlet element (45). The outlet element (45) has a second hollow space (48), with the second hollow space (48) being connected to the first hollow space (47) such that the fluid filler material can be conducted from the first hollow space (47) into the second hollow space (48). A tubular element (60) is held in the second hollow space (48).

Claims

1. An apparatus for the injection of a fluid filler material including

a static mixer having a housing which includes a first hollow space;

at least one mixing element for mixing the fluid filler material being arranged in the first hollow space,

said housing having an outlet element having a second hollow space being connected to the first hollow space such that the fluid filler material can be conducted from the first hollow space into the second hollow space

a tubular element held in the second hollow space and characterized in that said housing is configured as a fastening element for said tubular element.

2. An apparatus in accordance with claim 1, wherein the tubular element has an outer diameter of a maximum of 3 mm.

3. An apparatus in accordance with claim 1, wherein the tubular element has a length of a maximum of 100 mm.

4. An apparatus in accordance with claim 1 wherein the outlet element includes a cone.

5. An apparatus in accordance with claim 1 wherein the second hollow space is made conically at least section-wise.

6. An apparatus in accordance with claim 1 wherein the second hollow space has an inner diameter which is smaller than the outer diameter of the tubular element.

7. An apparatus in accordance with claim 1 wherein the tubular element is one of bendable and rotatable with respect to the static mixer.

8. An apparatus in accordance with claim 7, wherein the tubular element includes at least one bending element.

9. An apparatus in accordance with claim 1 wherein the tubular element includes a jacket of metal.

10. An apparatus in accordance with claim 9, wherein the jacket of metal is covered by a plastic layer.

11. An apparatus in accordance with claim 1 wherein the tubular element includes a jacket of plastic.

12. An apparatus in accordance with claim 1 wherein the tubular element includes a core element which is arranged within the tubular element.

13. An apparatus in accordance with claim 12, wherein the core element is connected to the tubular element by means of a connection element.

14. An apparatus in accordance with claim 12 wherein the core element is surrounded at least partly by the jacket of the tubular element.

15. An apparatus in accordance with claim 1 wherein the core element is made in wire form.

16. An apparatus in accordance with claim 1 wherein the core element contains a metal.
