Abstract

A hold-down device for a fuel injection device includes at least one fuel injector and a fuel distributor line, the hold-down device being clampable between the fuel injector and the fuel distributor line, the hold-down device having a partially ring-shaped base element, from which two axially flexible hold-down clips extend, in which the partially ring-shaped base element and the two axially flexible hold-down clips are formed together by a single bent wire.

Claims (22)

1. A hold-down device for a fuel injection device, which includes at least one fuel injector and a fuel distributor line, comprising:

a partially ring-shaped base element, from which two axially flexible hold-down clips extend;

wherein the partially ring-shaped base element and the two axially flexible hold-down clips are formed together by a single bent wire, and

wherein the hold-down device is clampable between the fuel injector and the fuel distributor line, the base element being place-able onto a shoulder of the fuel injector, and the hold-down clips being place-able into contact with the fuel distributor line.

2. The hold-down device of claim 1 , wherein the hold-down clips each have at least one web, an oblique segment and a contact segment.

3. The hold-down device of claim 2 , wherein the two contact segments of the hold-down clip terminate it, so that the hold-down device is open.

4. The hold-down device of claim 1 , wherein the bent wire is a square-shaped wire.

5. The hold-down device of claim 1 , wherein the bent wire has a cross-sectional area of 1 square millimeter to 9 square millimeters.

6. The hold-down device of claim 1 , wherein the bent wire is made from at least one of: stainless steel, spring steel, or 1.4310 high-grade steel.

7. The hold-down device of claim 1 , wherein, in a top view of hold-down device, at least one of the hold-down clips is covered by the partially ring-shaped base element and/or covers the partially ring-shaped base element at least partially.

8. The hold-down device of claim 1 , wherein the bent wire is a square-shaped wire having a square cross section.

9. The hold-down device of claim 1 , wherein the bent wire has a cross-sectional area of between 1 and 9 square millimeters.

10. The hold-down device of claim 1 , wherein the base element lies in a base plane, and each of the hold-down clips includes a section extending perpendicular to the base plane.

11. The hold-down device of claim 10 , wherein each of the hold-down clips includes a second section extending at an angle from the section extending perpendicular to the base plane.

12. The hold-down device of claim 1 , wherein each of the hold-down clips includes a contact segment pointing in a direction opposite to an opening in the base element.

13. The hold-down device of claim 1 , wherein the base element includes at least a semi circular ring shape portion.

14. The hold-down device of claim 1 , wherein the base element includes at least 210° of a circular arc.

15. The hold-down device of claim 1 , wherein the base element lies in a base plane, the wire includes a square cross section, first straight sides of the cross section are parallel with the base plane, and second straight sides of the cross section are perpendicular to the base plane.

16. The hold down-device of claim 1 , wherein each of the hold-down clips has a web segment connected to the base element via a fillet and an oblique segment connected to the web segment via a fillet.

17. The hold-down device of claim 16 , wherein the oblique segment is curved.

18. The hold down-device of claim 16 , wherein each of the hold-down clips has a contact segment connected to the oblique segment via a fillet.

19. The hold-down device of claim 16 , wherein the contact segment is curved.
