Abstract

A holder is used for fastening a component, in particular a fuel distributor, to an internal combustion engine. The holder has at least one connection element, which includes a locating area. In the installed state, in which the connection element rests against an outer side of the component via its locating area, the locating area of the connection element extends across an angle greater than 180 degrees in relation to a longitudinal axis of the component. Furthermore, in the installed state, in which the connection element is resting via its locating area against the outer side of the component, the locating area has the form of a cylinder jacket. In addition, a system having a component and such a holder is provided.

First claim

What is claimed is:

1. A holder for fastening a component to an internal combustion engine, comprising:
a connection element having a locating area (a) that is configured to extend across an angle greater than 180 degrees in relation to a longitudinal axis of the component in the installed state and (b) via which the connection element rests against an outer side of the component in the installed state; and
a sleeve, an outer surface of which includes, at respective opposite sides of the sleeve, a first fastening area and a second fastening area, wherein:
each of the fastening areas is a respective groove in a curved surface of the sleeve;
a longitudinal extension of each of the grooves is parallel to a central longitudinal axis of the sleeve;
each of the grooves forms a respective flat surface;
a base part of a first arm of the connection element is connected to the sleeve at the first fastening area of the sleeve; and
a base part of a second arm of the connection element is connected to the sleeve at the second fastening area of the sleeve.

2. The holder as recited in claim 1 , wherein the component is a fuel distributor.

3. The holder as recited in claim 1 , wherein the connection element is configured so that, in the installed state, the locating area is at least a part of a cylindrical jacket surface or has a polygonal contour.

4. The holder as recited in claim 1 , wherein the connection element has at least one holding element that, in the installed state, is bent around the outer side of the component and makes contact with the outer side of the component.

5. The holder as recited in claim 4 , wherein the at least one holding element is flexible and is able to be connected to the component by a snap-in connection.

6. The holder as recited in claim 1 , wherein the connection element has first and second holding elements that, in the installed state, each is bent around the outer side of the component and makes contact with the outer side of the component.

7. The holder as recited in claim 6 , wherein the first and second holding elements are connected to each other in an integral fashion at with a welding seam or spot at an angular position about the longitudinal axis of the component.

8. The holder as recited in claim 6 , wherein there is a gap or slot between the first and second holding elements, in a circumferential direction relative to the longitudinal axis of the component.

9. The holder as recited in claim 1 , wherein the connection element has a deformable, annular head part which includes at least one clamping loop.

10. The holder as recited in claim 1 , further comprising a reinforcing bar extending between the first and second arms and opposite edges of which are connected to the first and second arms.

11. The holder as recited in claim 1 , wherein the connection element is configured so that the angle across which the locating area of the connection element extends in relation to the longitudinal axis of the component in the installed state is equal to 360 degrees.

12. The holder as recited in claim 1 , wherein the connection element is configured so that the angle across which the locating area of the connection element extends in relation to the longitudinal axis of the component in the installed state is less than 360 degrees.

13. A system, comprising:
a fuel distributor including a tubular base element having an outer side; and
a holder that includes:
a connection element having a locating area (a) that extends across an angle greater than 180 degrees in relation to a longitudinal axis of the fuel distributor, thereby enclosing the tubular base element by the angle greater than 180 degrees, and (b) via which the connection element rests against an outer side of the tubular base element of the fuel distributor; and
a sleeve, an outer surface of which includes, at respective opposite sides of the sleeve, a first fastening area and a second fastening area, wherein:
each of the first and second fastening areas is a respective groove in a curved surface of the sleeve;
a longitudinal extension of each of the grooves is parallel to a central longitudinal axis of the sleeve;
each of the grooves forms a respective flat surface;
a base part of a first arm of the connection element is connected to the sleeve at the first fastening area of the sleeve; and
a base part of a second arm of the connection element is connected to the sleeve at the second fastening area of the sleeve.
