Abstract
In a component, in particular a high-pressure part for a fuel injection system, having intersecting bores, at least one bore of the two intersecting bores is designed with a flat region, and the component has inherent compressive stresses in the area of the flat region of the bore. This yields an increase in strength of the component in the area of the intersection point of the two bores.
Claims18
A component, comprising:
- a structure including intersecting bores, wherein:
- at least a first bore of the intersecting bores includes a flat region,
- at least a second bore of the intersecting bores intersects the first bore eccentrically;
- and
- the structure includes inherent compressive stresses in an area of the flat region of the at least first bore;
- wherein an intersection of a central axis of the first bore and a central axis of the second bore is not located at a center of the component.

A component, comprising:
- a structure including intersecting bores, wherein:
- at least a first bore of the intersecting bores includes a flat region, and
- the structure includes inherent compressive stresses in an area of the flat region of the at least first bore;
- wherein the intersection bores have different diameters, and a diameter of the at least first bore is larger than diameters of remaining ones of the intersecting bores;
- wherein the diameter of the at least first bore is a multiple of a diameter of a second bore of the intersecting bores, only the at least first bore includes the flat region, and a cross section of the second bore is circular;
- and
- wherein the second bore opens eccentrically into the flat region of the at least first bore.

A method of producing a component, comprising the steps of:
- providing a structure including intersecting bores, each of the intersecting bores initially having a circular cross-section;
- and
- performing a non-cutting shaping of the structure in order to flatten at least a first one of the intersecting bores;
- wherein a second bore of the intersecting bores intersects a first bore of the intersecting bores eccentrically;
- and
- wherein an intersection of a central axis of the first bore and a central axis of the second bore is not located at a center of the component.

- performing a non-cutting shaping of the structure in order to flatten at least a first one of the intersecting bores;
- and
- prior to performing the non-cutting shaping, inserting a female die into one of the intersecting bores that is to be flattened, the female die including a recess corresponding to desired contours of a flat region at a location corresponding to a location of the flat region on the structure.
