A structural element, primarily designed for high-pressure operation, a structural element for fuel injection systems, and a method for manufacturing it

摘要

The high pressure part (10) has intersecting bores (11,12). At least one (11) of the bores has a flat part (16). The high pressure part has internal pressure stresses in the area of the flat part. The bores are preferably a longitudinal bore and a bore that is arranged at right angles to it, where the flat part of the longitudinal bore is formed near the mouth opening of the transverse bore. An independent claim is included for a method to manufacture the part.
