Method for machining the edge of the bore of the branch connection of a common fuel line and the common fuel line thus manufactured

摘要

The present invention relates to a method for machining the edge of a radial bore 21 of a connection 2 for branching of an injection nozzle with an axial chamber 11 of a common fuel line 100 of an injection system of an internal combustion engine and, according to this method, the passage of the radial bore 21 into the chamber 11 of the common fuel line is deburred. A connecting rim 3 is produced in the form of a rotating surface 3S along the axis ZZ of the bore 21 , this connecting rim having a surface 11S of the axial chamber 11 and a radial bore 21 . The edge 22 of the passage of the radial bore 21 to the axial chamber 11, protruding from the surface 21S of the
