Abstract

In a fuel injection nozzle that has an intermediate plate extending normal to the nozzle axis and serving in particular as an abutment for limiting the stroke of the valve needle, the aligning pins passing through separate openings in said intermediate plate are disposed in mirror symmetry with respect to a plane containing the nozzle axis. The plane defined by the pin axes is spaced from the nozzle axis. The fuel supply channel or channels which extend within the fuel injection nozzle and which pass through openings in the plate are also in mirror symmetry with respect to the first-named plane.
