ABSTRACT:
A fuel injection nozzle for internal combustion engines having a nozzle body, firmly fastened to a nozzle holder with an interposition of a shim, and a valve needle that is axially displaceable in the nozzle body and that is lifted by the fuel pressure, counter to a closing spring assembly for the injection of fuel. To lend the injection nozzle a slender form, the chamber receiving the closing spring assembly is disposed eccentrically to the nozzle axle and the fuel inlet conduit in the nozzle holder, specifically in the portion of the nozzle holder wall that is thicker as a result of the eccentricity. In order, moreover to transmit the closing force of the closing spring assembly to the valve needle without shear forces as much as possible, a pressure protrusion that transmits the closing force is guided in an aperture extending eccentrically to the nozzle axle (b). The protrusion is integrally joined with an adapter or with the valve needle.
