Abstract (en)

[origin: WO9957433A2] The invention relates to a fuel injection valve comprising a nozzle body (300) which has a central guiding bore hole (312) and a supply channel (338) located to the side of the guiding bore hole (312). Both the bore hole and the supply channel open into a pressure chamber (334). A parting wall (346) having a smallest possible wall thickness is situated between the bore hole and the supply channel. The nozzle body (300) has a shoulder on the front end thereof, whereby the supply channel (338) projects more steeply into the pressure chamber (334), resulting in an increased wall thickness. As a result, the nozzle body (300) exhibits a greater resistance to pressure.
