ABSTRACT:
A fuel injection valve for internal combustion engines. The valve includes a nozzle needle longitudinally displaceably guided in a nozzle body and having a tensioning nut which axially braces the nozzle body with a nozzle holder, optionally, by way of a transition piece whose respective faces rest on an adjacent face. The valve also includes at least one feed pipe extending in the nozzle holder and the nozzle body, and fuel-carrying transfer points between the nozzle holder and the nozzle body. A portion of at least one of interacting faces (3a; 4a) being constructed as a raised contact surface (11) with surface elements surrounding the fuel-carrying transfer points.
