Abstract (en)

[origin: WO2006005642A1] Disclosed is a fuel injection valve for internal combustion engines, comprising a pressure chamber (11) which is embodied in a housing (1) and in which high-pressure fuel is at least temporarily provided. A valve needle (10) which cooperates with a valve seat (36) to control a fuel flow from the pressure chamber (11) to at least two injection bores (40) is disposed in the pressure chamber (11). The injection bores (40) are provided with an inlet port (41) that is arranged in the wall of the pressure chamber (11) and an outlet port (41). The inlet ports (41) are positioned such that fuel flows from the pressure chamber (11) into the injection bores (40) when the valve needle (10) is lifted from the valve seat (36). The inlet ports (41) of at least two of the injection bores (40) located in the wall of the pressure chamber (11) are placed so as to be in contact with each other or overlap.
