Definitions
- valve seat 8 a plurality of injection openings 15 are formed, which open into the combustion chamber of the internal combustion engine when the fuel injection valve is installed in a corresponding internal combustion engine.
- the valve needle 7 cooperates with its sealing surface 9 with the valve seat 8 in such a way that upon contact of the valve needle 7 on the valve seat 8, the pressure chamber 11 is separated from the injection ports 15, while lifted from the valve seat 8 valve needle 7, a fuel flow from the Pressure chamber 11 to the injection openings 15 instead- - A -
