ABSTRACT:
A fuel injection valve for internal combustion engines, has a valve body with a pressure chamber that can be filled with fuel under pressure. Embodied in the valve body is at least one injection conduit, which originates at the wall of the pressure chamber, where it forms an injection opening; the injection conduit connects the pressure chamber with the combustion chamber of the engine. By means of a valve needle, the injection opening can be closed or opened. The injection opening of the injection conduit has a cross section in the form of an oblong slot, so that the injection of the fuel into the combustion chamber is optimized.
