ABSTRACT:
A fuel injector for fuel injection systems of internal combustion engines having a magnetic coil, a valve needle, which is in operative connection with the magnetic coil and acted upon in a closing direction by a restoring spring to actuate a valve-closure member, which, together with a valve-seat surface formed at a valve-seat member, forms a sealing seat; and having at least one spray-discharge orifice which is formed in the valve-seat member. The spray-discharge orifices discharge from elevations which project beyond an outer end face of the valve-seat member, the fuel being guided through flow channels in the elevations.
