ABSTRACT:
A fuel injector for fuel-injection systems of internal combustion engines includes an actuator, a valve needle, which is able to be activated by the actuator to actuate a valve-closure member, which, together with a valve-seat surface formed at a valve-seat member, forms a sealing seat; and a plurality of spray-discharge orifices which is formed in the valve-seat member. At a discharge-side end of the fuel injector, a nozzle-orifice cover is positioned, which shields the spray-discharge orifices from the combustion chamber of the internal combustion engine.
