ABSTRACT:
A fuel injector, in particular for the direct injection of fuel into a combustion chamber of an internal combustion engine, includes a valve needle at whose discharge-side end a valve-closure member is positioned, which cooperates with a valve-seat surface, formed at a valve-seat member, to form a sealing seat. A spray-discharge orifice calotte connected to the valve-seat member of the fuel injector, or integrally formed in one piece with it, has at least three spray-discharge orifices not all extended axes of the spray-discharge orifices intersecting.
