<p>A fuel injector, which has a valve-seat body with a fixed valve-seat surface, a valve-closure member cooperating with the valve seat for the opening and closing of the valve. The valve-seat body is accommodated in a longitudinal opening of a valve-seat support and fixedly joined thereto. An atomizer front piece is galvanically premolded directly on a lower end face of the valve-seat body in an adhesive manner. At least one spray-discharge orifice is provided in the atomizer front piece, which preferably widens in a funnel shape in the downstream direction. The fuel injector is particularly suitable for use in fuel-injection systems of mixture-compressing internal combustion engines having externally supplied ignition.</p> |
