Abstract
A fuel inject includes an orifice plate which is arranged on a valve-seat member, particularly at its downstream end face, the valve-seat member having a fixed valve seat, the orifice geometry of the orifice plate being bounded by the valve-seat member, so that the flow ratios in the orifice plate are influenced by the valve-seat member. The valve-seat member covers an upper inlet region of the orifice plate, at least to the extent that downstream outlet orifices of the orifice plate are overlapped. The fuel injector is particularly suited for use in fuel systems of mixture-compressing internal combustion engines with externally supplied ignition.
