| 摘要 |
A fuel injector for fuel injection systems of internal combustion engines has an energizable actuator for actuating a valve-closure member, which, together with a valve seat face configured on a valve seat body, forms a sealing seat. Downstream of the valve seat face, a plurality of spray-discharge orifices are formed, which include one upstream, first spray-discharge orifice section and one downstream, second spray-discharge orifice section having different orifice widths. The orifice sections of the individual spray-discharge orifices extend coaxially to the particular longitudinal bore axis. The spray-discharge orifices are formed in a valve component manufactured as a metal injection molding part. |
