Abstract (en)
[origin: WO2013091963A1] The fuel injection valve (1) according to the invention for fuel injection systems of internal combustion engines has an excitable actuator (10) for actuating a valve closing body (4) which forms a sealing seat together with a valve seat surface (6) which is formed on a valve seat body (5). A plurality of ejection openings (7) are formed in the valve seat body (5) downstream of the valve seat surface (6). The fuel injection valve (1) is distinguished by the fact that the ejection openings (7) comprise at least one upstream first ejection opening section (7') and one downstream second ejection opening section (7'') with a different aperture width. Here, all the ejection opening sections (7', 7'') of the individual ejection openings (7) run coaxially with respect to the respective hole longitudinal axis (50). The ejection openings (7) are formed in a valve component which is produced as an MIM part (metal injection moulding part).
