FUEL INJECTION VALVE AND METHOD FOR SHAPING DISCHARGE PORTS |
摘要 |
<p>A fuel injector for fuel injection systems of internal combustion engines has an excitable actuator for activating a valve closing element, which forms a sealing seat together with a valve face implemented on a valve seat element. Multiple spray-discharge openings are implemented in the valve seat element downstream from the valve face. The fuel injector is distinguished in that the spray-discharge openings include at least one upstream first spray-discharge opening section and one downstream second spray-discharge opening section having a different opening width and a wall area of the second spray-discharge opening section of all spray-discharge openings on a semi-circle runs either parallel or at a right angle to the longitudinal axis of the valve seat element having the spray-discharge openings. The valve seat element is manufactured using metal injection molding methods.</p> |
