Fuel injection valve for internal combustion engine, has valve body, in which pressure chamber is formed, where sharp-edged orifice is fastened on valve needle with outer area
摘要
<p>The fuel injection valve has a valve body (2), in which a pressure chamber (15) is formed. A valve needle (19) is arranged in the pressure chamber in longitudinally displaced manner. A sharp-edged orifice (45) is fastened on the valve needle with an outer area. The outer area is spaced from inner side of the pressure chamber so that a sharp-edged gap throttle is formed by an edge of the sharp-edged orifice and inner side of the pressure chamber. An independent claim is also included for a method for manufacturing fuel injection valve for internal combustion engine with a valve body.</p>
