Abstract (en)
[origin: WO2005068824A1] The fuel injection valve comprises at least one valve body (1) wherein a piston-shaped valve needle (5) is arranged in a bore (3), cooperating with a valve seat (7). A throttle bundle (34) is embodied on the valve needle (5) and is arranged in a throttle section (36) when the valve needle (5) rests on the valve seat (7). When the valve needle (4) is opened in a lifting movement, said throttle bundle emerges from the throttle section (36), whereupon a flow cross-section (14) is controlled in such a way that fuel can flow between the valve needle (5) and the wall of the bore (3) to the injector openings (11). A fuel channel (42), which is formed in the valve needle, is provided with at least one inlet (43) located downstream from the throttle bundle (34) and an outlet (48), enabling fuel to be also supplied to the injector openings (11) via the fuel channel (42).
