Abstract (en)

[origin: WO0229242A2] The invention relates to a fuel injection valve (1), in particular, for directly injecting fuel into a combustion chamber of an internal combustion engine. Said fuel injection valve comprises an actuator (10) for actuating a valve needle (3), whereby the valve needle (3), at a spraying end, has a valve closing body (4) that, together with a valve seating (6), which is provided on a valve seat body (5), forms a tight seat. Fuel channels (35) that lead into a turbulence chamber (43) are arranged inside a valve needle guide (31), which is connected to the valve seat body (5) or provided therewith as one piece. The number of fuel channels (35) is calculated as to render a turbulent flow, which is generated in the turbulence chamber (43), homogeneous in a peripheral direction.
