Abstract (en)

[origin: WO0250427A1] The invention relates to a fuel injection valve (1), especially for the direct injection of fuel into the combustion chamber of a mixture-compressing, spark-ignited internal combustion engine. Said valve comprises an actuator (10), a valve needle (3), actuated by the actuator (10), for actuating a valve closing body (4) that forms a sealing seat together with a valve face (6), and a swirl plate (34) that has at least one swirl duct (36). An elastic membrane (37) is disposed on the inlet side of the swirl plate (34) in such a manner that a metering cross-section of the at least one swirl duct (36) can be varied depending on the fuel pressure prevailing in the fuel injection valve (1) during operation.
