Abstract
Fuel injection valve is described which possesses a multilayer swirl valve downstream from a valve seat shaped onto a valve seat element, at least these two components being installed from the inflow direction into a passthrough opening of a valve seat support. The valve seat support has a lower base region that provides for a reduction in the cross section of the passthrough opening downstream from the valve seat. The fuel injection valve is suitable in particular for direct injection of fuel into a combustion chamber of a mixture-compressing, spark-ignited internal combustion engine.
