A fuel injection valve is described which has a swirl disk downstream from a valve seat, the swirl disk being made of at least one metallic material, having at least two swirl channels opening into a swirl chamber, and in which all layers are adheringly deposited directly one on top of the other by electroplating (multilayer electroplating). The swirl disk is installed in the valve so that the surface normal to its surface forms an oblique angle other than 0&deg; with the longitudinal valve axis, so that a jet angle &ggr; with respect to the longitudinal valve axis is formed due to the orientation of the swirl disk. The fuel injection valve is particularly well suited for direct injection of fuel into the combustion chamber of a compressed mixture externally ignited internal combustion engine.

Fuel injection valve

A fuel injection valve has a deflection surface which has at least one depression, with the aid of which precisely aligned single, twin or multiple fuel jets can be generated, it being possible to achieve different fuel jet shapes by means of the configuration of the at least one depression. The fuel injection valve is intended, in particular, for mixture-compressing, applied-ignition internal combustion engines.

A fuel injection valve includes a valve-closure member which is provided with semicircular flattenings. The deflecting surfaces delimiting the flattenings and formed obliquely to the longitudinal valve axis cause a rotational energy to be applied to the fuel. The application of rotational energy to the fuel makes it possible to clearly reduce the change in flow rate caused by the rotational position of the needle, so that the variance in the static flow rate is considerably decreased. The valve is particularly suitable for application in fuel injection systems of mixture-compressing internal combustion engines having externally supplied ignition.
