Abstract
An injection valve, particularly for injecting fuel directly into a combustion chamber of an internal combustion engine, has a flow path whose end region encompasses an annular gap on the outlet side, and which, in the open state, has at least one annular injection opening that is provided on the outlet side in a closing part, downstream of the annular gap with respect to the flow direction. To achieve good fuel distribution during injection, particularly in a combustion chamber of an internal combustion engine, and to be able to set the penetration of the fuel stream into the combustion chamber, means are associated with the annular gap that determine the cross section of the flow path establishing the flow volume such that this cross section has varying radial widths in a circumferential direction of the annular gap.
