Abstract
A fuel injection nozzle or fuel injector valve has a nozzle body, extending along a longitudinal axis, on which is configured a valve seat surface which coacts with a valve closure surface configured on a valve closure element to form a valve seat. At least one fuel stream, which has a radial directional component with respect to the longitudinal axis of the nozzle body, is sprayed out when the fuel injection valve or fuel injector nozzle is in an open state. A sleeve body axially overlaps the fuel stream in the direction of the longitudinal axis. The sleeve body has at least one impact surface which the fuel stream strikes. The impact surface is inclined at a predefined angle with respect to a vertical plane which runs vertically with respect to the longitudinal axis, and/or the impact surface is structured in fluted fashion on its surface.
