In order to obtain a simple, space-saving construction and in order to be used in various injection systems, a fuel injection nozzle having a nozzle needle, which is held in the closed position under the action of a spring and can be opened up by the pressure of the fuel which is to be injected, has a control piston which can be acted upon or can be relieved from pressure by means of a pressure fluid in order to transfer it into one of two different axial positions and which limits the opening travel of the nozzle needle in order to open up one or more rows of injection-nozzle holes.
