A fuel injection nozzle is proposed with an opening needle opposed against the flow direction and in which a spring loaded abutment body is guided for longitudinal sliding movement, which body with its free end protrudes into a blind pocket reservoir of the nozzle after a successful injection. Before the beginning of the injection this blind pocket reservoir is opened to open injection holes with different injection directions branching off from the blind pocket reservoir. Through a nozzle embodiment of this kind the damaging space in the blind pocket reservoir is substantially avoided and the proportion of the unburned hydrocarbons is substantially reduced.
