Fuel injection nozzle (1) has guide boring (13) in which the nozzle needle (4) and a control piston (17) are guided, forming first control chamber (18) lying in-between. The control piston facing the first control chamber is limited on the opposite side of the second control chamber (19). A control valve (27) is provided between the second control chamber and the discharge (28). An inlet throttle (24) is provided, by which the first control chamber is connected with high pressure pipe (8). A damper throttle (25) is provided in the control piston by which the two control chambers are connected. A pre-stressing spring (23) is provided, which pre-stresses the control piston in the direction of nozzle needle.
