An injection nozzle for fuel injection systems of internal combustion engines is proposed, the nozzle being arranged to inject fuel into the intake tube of the engine. The injection valve includes a valve housing of ferromagnetic material, in which a tubular connection element which functions as a core and with which an armature is arranged to cooperate. Joined to the valve housing is a nozzle body having a valve seat with which a sealing section of a nozzle needle also is arranged to cooperate. The nozzle needle is guided by a plurality of guide sections in a guide bore of the nozzle body, and metering grooves are embodied on the second guide section disposed upstream of the first guide section. By metering fuel upstream of the valve seat, the fuel metering operation is prevented from being impaired by deposits.
