Fuel injection system for internal combustion engines, especially a pump nozzle in which the relief duct 41 of the pump working chamber 15 is controlled by a solenoid valve 43 to 49, which is arranged coaxially with the pump piston 11 around the pump cylinder 14. This annular solenoid valve controls at least two relief duct orifices 42 and can be divided into a plurality of small magnetic circuits, the total magnetic force of which suffices for the required actuating power. <IMAGE>
