Abstract

A fuel injection nozzle for internal combustion engines with a nozzle needle movably guided in a nozzle body, which supplies fuel metered by a metering device under pressure to the combustion space by way of at least one injection bore; a servo-piston is thereby provided on the actuating side of the nozzle needle which is guided intermittently actuatable and displaceable against the force of a spring in the injection direction by a pressure medium.
