Abstract
This invention discloses fuel injection nozzles for internal combustion engines which are known to have a needle valve that is shiftable under pressure of the fuel supply against the force of a closing spring and more particularly the improvement wherein the opening stroke of the needle valve can be changed by a transversely movable slide element that includes a spool-like body having a medial area of varying diameter which serves to limit the stroke of the needle valve.
