Abstract
A fuel injection nozzle for internal combustion engines having an inwardly opening valve needle is proposed, this valve needle has a channel comprising two parts, the first of which located in the upstream direction, has a smaller measurement in cross section in one dimension than the diameter of the communicating or downstream part which has the exact injection diameter. As a result, the entry of shavings into the downstream part and the consequent alteration in injection are avoided.
