ABSTRACT:
A fuel injection nozzle for internal combustion engines which includes a blind bore disposed transversely to the axis of the nozzle, in which bore is provided an adjustment mechanism for exteriorly varying the pre-loaded tension of a closing spring acting on the needle valve of the fuel injection nozzle. Plural embodiments disclose that variance in the spring loading is achieved by rotating the adjustment mechanism through different positions to urge the spring downwardly against a cap retaining the spring. The adjustment mechanism is sealed against fuel leakage from the bore and retained therein by the force of the spring plate on a surface cooperative therewith.
