Nozzle assembly for diesel fuel injection valve in internal combustion engine, has nozzle pin which in closed position, prevents fluid flow through injecting hole and releases fluid flow through injecting hole in other positions

摘要

The assembly has coatings (20,21) arranged relative to a center line of a nozzle body and within a closing area of the body. The coatings are provided radially outside/inside to an orifice of an injecting hole, where the coatings couple a nozzle pin (5) with the body. The pin in its closed position, prevents the fluid flow through the injecting hole and the releases the fluid flow through the injecting hole in other positions. An independent claim is also included for an injection valve comprising a nozzle assembly.
