Abstract
A fuel-injection nozzle for internal combustion engines having plurality of lip elements on a nozzle tube, the edges are adjacent to each other. The lip elements form an obtuse cone and are held together under a high pre-stressing pressure by a clamping sleeve and an end cap. Pressure build-up in the interior chamber of the nozzle tube elastically expands the lip edges, in which case gaps are created, which form flat spray streams through which fuel is sprayed into the combustion chamber of the engine. When the fuel pressure in the interior chamber subsides the lip edges close to prevent any dirt from entering the slits.
