ABSTRACT:
Fine liquid particles having about the same size are provided by an atomizer tip which includes a wall member having a plurality of generally triangular conduits passing through it. Forcing liquid through the conduits under pressure causes the liquid to exit the conduits as an accurately controlled, small droplet size spray pattern. The wall member is formed from a billet including a number of concentric tubes having in their surfaces a plurality of generally V-shaped longitudinal grooves filled with complementary filler material. This billet is constrictively reduced and sliced into discs, and then the discs are domed and the filler material is removed. The thickness of the discs corresponds to the desired thickness of the wall member. Due to doming, the conduits diverge outwardly. The atomizer tip is adapted for use as a spray nozzle which provides greater uniformity in droplet size. Specifically, the atomizer tip is adapted for use in a fuel injector for an internal combustion engine. The configuration of such a fuel injector is simplified in design because the atomizer tip may be mounted in support structure that requires a minimum of close tolerance parts.
