Abstract

A multi-orifice injector nozzle in which a main channel is bifurcated into two slanting intermediate channels which are again bifurcated, the resulting outer branches leading to outer nozzle inserts, while the inner branches are joined above a central nozzle insert. All channels are obtained as smoothly curved congruent grooves milled into the clamping faces of a split injector head.
