ABSTRACT:
An electromagnetically actuated fuel injector is provided with a discharge region of improved construction. The injector discharge region includes a central flow axis and, sequentially in the downstream direction, a simple metering orifice symmetrical with the axis, and flow patterning structure including a diverging flow director for directing the flow of fuel issuing from the metering orifice radially outward relative to the axis to an annular region about the axis and a converging flow director for directing the fuel radially inward relative to the axis from a position radially outward thereof for direct "transparent" discharge thereafter from the injector. A discrete exit nozzle may be shaped to effect the requisite flow convergence, and the angle of that convergence affects the geometry of the final spray pattern. A swirl disc may be positioned intermediate the other two flow directors. By preselecting the angle at which channels in the swirl disc are skewed to the axis, it is possible to obtain respective ones of a variety of fuel spray patterns ranging from a wide angle hollow cone for an acute angle of tangentiality to a string of fuel droplets substantially along the axis when the swirl channels are substantially parallel the axis. The uppper and lower ends of the swirl disc may be tapered.
