Abstract
A flow-restricted compound spray generating device 100 includes a spray face member 120B including at least one fluidic circuit oscillator defining geometry 132 including an outlet orifice 138 in the spray face member's central area configured to aim an oscillating spray 300 having a selected oscillating spray thickness distally along a spray axis 112. The spray face member 120B also includes a plurality of non-oscillating (e.g., laminar or jet) spray generating orifices 160B arrayed evenly around the spray face member's periphery to aim a plurality of non-oscillating laminar or jet sprays 302 distally along the spray axis 112 to provide a ring of high velocity streams arrayed around the central oscillating spray 300 to generate a compound spray 310 with an outflow which has a pleasing spray density with an apparent outflow thickness which is substantially equal to the spout orifice's diameter 320.
