Consumption optimized nozzle assembly

A nozzle assembly for delivering media to a surface, comprising:

• a spray element comprising an outlet and an eductor adapted for directing a dual-media jet through the outlet, the eductor comprising a mixing barrel that extends along an axis between the outlet and a diffusion portion that comprises an injection port disposed about a central intake duct;
• an active conduit adapted for directing a pressurized stream of a first media into the eductor of the spray element, the active conduit comprising an inlet for receiving the first media and a pair of constricted channels that each extend between the inlet and the injection port of the spray element;
• and
• a passive conduit adapted for passage of a second media into the eductor of the spray element, the passive conduit comprising an intake for receiving a passive feed of the second media and a feed shaft that extends between the intake and the central intake duct of the spray element between the pair of constricted channels of the active conduit.
