Abstract: A distributor for a pressure atomizer includes a distributor body having an upstream end defining an internal liquid circuit, a downstream end defining a spin chamber for swirling a liquid flowing therethrough, and an outboard peripheral surface extending from the upstream end to the downstream end. The upstream and downstream ends are spaced apart along a longitudinal axis. An inclined passage is defined in the outboard peripheral surface in fluid communication with the internal liquid circuit and with the spin chamber for producing a relatively wide spray angle for a given distributor body size. The inclined passage is angled to diverge from the longitudinal axis of the distributor body in a direction toward the downstream end.

Abstract: An atomizer includes an atomizer body having a liquid inlet and a spray outlet with a liquid flow circuit defined through the inner atomizer body for fluid communication of liquid from the inlet to the spray outlet. The liquid flow circuit branches into a plurality of sub-circuits. Each sub-circuit is configured to produce a spray cone of atomized liquid issuing from the spray outlet such that the spray cone of each sub-circuit has a different cone angle. The sub-circuits are mechanically separated from one another to limit interaction of liquid in the sub-circuits and thereby produce a distinct and stable spray cone from each sub-circuit over a range of liquid flow rates.
