Impinging sheet atomizer nozzle

A pressure atomizer includes a body having a central axis, and defining a chamber. The body further defines a connecting passage that fluidly connects the chamber to an exterior of the body. The connecting passage has an inside surface. A substantially cylindrical separator collar is disposed concentrically within the connecting passage, and includes an inside surface and an outside surface. At least a portion of the outside surface is disposed a predetermined distance from the inside surface of the connecting passage to thereby define an outer fluid passageway. The outer fluid passageway extends from the chamber to a first exit point. A pintle is disposed substantially concentrically within the separator collar. The pintle includes an outside surface that is disposed a predetermined distance from the inside surface of the separator collar to thereby define an inner fluid passageway. The inner fluid passageway extends from the chamber to a second exit point.
