Abstract: A fluid injector includes a fluid inlet; a valve seat located downstream of the fluid inlet and having a valve seat aperture extending therethrough; a valve member moveable between a closed position and an open position to control flow through the valve seat aperture; and director plate including a first aperture and a second aperture extending therethrough. A fluid flow channel is formed between the valve seat and the director plate and extends from an inlet end to an outlet end. The first aperture and the second aperture extend through the director plate from the fluid flow channel. The first aperture is located between the inlet end and the second aperture. The fluid flow channel decreases in cross-sectional area from the inlet end toward the first aperture and the fluid flow channel increases in cross-sectional area from the first aperture toward the second aperture.

Abstract: 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.
