Abstract
A high efficiency liquid fuel atomizer includes an elongated generally tubular member defining a liquid fuel pre-atomization chamber. The tubular member has an outer wall that extends around the chamber, an upstream end adapted for connection to a source of liquid fuel and a downstream fuel delivery outlet. The atomizer also includes a larger diameter outer tube that is concentric to the tubular member and defines a generally annular pressurized atomizing fluid supply conduit disposed in surrounding relationship relative to the chamber. The outer tube has an inlet adapted for connection to a source of pressurized atomizing fluid and a downstream pressurized atomizing fluid delivery outlet. One or more orifices are provided in the outer wall of the tubular member so as to intercommunicate the chamber and the annular conduit to permit pressurized atomizing fluid to enter the chamber and at least partially atomize the fluid fuel therein. Also disclosed is an atomizing tip which includes a novel y-shaped for further atomizing the liquid fuel.
