Abstract:
A high efficiency liquid fuel atomizer comprising:an elongated generally tubular member defining a liquid fuel pre-atomization chamber, said member having an outer wall that extends at least partially around said chamber, an upstream end adapted for connection to a source of liquid fuel and a downstream fuel delivery outlet; structure defining a generally annular pressurized atomizing fluid supply conduit disposed in surrounding relationship relative to said chamber, said structure including a conduit inlet adapted for connection to a source of pressurized atomizing fluid and a downstream pressurized atomizing fluid delivery outlet, said outer wall having at least one orifice therethrough intercommunicating said chamber and said conduit to permit pressurized atomizing fluid to enter said chamber and at least partially atomize said fluid fuel therein; and an atomizing tip including at least one mixing port arrangement that is in fluid communication with said outlets for receiving and intermixing at least partially atomized liquid fuel from said chamber and pressurized atomizing fluid from said conduit whereby to further atomize said liquid fuel.
