Abstract:
1. A valve assembly comprising: a block defining a mixing chamber, wherein the block forms two opposing angled surfaces; an air inlet line positioned with respect to the block; a pair of air inlet openings formed in the block and in communication with the air inlet line and the mixing chamber, the pair of air inlet openings each having a tangential component and an axial component relative to the mixing chamber to provide a volume of air into the mixing chamber to create an air flow path within the mixing chamber that includes at least one centripetal vortex and the pair of air inlet openings each project in planes perpendicular to each other, wherein the pair of air inlet openings is formed in each angled surface of the opposing angled surfaces, the pair of air inlet openings extending into the mixing chamber and at an angle relative to sidewalls of the mixing chamber; a fuel inlet opening formed in the block, wherein the fuel inlet opening is co-axial with and in communication with the mixing chamber; an axial fuel inlet line positionable with respect to the fuel inlet opening and providing a volume of fuel into the mixing chamber; and at least one outlet passage in communication with the mixing chamber, an air:fuel mixture exiting the mixing chamber into the outlet passage, wherein the air:fuel mixture exits the outlet passage in a flow path having at least one centripetal vortex.
