A valve assembly including a block forming a bore. An air inlet opening is in communication with the bore, and provides a volume of air into the bore. The bore provides communication between the air inlet opening and at least one air outlet passage. A fuel inlet opening is in communication with the bore, and provides a volume of fuel into the bore. The bore provides communication between the fuel inlet opening and at least one fuel outlet passage. A pintle is slidably positionable within the bore to control the volume of air directed out of the bore through the air outlet passage and the volume of fuel directed out of the bore through the fuel outlet passage.

What is claimed is: 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. 2. The valve assembly of claim 1 further comprising an air metering tube positioned within each of the at least one air inlet openings, and metering the volume of air directed into the mixing chamber. 3. The valve assembly of claim 1 further comprising a fuel injector device positioned within the fuel inlet opening and providing communication between the fuel inlet line and the mixing chamber. 4. The valve assembly of claim 1 wherein the volume of air is discharged tangentially into the mixing chamber through the air inlet opening. 5. The valve assembly of claim 1 further comprising a diffuser selected from the group consisting of square, circular, oblong, rectangular and combinations thereof, wherein the diffuser includes crimping, ribbing or slotted opening for creation of a centripetal vortex or a braided helix. 6. The valve assembly of claim 1 wherein the centripetal vortex forms a helix. 7. 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 tangential component and an axial component formed 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 substantially 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 having at least one centripetal vortex into the outlet passage; an air metering tube positioned within each of the at least one air inlet openings, and metering the volume of air directed into the mixing chamber; and an ignitor operatively connected to the burner to ignite the air:fuel mixture. 8. The valve assembly of claim 7 further comprising a burner connected to the at least one outlet passage. 9. The valve assembly of claim 7 further comprising an ignitor operatively connected to the burner to ignite the air:fuel mixture. 10. The valve assembly of claim 7 wherein each air inlet opening forms a different angle of incidence with the mixing chamber and each angle of incidence varies from the other angle of incidence by approximately 10°. 11. The valve assembly of claim 10 wherein the angle of incidence of one air inlet opening is approximately 42° and the angle of incidence of the other air inlet opening is approximately 50°.
