Abstract
Abstract A housing having an air inlet and an exhaust is divided into a central plenum and a combustion chamber by a porous member. A rotatable shaft passing through the plenum is driven by a motor, and drives a fuel pump, a blower and an atomizer/vaporizer. Fuel is pumped to the atomizer/vaporizer where it is forced outwardly by the rotation through porous walls into a scroll where it is mixed with the air introduced by the blower. The scroll converts the velocity of the mixture into a pressure head so that upon entering the plenum it passes through the porous member. It burns on the surface of the porous member in the combustion chamber, heating and vaporizing fluid carried in a tube in the combustion chamber.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
In a vapor generator having a central plenum formed by a porous member for receiving a combustible mixture, an improved carburetion system comprising: a rotatable member having secured thereto for rotation with it: a liquid fuel pump, a blower, and a fuel atomizer/vaporizer; means for rotating said rotatable member; conveying means for delivering to said fuel atoMizer/vaporizer fuel pumped by said liquid fuel pump; said fuel atomizer/vaporizer directing atomized and/or vaporized fuel outwardly; said blower positioned to mix said atomized and/or vaporized fuel with air and blow the mixture into said plenum; and scroll means for converting the velocity of the mixture caused by said blower to a pressure head.
Claim 2
Dependent Claim
110 words
In a vapor generator having a central plenum formed by a porous member for receiving a combustible mixture, an improved carburetion system comprising: a rotatable member having secured thereto for rotation with it: a liquid fuel pump, a blower, and a fuel atomizer/vaporizer; means for rotating said rotatable member; conveying means for delivering to said fuel atoMizer/vaporizer fuel pumped by said liquid fuel pump; said fuel atomizer/vaporizer directing atomized and/or vaporized fuel outwardly; said blower positioned to mix said atomized and/or vaporized fuel with air and blow the mixture into said plenum; and scroll means for converting the velocity of the mixture caused by said blower to a pressure head.
Claim 3
Dependent Claim
20 words
A vapor generator according to claim 1 wherein: said scroll means in two stages with a blower in each stage.
Claim 4
Dependent Claim
130 words
A vapor generator comprising: a housing having an air inlet and an exhaust; a porous member dividing said housing into a central plenum and a combustion chamber; a blower positioned to move air through said inlet; a fuel pump; a fuel atomizer/vaporizer; means for conveying fuel from said fuel pump to said antomizer/vaporizer; means for rotating said fuel pump and said blower at the same speeds; means for mixing said atomized/vaporized fuel with said air to form a combustible mixture; said means for mixing said atomized/vaporized fuel with said air includes scroll means which also converts the velocity of the mixture caused by said blower to a pressure head; tubing means contained in said combustion chamber for carrying the fluid to be vaporized; and means for igniting said combustible mixture.
Claim 5
Dependent Claim
130 words
A vapor generator comprising: a housing having an air inlet and an exhaust; a porous member dividing said housing into a central plenum and a combustion chamber; a blower positioned to move air through said inlet; a fuel pump; a fuel atomizer/vaporizer; means for conveying fuel from said fuel pump to said antomizer/vaporizer; means for rotating said fuel pump and said blower at the same speeds; means for mixing said atomized/vaporized fuel with said air to form a combustible mixture; said means for mixing said atomized/vaporized fuel with said air includes scroll means which also converts the velocity of the mixture caused by said blower to a pressure head; tubing means contained in said combustion chamber for carrying the fluid to be vaporized; and means for igniting said combustible mixture.
Claim 6
Dependent Claim
15 words
A vapor generator according to claim 3 wherein: said scroll means is in said plenum.
Claim 7
Dependent Claim
15 words
A vapor generator according to claim 4 wherein said blower is in said scroll means.
