Abstract
A temperature compensated fuel control valve or regulator has a temperature sensor which senses the temperature of fuel entering the regulator. The temperature sensor controls the area of an orifice through which the fuel must pass in order to enter the burner. When the fuel is at low temperature, its viscosity will be higher and more of the orifice area will be exposed to the fuel. When the fuel is at high temperature, it will flow more easily and less of the orifice will be exposed to the fuel thereby allowing less fuel to pass to the burner.

An improved fuel vaporizer apparatus comprising a burner uptube for carrying liquid fuel and vaporizing said liquid fuel, said burner uptube extending substantially vertically and having a longitudinal distance defined by a first open upward end and a second end opposed from said first open upward end, said burner uptube being adapted to be centrally located within a burner, said liquid fuel being vaporized between said first open upward end of said burner uptube and said second end opposed from said first open upward end, said burner uptube having an outer circumference, a cap centrally located over said first open upward end of said burner uptube, a casing having a longitudinal axis and an inside circumference, said casing having a first end adjacent said cap and a second end opposed from said first end, said casing extending downwardly from said cap around said burner uptube for a substantial portion of said longitudinal distance of said burner uptube and an annulus defined by said outside circumference of said burner uptube and said inside circumference of said casing, said annulus extending over a substantial portion of said longitudinal distance of said burner uptube, said annulus communicating with said first upward open end of said burner uptube, and being operable to carry fuel vapour received from said burner uptube downwardly and to disperse said fuel vapour around and in contact with said outside circumference of said burner uptube, said burner uptube being uninsulated in the area of said annulus, said annulus including a plurality of tubes extending downwardly from said cap and having axes parallel to the axis of said burner uptube.
