Abstract

176,302. White, A. E., (Rector Carbureter Co., Inc.). Aug. 24, 1920. Vaporizers, external.-Fuel to be vaporized enters an annular chamber 31, and passes by two pipes 81 to a flat chamber 76; a trapped outlet from the chamber connects with the pipe 80, which passes through the centre of the heating- chamber and forms a final heating-chamber. Projections 33 on the inner wall of the chamber 31 conduct heat to the walls. Fuel for the burner is led to the annular vaporizing chamber 47, the vapour passing through the T-shaped pipe 52 to two inclined nozzles. At starting, air for the burners is admitted through a ring of ports 37 opened by the hand-actuated valve 86. Normally a fan supplies the air for the burner through the pipe 41 and four outlets 40; baffles 54 on the chamber 47 prevent a free flow of air from these outlets. The burner is kept alight by a sparking- plug 73, which may be in series with the plug on the engine cylinder. The products of combustion, after impinging on the chamber 47, pass over the pipe 80 and through the chamber formed inside the annular chamber 31; part of these products escape through holes 88 in the top of cover 89 and part pass outside the chamber 31, escaping at the bottom 87. The vaporized fuel for the engine passes to a carburettor 15. A single fuel-pump supplies the fuel to be vaporized and the burner.
