460,034. Vaporizers. GRUNBERGER, M., and NORDER, J. O. I. July 19, 1935, No. 20626. Convention date, July 20, 1934. [Class 7 (iii)] A liquid fuel supply tube extends horizontally through a vaporizing chamber. the bottom of which adjoins an exhaust gas conduit and is faced by spaced fuel admitting apertures in the tube, and the vaporizing chamber is so constructed and arranged that evaporation of the fuel takes place in the complete or almost complete absence of air, the vaporizing chamber leading to one end of a mixing chamber the other end of which is connected intermediately with a place of consumption such as the combustion space of an internal-combustion engine. Heavy fuel, which may be supplied by a pump past an adjustable valve, is sprayed through apertures 17 in a pipe 16 on to the base of an evaporating chamber 14 heated by exhaust gases passing through a surrounding casing 5. The chamber 14 forms the lower part of a tube 6 and is separated from the upper part by a partition 11, an aperture 12 being left adjacent one end of the chamber for the vaporized fuel to enter the upper part where it is mixed with air drawn through a self-closing valve 19. A limited quantity of air, insufficient for combustion, may be drawn into the vaporizing chamber 14 through a valve 25. At starting, an electric heater may vaporize the fuel, or a separate light fuel carburetter be used. The valve 19 may be replaced by a valve controlled simultaneously with a valve in the fuel supply conduit.
