Vaporizer for liquid fuel for producing a fuel-air mixture

Abstract

A vaporizer for liquid fuel for producing a fuel-air mixture including a orization member for the fuel and which is arranged within a flow chamber for combustion air. The surface of the vaporization member which is streamed against by the combustion air is moistened with fuel. The vaporizer incorporates a vaporizing member arranged within a flow chamber for combustion air, wherein the vaporizing member includes a rotatable or circulating filling or charge of balls whose temperature can be adjusted through heat conduction received from the walls of the flow chamber. Thereby, through the revolving or circulation of the ball filling, and the heat transfer to the balls which are currently at the edge of the ball filling in heat-conductive communication with the temperature-regulated walls of the flow chamber, there takes place a rapid and uniform heating of the ball filling. The large vaporization surface which is made available through the ball filling, additionally allows for the formation of relatively thin fuel films, which can be heated while concurrently avoiding excessive temperatures. The revolving or circulating of the balls additionally provides for a constant movement and displacement of the vaporizing member, as a result of which there can be avoided striated or streaky flows which lead to a non-uniform or irregular formation of the fuel-air mixture.
