Heated fuel vapourizer and slidable throttle valve.

摘要

Apparatus for supplying a gaseous fuel mixture to a combustion chamber. A fuel vapourizer (10) vapourizes liquid fuel which is then mixed with air. The vapourizer and mixing chamber (12) are heated to maintain the temperature of the vapourized fuel/air mixture. The vapourizer and mixing chamber are also interconnected so that vapourized fuel is discharged directly from the vapourizer into the mixing chamber.

A simplified valve for controlling the quantity of vapourized fuel discharged into the mixing chamber is provided.
