Abstract
A carburettor for an internal combustion engine includes a chamber into which fuel is introduced from a metering valve to produce a fuel/air mixture in the chamber. A main valve controls the rate of flow of fuel/air mixture from the chamber and a further valve upstream of the main valve is provided the opening of which controls the opening of the metering valve. The further valve opens so as to keep the pressure between the main and further valve constant with changes in flow rate through the chamber. Means are provided to provide an indication of the pressure of fuel/air mixture downstream of the main valve such that the metering valve can be further opened as a function of changes in said pressure downstream of the main valve.
