Abstract
A carburetor for an internal combustion engine comprises a control for maintaining the pressure of the fuel supply through the carburetor constant. The control includes a sensing device, which is preferably a level sensing device, and a fuel feed valve which is automatically operated by the sensing device. The sensing device produces signals which operate the valve to control the rate of fuel supply to the carburetor and, in order to provide an indication of the instantaneous rate of fuel consumption of an engine to which the carburetor is fitted, these signals are also fed to a fuel flow indicator. The fuel flow indicator produces a reading of the fuel flow rate either in dependence upon the frequency of opening of the valve when the opening period is constant, or in dependence upon the period for which the valve is open when the frequency of opening of the valve is constant.
