Abstract
A fuel supply device for internal combustion engines has an injector formed with an injection orifice whose cross-sectional area is adjusted responsive to the position of an auxiliary throttle element located in the intake pipe of the engine and opening automatically and progressively in dependence upon the rate of engine intake air flow. The area is also adjusted as an increasing function of the difference between the pressures upstream and downstream of the auxiliary throttle element.
