Abstract: A fuel injection system for externally ignited, gas internal combustion engines. The system is of the type which involves continuous injection into an induction tube in which a measuring member and a randomly activated throttle are arranged in series. The measuring member is embodied on a plate disposed, under quiescent conditions, at a right angle to the flow direction on one end of a pivoted lever. The plate projects proportionally to the amount of air flowing through the induction tube into a corresponding funnel-shaped section of the induction tube. The lever is operatively arranged to operate a mobile member of a valve which meters out fuel proportional to the quantity of air. The measuring member is displaced backwardly past its quiescent position, when a backfire occurs, in the induction tube, against the force of a spring having a linear characteristic and is caught by a resilient, elastic stop which converts a considerable amount of the kinetic energy into heat and returns the measuring member toward its quiescent position.
