Abstract

A fuel injection apparatus particularly suitable for high-powered engines, in which the pressure chamber of the fuel injection valve or valves is relieved of pressure during the pauses between injections by means of a correspondingly controlled obturation mechanism so that, when the valves are not tight, the undesirable injection of fuel during the pauses between injections is substantially prevented.
