Abstract
A fuel injection apparatus in which the duration of fuel supply of at least two pump pistons of a fuel injection pump is determined by the closing duration of an electrically actuated overflow valve. The overflow conduits of at least two adjacent pump work chambers are interconnected, and the return flow of fuel from these overflow conduits to a chamber of lower pressure is controllable by the control element of the overflow valve which is common to these overflow conduits. The overflow conduits are each provided with one barrier valve, by means of which the at least one pump work chamber not under injection pressure at a given time can be blocked off from the pump work chamber which is placed under injection pressure at that time.
