Abstract

Improvements in devices for the injection of fuel in internal combustión engines, with a fuel pump that provides a high and constant pressure of the fuel in a tank, with fuel connections from the tank to the points of fixation in the needles of the valves of injection and with a regulation device driven by an emitter driven synchronously with the machine and comprising a hydraulic control circuit, with which a regulating piston of each injection valve for the operation of the needle can be moved in rhythm. Of the valve, which is attacked by the pressure of the fuel existing in the dressing chamber, in the direction of opening, characterized in that the regulation device comprises at least one electromagnetic valve connected to an electric emitter and through which the chamber the cylinder of the regulating piston can be connected alternatively with a pressure line containing a constant pressure hydraulic fluid or with a discharge line.
