ABSTRACT:
A fuel injection pump is proposed in which the fuel metering takes place during the intake stroke of the pump pistons via a fuel supply line in which a switching valve is mounted, which is opened upon the onset of the intake stroke of the pump pistons, closes in the course of this intake stroke and with this closing point also determines the injection onset upon the ensuing supply stroke of the pump pistons. The quantity of fuel to be injected is then limited by means of a pump-guided control edge, which is disposed on an annular slide provided on a free end of the distributor of the fuel injection pump; when a first control opening on the distributor which communicates with the pump work chamber coincides with a second control opening on the annular slide, the pump work chamber is relieved. The diversion or gradual shutoff point is controlled in the course of the compression stroke movement of the pump pistons by means of the relative rotation of the working point of the second control opening. By simultaneously affecting the switching valve and an adjusting device of the annular slide, the injection can take place at any arbitrary portion of the cam lobe curve of the cam drive of the pump pistons, as long as the requirements for the correct injection instants are met.
