Abstract (en)

[origin: US4705005A] A fuel injection pump for internal combustion engines, in which at least during normal engine operation the injection quantity is effected by controlling a fuel quantity control conduit which is provided in the pump piston in communication with the pump work chamber, via a control slide that is displaceable on the pump piston in cooperation with fuel quantity control openings, the axial position of the control slide determining the onset and end of supply. The earliest possible supply onset is further determined by a supply onset control opening disposed in the pump piston, which opening is sealed by entering into the cylinder liner after a pre-determined stroke extent has been traversed. Subsequent to this entry, an injection pressure can build up in the pump work chamber.
