Abstract

A distributor type fuel injection pump for distributing and supplying pressurized fuel into combustion chambers of an internal combustion engine, is described comprising: a rotor driven to be rotated; a pair of plungers slidably reciprocated in a radial direction and coaxially with each other in the rotor, the plungers defining a pump chamber therebetween; a shuttle cylinder portion in which a cylinder bore is defined; a shuttle piston movably disposed in the cylinder bore and dividing the interior of the cylinder bore into first and second pressure chambers; connecting means for continuously connecting the pump chamber and the second pressure chamber; supply means for supplying the fuel into the pump chamber and the second pressure chamber through the connecting means and also supplying the fuel into the first pressure chamber.
