Abstract
A fuel injection pump comprises a rotor located in a housing, a free piston movably mounted in an axial bore of the rotor, two pump chambers which is formed by dividing said bore by the free piston, and two solenoid valves for supplying fuel to the two pump chambers, one of the chambers receiving therein the fuel to be injected and the other for effecting control of the injection timing. This injection pump is characterized in that two preparatory chambers are provided downstream of the solenoid valves to keep fuel measured by the solenoid valves during the compression operation of said pump chambers and transfer the fuel to said pump chamber after completion of the compression whereby precise measurement of the fuel can be effected.
