<p>Herein disclosed is a distribution type fuel injection pump for distributing and pumping a fuel into a plurality of cylinders of an internal combustion engine. The fuel injection pump is constructed of a hydraulic head (14) formed with first and second fuel feed ports (28, 30), a rotor (16) fitted in the hydraulic head (14), and plungers (60) fitted in the end portion of the rotor (16) for effecting the pumping action in accordance with the rotations of the rotor (16). Separately of this rotor (16), moreover, there ist formed in the hydraulic head (14), for example, a pressure space in which a shuttle (70) is slidably fitted to partition the pressure chamber into first and second pressure chambers (72, 74). With the construction thus far described, the fuel, which has been introruded from the first fuel feed port (28) and compressed by the plungers (60), is guided into the first pressure chamber (72) of said pressure space in accordance with the rotations of the rotor (16), and the fuel, which is introduced into the second pressure chamber (74), is consecutively distributed and pumped into the respective engine chambers by the movements of said shuttle (70). </p> |
