Document Type and Number:
Japanese Patent JPH0658100
Kind Code:
B2
Abstract:
A distributor type fuel injection pump of the invention includes a rotor (3), a pair of plungers (42) reciprocated in the rotor (3), the pair of plungers (42) defining a pump chamber (43a) therebetween; a shuttle cylinder (6l); a shuttle piston (63), movably located in the shuttle cylinder (6l), for dividing the interior of the shuttle cylinder (6l) into first and second pressure chambers (62a, 62b), the second pressure chamber being always connected to the pump chamber, thereby pressurizing the fuel in the second pressure chamber (62b) by pressurization of fuel in the pump chamber (43a) by the plungers and moving the shuttle piston (63) to pressurize the fuel in the first pressure chamber (62a); a distribution head (5) for distributing and supplying the pressurized fuel in the first pressure chamber (62a) to each combustion chamber of the engine; a control rod (65) for mechanically adjusting an initial position of the shuttle piston (63) when the fuel is supplied to the first and second pressure chambers (62a, 62b); and a spill hole (7l) for spilling the fuel in the second pressure chamber (62b) when the shuttle piston (63) is moved from the initial position toward a final position by the pressure of the pressurized fuel in the second pressure chamber and reaches the final position.
