Claims

[Scope of utility model registration request]

A pump mechanism that pressurizes the fuel, and a rotary body formed with a high-pressure fuel passage communicating with the pump mechanism and rotating in synchronization with the crankshaft of the internal combustion engine, distributes the fuel discharged by the pump mechanism to each cylinder of the internal combustion engine. A distribution mechanism and a control sleeve formed with a fuel discharge passage communicating with the upstream side of the pump mechanism engage with each other so as to communicate the fuel discharge passage with the high-pressure fuel passage by relative displacement with the rotating body, A distribution fuel injection pump comprising: an injection amount control mechanism that controls the amount of fuel supplied to a cylinder; and an actuator that drives the control sleeve to cause a relative displacement with the rotating body; A distribution type fuel injection pump, characterized in that the pump is provided at a position substantially perpendicular to the rotation axis of the rotary body.
