ポンプ。[Scope of Claim for Utility Model Registration] 1. A plunger that rotates and reciprocates the fuel oil in a pump chamber filled with fuel oil at a pressure corresponding to the engine speed and pressurizes and distributes it to each cylinder; A governor mechanism that adjusts the injection amount by driving a control sleeve that engages with the plunger, and a governor mechanism that rotates according to the rotation speed of the engine and controls the injection amount when the rotation speed of the engine exceeds a predetermined rotation speed. In a distribution type fuel injection pump comprising a centrifugal force governor that controls the engine speed by driving in a decreasing direction, the engine speed exceeds the predetermined speed in response to fuel pressure in the pump chamber. A governor correction device is provided that is activated by the fuel pressure when the fuel pressure is applied to drive the governor mechanism in a direction to decrease the injection amount, and the governor mechanism is driven in cooperation with the centrifugal speed governor. A distribution type fuel injection pump featuring: 2. The governor correction device includes a cylinder that is fitted into a hole drilled in a pump housing and has one end opening into the pump chamber, and a cylinder that is slidably fitted and housed in the cylinder and has one end that opens into the pump chamber. a first pin having a pressure-receiving end surface that receives pressure and having a substantially tapered cam surface formed at a predetermined position on the circumferential surface thereof, the diameter of which decreases in the direction of the opposite pressure-receiving end along the axial direction; and a non-pressure-receiving end surface of the first pin. and a spring that is interposed between the pump housing and biases the first pin toward the pump chamber, and a spring that is bored in the pump housing in a radial direction of the first pin and facing the cam surface. a second pin that is slidably inserted into the hole and has one end in contact with the cam surface; a second pin that is rotatably supported in a predetermined position in the pump chamber, one end of which is connected to the other end of the second pin; The distribution type fuel injection pump according to claim 1, further comprising a lever that comes into contact with a tension lever of the governor mechanism.
