１項記載の分配型党料噴射、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 distributes pressure to each cylinder, and a control and a lever that respond to the pressure. a governor mechanism that adjusts the injection amount by driving a control leaf that engages with the plunger; and a governor mechanism that rotates in accordance with the rotational speed of the engine and when the rotational speed of the engine exceeds a predetermined rotational speed. and a centrifugal speed governor that controls the engine rotational speed by driving the engine in a direction to reduce the injection amount, and the distribution type fuel injection pump is installed in a supercharged internal combustion engine,
governor correction that operates in response to the boost pressure supplied to the engine section and operates with the boost pressure when the engine rotational speed force j exceeds the predetermined rotational speed to drive the governor mechanism in the direction of decreasing the injection amount; A distribution type fuel injection pump characterized in that a device is provided to drive the governor mechanism in cooperation with the centrifugal speed governor. 2. The above-mentioned BANA correction device is provided in the pump housing and includes a pressurizing chamber that introduces a part of the supercharging pressure to be supplied to the engine, and a partition wall of the pressurizing chamber, which is displaced according to the supercharging pressure. a diaphragm; a cylinder fitted into a hole drilled in the pump housing and having one end facing the pump chamber and being closed; a cylinder slidably fitted into the cylinder and having one end engaged with the diaphragm; A pin is provided with a substantially tapered cam surface whose diameter decreases in the direction opposite to the diaphragm end along the axial direction at a predetermined location on the circumferential surface, and the pin is interposed between the □ diaphragm and the pump housing to move the diaphragm toward the pressurizing chamber. and a lever rotatably supported at a predetermined location in the pump chamber, one end of which contacts the cam surface and the other end of which contacts the tension lever of the governor mechanism. Distributed type fuel injection and pump as set forth in claim 1.
