する噴射量制限機構付き燃料噴射装置。 In a fuel injection pump, the fuel injection pump is equipped with a plunger that moves up and down and rotates according to the rotation of the engine to increase the pressure and pump the fuel, and a control sleeve that is fitted onto the plunger and controls the effective stroke by being moved by a tension lever. The pump has a chamber divided into upper and lower parts by a diaphragm at the upper part, a tiltable lever for moving the tension lever, and a downwardly widening tapered part for moving a pressing pin in contact with the lever, and the upper part is connected to the diaphragm. It has a connected low-cut pin and a spring that is located in an upper chamber partitioned by a diaphragm and always biases the low-cut pin downward via the diaphragm, and the upper chamber is connected to the upper chamber only when it is necessary to limit the injection amount. A fuel injection device with an injection amount limiting mechanism, characterized in that it is connected to a vacuum pump for introducing negative pressure.
