料噴射ポンプの噴射量補正装置。 The rotational motion transmitted from the internal combustion engine is converted by a cam roller and a face cam that contacts the cam roller so that the plunger is reciprocated several times during one revolution of the engine, and the reciprocating motion of the plunger discharges the fuel in the pressure pump chamber. The fuel is pressurized and supplied to each cylinder of the internal combustion engine, and the amount of fuel to be injected is regulated by moving a spill ring slidably fitted to the plunger to open a spill port opened in the plunger, and the spill ring In a distribution type fuel injection pump, the position of which is adjusted by a tension lever that is affected by accelerator operation and a centrifugal speed governor to control the fuel injection amount, the adjustment rod operates in response to fuel pressure in the fuel chamber and has a cam surface. , a movable wall that receives boost pressure and atmospheric pressure and is displaced by the difference in these pressures, a spring inserted between the adjustment rod and the movable wall, and a movable wall that operates in response to boost pressure. A spring that presses the movable wall against the movable wall, a stopper that restricts the amount of movement of the movable wall, a transmission rod that comes into contact with the cam surface of the adjustment rod and is actuated by the displacement of the cam surface, and An injection amount correcting device for a distribution type fuel injection pump, comprising: a rotary lever that transmits movement to the tension lever.
