射時期制御装置。It has a piston that is actuated by pressure that constantly increases as the engine speed increases, and a spring device that biases the piston in a direction against the pressure, and controls the fuel injection timing according to the movement of the piston. In the injection timing control device for a fuel injection pump for an internal combustion engine to be controlled, the spring device regulates a first spring and displacement of the first spring, and controls the first spring only when the pressure acting on the piston is below a predetermined value. a stop member for actuating the first spring;
For an internal combustion engine, the second spring has a smaller spring constant than the spring, is set in advance to be displaced by a predetermined amount, and is activated when the pressure acting on the piston is equal to or higher than the predetermined value. Fuel injection pump injection timing control device.
