ンプの噴射時期調整装置。 The hydraulic pressure supplied to the pressure oil chamber formed at one end of the timer piston is controlled by the sliding displacement of the servo valve provided on the timer piston, depending on the balance between the oil supply pressure from the pump chamber and the spring force of the timer spring. In the injection timing adjustment device for a distribution fuel injection pump, the injection timing adjustment device for a distribution fuel injection pump is equipped with a servo valve mechanism that can adjust the injection timing by displacing a timer piston and rotating a roller holder. and a biasing holding means for forcibly holding the timer piston in a direction in which the timer piston is advanced; and the servo valve operates in response to temperature and is actuated by the biasing holding means when the sensed temperature is equal to or higher than a predetermined set value. An injection timing adjustment device for a distribution type fuel injection pump, comprising a release means for releasing the energized state.
