とを特徴とする分配型燃料噴射ポンプの噴射時期
調整装置。 It opens into a low pressure chamber where the timer spring is fitted.
The roller holder is rotated by a timer piston, which has an inlet that communicates with the low-pressure oil chamber of the feed pump and slides inside the cylinder 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 type fuel injection pump, the injection timing can be adjusted by adjusting the injection timing, by providing a stepped portion offset in the axial direction on the outer peripheral surface of the timer piston facing the introduction port, An injection timing adjustment device for a distribution type fuel injection pump, characterized in that the internal pressure in the low pressure chamber does not increase when the timer piston moves toward the advance side.
