噴射ポンプのA plunger that rotates and reciprocates in synchronization with engine rotation;
The plunger has a control sleeve that is slidably fitted in an oil-tight manner, and the position of the control sleeve is adjusted based on the displacement force of the flyweight and the governor spring. Controlling the outflow area of the through hole, which allows fuel in the pump 7° chamber to flow out to the suction side of the oil pump through the passage of the sleeve holder from the recessed hole provided in the sleeve that presses the start lever, according to the load. In the injection timing control device for a distribution type fuel injection pump in which the reciprocating timing of the plunger is controlled by a timer piston, one timer piston is connected from the pump chamber to the timer operation chamber in parallel with an orifice between the timer operation chamber and the pump chamber. A distribution type fuel injection pump characterized by having a check valve that shuts off the flow of oil.
