Claims

[Claims for Utility Model Registration] 1. Based on the fact that the reciprocating and rotating plunger performs suction and pressure feeding and distribution of fuel, the injection timing is controlled by the fuel pressure in the chamber that changes in relation to engine rotation. In the distribution type fuel injection pump, a stop lever is provided that engages with the start lever to move the fuel in the direction of decreasing fuel, and an actuator that is moved by the fuel pressure in the chamber is attached to the stop lever, so that the pressure in the chamber is maintained at a predetermined level. This distribution type fuel injection pump is characterized in that after the pressure has risen to the desired level, the actuator moves to move the stop lever to eliminate the starting stroke. 2. The distribution type fuel injection pump according to claim 1, wherein the actuator has two pressure receiving parts. 3. A distribution type fuel injection pump according to claim 1 of the registered utility model, characterized in that fuel pressure is supplied to the chamber of the actuator via a solenoid valve. 4 Claim No. 3 of the utility model registration, characterized in that the solenoid valve is controlled by the rotation speed and water temperature. Distribution type fuel injection pump as described in Section 1.
