摘要： In a distributor type fuel injection pump and a power transmission pump for transmitting power to the fuel injection pump, when a rotation system member of the injection pump is seized if anything should happen, only an injection pump is damaged to thereby greatly reduce damage to an engine. To this end, an annular groove is provided in a rotor to which power from the engine is transmitted, and the annular groove constitutes a frail portion of the rotor. The annular groove is positioned along the rotor so that all or most of the sliding portions of the rotor are located on a side of the groove opposite to a power supply side. When seizure occurs in the sliding portions of the rotor to prevent rotation, the rotor is twisted off at the annular groove by the power from the engine, so that rotation of a power supply side portion of the rotor is not prevented.

摘要： In an innercam system fuel injection pump, plungers 15 are provided in the direction of the radius of a rotating member 10 which rotates in synchronization with the engine. A cam ring 18, which regulates the movement of the plungers, is fixed in a housing 2. A first sleeve 25 for regulating the timing with which a cutoff port 22 opens and a second sleeve 26 for regulating the timing with which an intake port 21 opens are externally fitted on the rotating member 10 in such a manner that they can slide freely. The first sleeve 25 and the second sleeve 26 interlock with each other in a specific relationship and a timer mechanism 40, which is directly linked to the second sleeve 26, controls the quantity of rotation of the second sleeve 26. With this, stable injection timing control can be achieved.
