ABSTRACT:
A fuel injection pump of the distribution type includes a load timer, and the load timer has a relief hole formed axially in a governor shaft, a first communication passage extending through a peripheral wall of the governor shaft surrounding the relief hole, and a second communication passage extending through a peripheral wall of a governor sleeve. One of the first and second communication passages has first and second control holes spaced axially from each other. The stroke of movement of the governor sleeve has a first movement region where the area of communication between the first control hole and the other communication passage decreases as the governor sleeve is retracted and a second movement region where the area of communication between the second control hole and the other communication passage increases as the governor sleeve is retracted.
