Abstract
A plunger-type injection pump for use in automotive installations is provided not only with plunger rotating means to vary the quantity of fuel injected but also with a novel tappet assembly that includes hydraulically actuated facing nested parts that can be axially separated as well as angularly rotated relative one to the other to vary the height of the plunger from an initial setting in a continuously variable manner to thereby continuously vary the injection timing.
