Abstract
In a fuel injection pump including a plunger barrel provided with a fuel pressure chamber, a plunger which reciprocates within this plunger barrel to take in fuel from a fuel reservoir chamber and deliver this fuel from the fuel pressure chamber under pressure, and a timing sleeve which is positioned between the plunger and the plunger barrel such that it slidably mates with the outside of this plunger, and on which a spill port is formed; a fuel injection pump is characterized by an impingement-cushioning cavity being formed on the surface of the inside wall of the plunger barrel in a position opposite the spill port of the timing sleeve along with the peripheral surface of the timing sleeve being formed in a certain shape corresponding to this impingement-cushioning cavity.
