Abstract
A fuel injection pump equipped with a rotary deflector having an increased lifetime and reduced maintenance cost required to replace the deflector when it is wasted due to cavitation erosion. The deflector comprises a stationary holder and a tip member which is supported rotatably by the stationary holder so that the tip member is rotated by fuel flow that outbursts from the plunger room through the inlet/spill port and impinges against the tip member when fuel injection ends. This evades concentrated impingement at a specific portion of the tip member and prevents the occurrence of cavitation erosion.
