<p>Provided is a fuel injection pump capable of suppressing the occurrence of cavitation. The fuel injection pump comprises: a pump case; a plunger barrel (30) formed in a tube shape and housed inside the pump case; an oil supply/discharge hole (35) penetrating a peripheral wall section (31) of the plunger barrel (30) and discharging at least the fuel inside the plunger barrel (30) to outside the plunger barrel (30); a plunger (45) slidably arranged inside the plunger barrel (30), pressurizing the fuel inside the plunger barrel (30), and opening and closing an opening (36) that opens to the inner peripheral surface of the plunger barrel (30) in the oil supply/discharge hole (35); and a deflector (40) rectifying fuel flowing inside the oil supply/discharge hole (35), and arranged inside the oil supply/discharge hole (35), positioned eccentrically towards the opening commencement side when the opening section (36) is opened using the plunger (45) during discharge of fuel inside the plunger barrel (30) from the oil supply/discharge hole (35).</p> |
