Abstract
A fuel injector pump for an internal combustion engine including a camshaft-driven fuel delivery plunger, a solenoid valve for controlling transfer of liquid fuel from a fuel plunger cavity to a fuel injector nozzle, and a snubber valve located between the fuel injector nozzle and the plunger whereby unrestricted fuel flow is distributed to the injector nozzle and reverse flow from the nozzle to the plunger chamber is restricted so that cavitation in the fuel delivery passage extending to the nozzle will be avoided and undesirable pressure peaks at the fuel pump are avoided.
