Abstract
This fuel injector assembly (1) is used to inject fuel into a combustion chamber (52) of an engine. It comprises a needle control unit (14) adapted to actuate a needle (15) to deliver fuel to the chamber (52), an amplifier unit (13) adapted to increase the pressure of a quantity of fuel coming from an accumulator (3) of fuel under pressure and a cam (4) driven feeder unit (12) adapted to feed the accumulator (3) with fuel under pressure. No external pump is needed to feed the accumulator (3).
