Fuel injector

A fuel injector (1) comprising a housing (2) with a nozzle (4), a needle (3) movably accommodated in a needle accommodating chamber (5) formed in the housing (2), for opening or closing the nozzle (4), a pressure control chamber (8) defined between the needle (3) and an inner wall of the needle accommodating chamber (5) and filled with a fuel, a displacement of the needle depending on the fuel pressure in the pressure control chamber (8), a pressure control valve (14) movably provided in the housing for controlling the fuel pressure in the pressure control chamber (8); and an actuator (15) for controlling a displacement of the pressure control valve (14). The needle (3) is displaced to a position in which it closes the nozzle (4) when the pressure control valve (14) is displaced to the zero-displaced position, is displaced to a position in which it partly opens the nozzle when the pressure control valve (14) is displaced to an intermediate position, and is displaced to a position in which it fully opens the nozzle when the pressure control valve (14) is displaced to a fully-displaced position.
