ABSTRACT:
A hydraulically-actuated fuel injector includes an injector body having a nozzle chamber, a nozzle outlet, an actuation fluid inlet, an actuation fluid drain, an actuation fluid cavity and a pressure relief passage extending between the actuation fluid cavity and the actuation fluid drain. A hydraulic means, including an actuation fluid control valve mounted within the injector body, is used for pressurizing fuel in the nozzle chamber. A needle valve member is mounted to reciprocate in the nozzle chamber between an open position in which the nozzle outlet is open and a closed position in which the nozzle outlet is closed. A relief valve is mounted within the injector body and has a first position in which the pressure relief passage is closed and a second position in which the pressure relief passage is open.
