  • Patent number: 5685490
    Abstract: A fuel injector with a hydraulically actuated needle check includes a fuel pressurization chamber positioned between a low pressure fuel supply passage and a nozzle supply bore. A portion of the low pressure fuel supply passage is in direct fluid communication with the fuel pressurization chamber via a bleed hole. A bleed pin extends into a fluid supply chamber adjacent the bleed hole. The bleed pin is movable between a first position in which the bleed hole is open and a second position in which a portion of the bleed pin closes the bleed hole when the hydraulically actuated needle check moves between its closed position and its open position, respectively. A supply valve is positioned in the low pressure fuel supply passage between the low pressure fuel supply chamber and the fuel pressurization chamber in order to prevent the back flow of fuel from the pressurization chamber into the supply passageways.
