Abstract: A fuel injector is disclosed herein. The fuel injector includes an injection line, a control valve, a check rod, a control cavity, a high pressure inlet, and a drain line. The injection line fluidly connects a fuel inlet to an injection cavity. The control cavity is adjacent an upper end of the check rod distal to the injection cavity. The high pressure inlet fluidly connects the injection line to the control cavity. The control valve blocks the flow of fuel from the control cavity to the drain line when the control valve is in a closed position and does not block the flow of fuel from the control cavity to the drain line when the control valve is in an open position.
