ABSTRACT:
A fuel injector having therein a pressure chamber connected to a nozzle bore. Fuel in the pressure chamber is pressurized by a plunger driven by an engine and is injected from the nozzle bore when the pressure in the pressure chamber exceeds a predetermined pressure. The volume of the pressure chamber is controlled by a piston device actuated by low pressure. The movement of the piston device prevents the injection of fuel. The injection of fuel is stopped by causing the piston device to move relatively freely.
