| description | A fuel injector with inlet and discharge ends includes a fuel tube through which fuel is admitted to a fuel passage extending to the discharge end. A valve element reciprocates against and away from a valve seat to prevent or allow fuel discharge. A calibration tube includes first and second ends and defines a portion of the fuel passage through which fuel must pass to the discharge end, the second end defining a spring seat engaging a spring and biasing the spring against the valve element. A fuel filter filters all fuel passing to the discharge end, and provides restriction of a first magnitude. The calibration tube includes a pressure pulsation damping orifice fluidly between the fuel filter and the discharge end through which fuel must pass to the discharge end, the pressure pulsation damping orifice provides restriction of a second magnitude which is greater than the first magnitude. |
