Fuel system having fixed geometry flow regulating valve for limiting injector cross talk

A fuel injector comprising:

• an injector body having a high pressure nozzle supply passage, a check control chamber, and a low pressure outlet formed therein;
• a direct operated nozzle check;
• an injection control valve assembly;
• and
• a pressure regulating valve having a static geometry and positioned fluidly between the check control chamber and the low pressure outlet.

A method of operating a fuel system comprising:

• moving an injection control valve in a first fuel injector in the fuel system from a closed position to an open position;
• fluidly connecting a check control chamber in the first fuel injector to a low pressure outlet of the first fuel injector in response to the moving of the injection control valve;
• producing a pulse of fluid pressure in response to the fluidly connecting of the check control chamber to the low pressure outlet;
• feeding the pulse of fluid pressure to a pressure regulating valve having a static geometry and positioned fluidly between the check control chamber in the first fuel injector and a second fuel injector in the fuel system;
• and
• limiting cross-talk between the first fuel injector and the second fuel injector based on an attenuation of the pulse of fluid pressure by the pressure regulating valve.
