Injector actuating fluid check and methods

A connector assembly for fluidly coupling an actuating fluid rail to a certain fuel injector, the actuating fluid rail conveying a quantity of high pressure actuating fluid, the connector assembly comprising:

• a check valve operably disposed in a connecting member for checking the flow of actuating fluid to the actuating fluid rail from the fuel injector, the connecting member having a fluid passageway defined therein, the fluid passageway being in fluid communication with the actuating fluid rail and the fuel injector.

An actuating fluid system for use with an engine having at least one bank of cylinders, the actuating fluid system having a high pressure pump providing high pressure actuation fluid to an actuating fluid rail servicing a plurality of fuel injectors of each bank of the at least one bank of cylinders, there being no check between the high pressure pump and the actuating fluid rail servicing each bank of the at least one bank of cylinders, a connector assembly for fluidly coupling an actuating fluid rail to a fuel injector, the actuating fluid rail conveying a quantity of actuating fluid, the fuel injector having an actuating fluid inlet, the connector assembly comprising:

• a check valve operably disposed in a connecting member for checking the flow of actuating fluid to the actuating fluid rail from a certain fuel injector, the connecting member having a fluid passageway defined therein, the fluid passageway being in fluid communication with the actuating fluid rail and the certain fuel injector actuating fluid inlet.
