Abstract
A connector assembly and the actuating system including the connector assembly, the 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 includes a check valve operably disposed in a connecting member for controlling the flow of actuating fluid between the actuating fluid rail and the fuel injector. The connecting member has a fluid passageway defined therein, the fluid passageway being in fluid communication with the actuating fluid rail and the fuel injector actuating fluid inlet. A method of minimizing negative pressure effects caused by operation of a fuel injector on the actuating fluid in an actuating fluid rail and a method of providing a high pressure actuating fluid flow from a high pressure pump to a plurality of fuel injectors of a diesel engine are further included.
