Abstract
A flow controller assembly for use with a hydraulically-actuated, electrically-controlled fuel injector, includes a flow controller fluidly disposable intermediate an injector control valve assembly and an injector intensifier assembly for controlling flow of actuating fluid to and from the intensifier assembly to effect rate shaping of an injectable quantity of fuel and to effect a reduction of noise generated by the stopping of return motion of an intensifier piston. A fuel injector and a method of controlling an intensifier piston are also included.

A flow controller assembly for use with a hydraulically-actuated, electrically-controlled fuel injector, comprising:
- a flow controller fluidly disposable intermediate an injector control valve assembly and an injector intensifier assembly for controlling flow of actuating fluid to and from the intensifier assembly to effect rate shaping of an injectable quantity of fuel and to effect a reduction of noise generated by stopping of an intensifier piston.
A governor plate apparatus for use with a hydraulically-actuated, electrically-controlled fuel injector, comprising:
- a flow controller fluidly disposable intermediate an injector control valve assembly and an injector intensifier assembly for controlling flow of actuating fluid to and from the intensifier assembly to effect rate shaping of an injectable quantity of fuel and to effect a reduction of noise generated by stopping of an intensifier piston.
A hydraulically-actuated, electrically-controlled fuel injector, comprising:
- an injector control valve assembly;
- an injector intensifier assembly being selectively in fluid communication with the injector control valve assembly;
- and
- a flow controller fluidly disposed intermediate the injector control valve assembly and the intensifier assembly for controlling flow of actuating fluid to and from the intensifier assembly to effect rate shaping of an injectable quantity of fuel and to effect a reduction of noise generated by stopping of an intensifier piston.
The fuel injector of claim 54, the checked passage being in fluid communication with a flow area defined in the lower margin of the flow controller, the flow area being in fluid communication with the actuation surface and exposing the nominal portion of the actuating surface to actuating fluid when the intensifier piston is seated against the flow controller return seat.
In a hydraulically-actuated, electrically-controlled fuel injector, a method of controlling an intensifier piston, comprising:
- controlling flow of actuating fluid to the intensifier piston to effect rate shaping of an injectable quantity of fuel by means of a flow controller;
- and
- controlling flow of actuating fluid from the intensifier piston by means of the flow controller to effect a reduction of noise generated by an intensifier piston as the intensifier piston seats on a return seat.
