ABSTRACT:
A fuel injector for an internal combustion engine. The injector body contains a variable volume control chamber to and from which control fluid is supplied and drained to operate an intensifier piston which repetitively injects fuel from an injection chamber within the body. An electric-operated supply valve selectively controls flow of control fluid through a supply passage to the control chamber, and an electric-operated drain valve selectively controls flow of control fluid through a drain passage from the control chamber. Each valve is selectively operable independent of the other, and flow through the supply passage is independent of flow through the drain passage, and vice versa.
