ABSTRACT:
A hydraulically-actuated fuel injector includes an injector body that defines an upper actuation fluid cavity, a lower actuation fluid cavity, an actuation fluid inlet, a spill passage, a piston bore and a nozzle outlet. A control valve member is positioned in the injector body and moveable between a first position and a second position. An intensifier piston is positioned in the piston bore and moveable between a retracted position and an advanced position. The piston has a primary hydraulic surface exposed to fluid in the upper actuation fluid cavity, and an opposing hydraulic surface exposed to fluid in the lower actuation fluid cavity. The upper actuation fluid cavity is open to the actuation fluid inlet, and the lower actuation fluid cavity is open to the spill passage when the control valve member is in its first position. The spill passage is blocked when the control valve member is in its second position.
