摘要： A piezoelectric-actuated fuel injector for injecting fuel into a combustion chamber of an internal combustion engine is provided which includes a piezoelectric actuator movable to expand in a first direction and movable to contract in a second direction opposite the first direction, and a hydraulic link assembly disposed within said injector cavity. The hydraulic link assembly includes a hydraulic link barrel having an inner bore, a hydraulic link outer plunger positioned to slidably move in the inner bore, and a hydraulic link operatively connected to a needle valve to move the needle valve in the second direction toward the open position in response to movement of the piezoelectric actuator in the first direction. A hydraulic link inner plunger is attached to the needle valve and extends into a center bore of the hydraulic link outer plunger. Leakage control features and hydraulic link refill valves are also provided.

摘要： A closed nozzle injector for injecting fuel at high pressure into the combustion chamber of an engine, is provided including a lower supply chamber positioned in the nozzle housing, an injector plunger including a lower guide sized to form a close sliding fit with a nozzle housing to guide the plunger during reciprocal movement, and a plurality of restriction orifices formed in the injector plunger and positioned about the injector plunger to restrict fuel flow from an upper supply chamber to the lower supply chamber. The lower guide is positioned axially between the lower supply chamber and the injection orifices.
