Abstract
A piezoelectric actuated fuel injector is provided for use in conjunction with an internal combustion engine. The fuel injector includes a piezoelectric actuator for actuating an injector valve, and a hydraulic assembly for interfacing between the piezoelectric actuator and the injector valve, where the injector valve axially separates from a discharge outlet in response to longitudinal expansion of the piezoelectric actuator, thereby allowing fuel flow from the fuel injector.
