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 a nozzle cavity formed in a nozzle housing containing a nozzle valve element. The hydraulic link assembly is positioned close to the injector orifices to minimize needle valve element length and mass, thereby reducing seat impact forces and enhance response time. A refill valve operates to move into an open position to refill a hydraulic link chamber. An actuator power source operates to vary voltage to cause multiple injection pulses and to selectively maintain the voltage above a predetermined lower level between injection pulses to maintain the refill valve in a closed position to prevent refilling of the hydraulic link chamber.

摘要： A fuel pump is disclosed wherein a substantially cylindrical plunger bore is provided with an annular drain groove fluidically coupled to a drain duct. A pump plunger is driven by a drive system located in a separate mechanical compartment that holds a reservoir of lubricating oil. An annular seal is provided adjacent the drain groove substantially at the end of the bore and retained in position by a seal support. Exemplary embodiments provide the drain groove and seal as being positioned immediately adjacent one another so that the seal forms a lower wall of the drain groove.

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.
