摘要： A directly actuated injection valve comprises a hollow valve housing, a valve needle disposed within the hollow interior, a needle spring, and a magnetostrictive actuator assembly disposed in an annular space around a portion of the valve needle. A magnetic field actuates the magnetostrictive material to change its length to cause a corresponding movement of the valve needle that actuates the valve. The valve needle is comprises of a plurality of portions. The portion of the needle that extends through the magnetostrictive actuator assembly is formed from a non-ferromagnetic material and the portion of the needle comprising the needle tip, which contacts the valve seat, is formed from a different material that has higher through-hardness than that the non-ferromagnetic material. The portion of the needle formed from a non-ferromagnetic material prevents interference with the flux field that is directed through the magnetostrictive member. The use of a different material for the needle tip reduces the effects of wear and improves durability.

摘要： A directly actuated injection valve comprises a hollow valve housing, a valve needle disposed within the hollow interior, a needle spring and a tubular magnetostrictive actuator assembly disposed in an annular space around a portion of the valve needle. A magnetic field activates the magnetostrictive material to change its length to cause a corresponding movement of the valve needle that actuates the valve. The valve needle is formed from a ferromagnetic material and extends through the tubular magnetostrictive actuator assembly without interfering with the flux field that is directed through the magnetostrictive member. A passive hydraulic link assembly is preferably employed to compensate for component wear, temperature effects and manufacturing variations within design tolerances.

摘要： A fuel injector, in particular a fuel injector for fuel-injection systems of internal combustion engines has a piezoelectric or magnetostrictive actuator, a valve closure member which can be actuated by the actuator via a valve needle and which cooperates with a valve seat face to form a sealing seat, and a translating device arranged between the actuator and the valve needle for translating an actuator lift of the actuator into a larger valve needle lift of the valve needle. In this context, the translating device includes at least one lever plate having at least one rigid lever segment running radially.

摘要： An electrically operated valve in which the valve operating means is controlled in its opening movement by a piezoelectric element. The expansion or contraction of the piezoelectric element provides a lift force to the valve operating means while, preferably, a hydraulic or mechanical amplification stage is included to provide an exceedingly rapid mode of operation. The valve is particularly advantageous to control the multiple and discrete injections of fuel into an internal combustion engine.

摘要： A fuel injector assembly in one embodiment includes a nozzle, at least one needle, and at least one actuator. The nozzle includes at least one cavity in fluid communication with nozzle openings. The at least one needle is movably disposed within the at least one cavity, and prevents flow through the nozzle openings in a closed position. The at least one actuator is configured to move the at least one needle within the cavity. The at least one actuator is configured to move the at least one needle to at least a first fuel delivery configuration and a second fuel delivery configuration. A first amount of fuel is delivered through the nozzle openings with the at least one needle in the first fuel delivery configuration, and a second amount of fuel is delivered through the nozzle openings with the at least one needle in the second fuel delivery configuration.
