ABSTRACT:
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.
