Abstract

Provided is a piezoelectric valve which is capable of stably supplying gas even when the gas jet time becomes longer, and is excellent in responsiveness when being open. A piezoelectric valve comprises a gas pressure chamber which receives compressed gas supplied from the outside, and a gas discharge path through which the compressed gas is discharged from the gas pressure chamber, the piezoelectric valve being provided with: a valve element which is disposed in the gas pressure chamber and opens and closes the gas discharge path; a piezoelectric element which generates, as displacement, driving force required for the operation of the valve element; a displacement magnification mechanism which magnifies the displacement of the piezoelectric element and causes the displacement to act on the valve element; and a driving means which has a signal generation unit for generating a signal composed of a pre-pulse and a main pulse, and drives the opening of the valve element by applying driving voltage to the piezoelectric element with the signal generated by the signal generation unit as an input signal to a driving circuit to extend the piezoelectric element.
