Case that the ejection time of the gas increases even with the gas supply can be reliably and provides excellent responsiveness of the piezoelectric valve when modified. Piezoelectric valves from accepting the compressed gas supplied from the external gas pressure chamber, and the pressure of the gas chamber as a piezoelectric valve having a gas outlet for discharging the compressed gas, is arranged in the gas pressure chamber to the gas discharge and valve means for opening and closing, and the piezoelectric element for generating a driving force necessary for the operation of the valve body as a displacement, by expanding a displacement of the piezoelectric element made of a displacement increasing mechanism which acts on the valve body, pre-pulse and main pulse having parts of the signal generator which generates a signal, to the signal generated by the unit that signals occurring on the input signal to the drive circuit applies a drive voltage to the piezoelectric element, followed by elongation the piezoelectric elements modified drive the valve body provided with a drive means.
