背圧を得るようにしたことを特徴とする電・空変換器。It consists of a circuit that receives an input signal, a pulse voltage generator that periodically generates a pulse signal voltage whose pulse width changes depending on the input signal from the input signal supplied circuit, and an electrostrictive element. a nozzle flapper to which the pulse voltage is applied to the electrostrictive element; a nozzle disposed opposite to the vibrating part of the nozzle flapper to receive supply pressure and derive back pressure; and a pilot valve to convert this back pressure into output pressure. The receiver includes a feedback circuit that converts the output pressure into an electric signal and balances the input signal with the input signal supplied circuit, and adjusts the frequency of the pulse signal voltage of the pulse voltage generator to the mechanical output of the electrostrictive element. The fully closed time ratio of the nozzle is set to be approximately equal to the target resonance frequency, and the fully closed time ratio of the nozzle is changed in response to changes in the pulse width of the pulse signal due to changes in the input signal, thereby obtaining back pressure in accordance with the input signal.
