内圧負荷装置。 An oscillator that oscillates the internal pressure waveform applied to the test piece as an electrical signal, a pressure cell that detects the internal pressure of the test piece, a comparator that compares the signal waveform from the oscillator with the internal pressure, and a servo control system that controls the gas pressure supplied to the test piece. The comparator is equipped with a gas intensifier chamber that adjusts or decreases the pressure via a valve, a gas source, a solenoid valve connected to the gas source, and a control device that controls opening and closing of the solenoid valve, and the comparator is configured to receive a signal from the oscillator. Compare the signal waveform and the internal pressure, and if the deviation value is small, send a command signal to control the advance or retreat of the servo valve, and if the deviation value is large, send a command signal to the control device to open or close the solenoid valve. An internal pressure loading device characterized by:
