Claims

[Scope of utility model registration request]

In a gas refrigerator drive device that utilizes the principle of a Stirling cycle engine, an oscillator is set around a frequency that has a natural frequency at which the gas refrigerator can easily operate, and a linear a power amplifier that can amplify the output of the power amplifier, a coil wound around a magnetic material so that the output of the power amplifier can be driven by current, a permanent magnet placed on the side facing the magnetic material, and a piston directly connected to the permanent magnet. A gas refrigerator characterized in that it is driven according to the frequency of an oscillator and has the ability to create a low-temperature space by thermodynamically cycling the medium in the piston.
