A compressor or turbine type rotary machine for compressing or expanding a dangerous gas, e.g. a gas that is toxic or explosive, comprises a closed enclosure formed outside the stator around a shaft passage receiving the shaft of the rotor, the enclosure being delimited by a bell and being filled with a liquid under pressure, a wet type mechanical seal being disposed between the rotor shaft and the stator, inside the stator. The liquid contained in the enclosure is put under pressure, and a magnetic coupling is provided to link the rotor shaft to an outside shaft. The invention makes it possible to prevent any leakage of dangerous gas from the inside to the outside of the rotary machine.
