Abstract
A peristaltic compressor suitable for relaxation-free compression of polarized gas including a pumping rotor driven by a motor provided with a plurality of rollers, and at least a tube, wherein the rotor and the tube(s) is(are) placed in a depressurized chamber having a lower pressure than atmospheric pressure, and wherein the motor is formed by at least one tube fed by a pressurized fluid, driving into rotation a peristaltic rotor provided with rollers, coupled with the pumping rotor.
