The invention, a high-pressure, reciprocating, gas compressor, employs labyrinths to create gas sealing, annular, air dams between the piston and cylinder bore, and piston rod and an aperture in an end wall or closure of the cylinder through which the rod translates, and active magnetic bearings to maintain the piston and rod at their centroids, equally and minutely spaced, fully thereabout, within the bore and aperture. Too, the drive mechanism, a scotch yoke arrangement, has further, active magnetic bearings, to centralize a drive shaft in its housing, and to effect a non-contacting travel of the drive shaft's offset crank, which translates the piston rod, within the yoke.
