1. A power transmission apparatus for a compression stage in a compressor for loose packed materials the compressor having a first compression stage and a second compression stage, said power transmission apparatus comprising:

  • a compressor piston of the second compressor stage, said compressor piston being shaped to extend about at least a portion of the first compression stage and to be reciprocally movable with respect thereto;

    said compressor piston having a first end and a second end;

    said first end of said compressor piston being an output end thereof, and being shaped to conform to a co-operating mating cylinder within which said compressor piston is mounted to reciprocate in a longitudinal direction;

    said second end being distant from said first end;

    said power transmission apparatus having a movable power input interface at which motive force is applied to said compressor piston;

    said power input interface having a fixed position relative to said first end of said compressor piston;

    said power transmission apparatus having a stationary reaction datum, said compressor piston being movable in longitudinal reciprocation relative to said stationary reaction datum;

    said power input interface being driven along a single degree of freedom of motion relative to said stationary reaction datum.
