Abstract

A compression apparatus for compressing a fluid, the apparatus having a frame and a motor mounted to the frame, the improvement comprising a drive mechanism installed on the frame so as to be driven by the motor and at least one piston-cylinder unit operably connected to the drive mechanism, the piston-cylinder unit having a cylinder, a piston slidably installed within the cylinder, and a piston rod interconnecting the piston and the drive mechanism so as to shift the piston up and down within the cylinder.
