First and second pistons that both move along the central axis, wherein the first piston and second piston have similar mass. The first and second pistons are propelled by magnetic forces in an oscillating motion with a 180 degree phase difference between the first and second pistons.
1 . An apparatus for pumping and compressing fluids, comprising:
a compression chamber, the chamber containing at least one inlet and one outlet, and a plurality of open volumes created by an inner surface of the compression chamber; and
a plurality of pistons within the compression chamber, each piston containing a body with at least a first diametrically polarized magnet centered in the body, such that the polarities attract or repel depending on the relative position of the magnet;
a plurality of flux paths centered around each of the pistons, each flux path containing a coil to act as a polarizing motor stator.
2 . The apparatus of claim 1 wherein the compression chamber is made of glass.
3 . The apparatus of claim 1 wherein each piston body is comprised of graphite.
4 . The apparatus of claim 1 further comprising:
an additional magnet centered within the compression chamber between two of the plurality of pistons.
5 . The apparatus of claim 4 wherein the compression chamber contains a magnet on a first end of the compression chamber.
6 . The apparatus of claim 5 wherein each piston comprises:
a second and a third magnet on respective first and second outer sides of the piston body.
7 . The apparatus of claim 5 wherein each of the plurality of pistons is separated from an inner surface of the compression chamber by an air bearing surface on the respective piston.
8 . A gaseous fluid pump comprising:
at least one cylinder having a wall defining an inner volume and containing a central axis;
a first piston and a second piston that both move along the central axis, wherein the first piston and second piston have similar mass;
wherein the first and second pistons are propelled by magnetic forces in an oscillating motion with a 180 degree phase difference between the first and second pistons.
9 . The pump of claim 8 wherein the first and second pistons and the cylinder have similar thermal coefficient coefficients.
10 . The pump of claim 9 wherein the first and second pistons are supported in the inner volume of the cylinder with gaseous bearings.

15 . A gaseous fluid pump comprising:
a cylinder with first and second ends connected by a wall to define an inner volume, wherein the first and second ends each contain a respective first and second permanent magnet;
at least one piston capable of travel within the cylinder, the piston comprising a first end and a second end, and at least one magnet;
wherein the magnetic poles of the first and second permanent magnets face like poles of the piston magnet to produce a repelling spring effect to push the piston towards the center of the cylinder.
16 . The pump of claim 15 wherein the first and second permanent magnets and piston form an oscillating mass and spring system with a specific oscillation frequency for the piston.
17 . The pump of claim 15 wherein the piston magnet and first and second permanent magnets are circular in cross-section and magnetized across the diameter of the cross-section.
