ABSTRACT:
A cryogenic refrigerator and more particularly, the cryogenic refrigerator compressor assembly procedure and to a mechanism for supporting piston for use in such a cryogenic refrigerator is described. Embodiments of the present invention solve the above-mentioned drawbacks by avoiding the radial movements of the piston. The assembly procedure of a cooler compressor comprises coating at least one piston by a material, placing each piston in the cylinder, raising the temperature up until a predetermined temperature so as the piston and/or its coat expands to occupy all the cylinder, fixing each piston in the cylinder in this position until the temperature returns to ambient temperature. Another object of this invention is the cooler compressor piston spring having two flexure bearings separated by a gap connected together by a first and an outer ring.
