The present invention generally relates to cryogenic refrigerator and more particularly, the cryogenic refrigerator compressor assembly procedure and to means for supporting piston for use in such a cryogenic refrigerator. <??>This invention solves the above-mentioned drawbacks by avoiding the radial movements of the piston. An object of this invention is the assembly procedure of a cooler compressor comprising the following steps: At least one piston is coated by a material, Each piston is placed in the cylinder, The temperature is raised up until a predetermined temperature so as the piston and/or its coat expanse to occupy all the cylinder, Each piston is fixed in the cylinder in this position, The temperature returns to ambient temperature. <??>Another object of this invention is the cooler compressor piston spring comprising two flexure bearings separated by a gap connected together by a first and a outer rings. <IMAGE> |
