Patent ID: 8015831

Claim:
A Stirling cryocooler comprising: a magnetic circuit; a compressor coil disposed within the magnetic field of said circuit, said coil being adapted to translate along a first longitudinal axis; a first flexure stack coupled to one side of said compressor coil; a second flexure stack disposed on an opposing side of said compressor coil such that said compressor coil is positioned between said first and second flexure stacks; a mechanical coupling between said first flexure stack and said second flexure stack; a third flexure stack and a fourth flexure stack longitudinally separated from each other so as to contain the first and second flexure stacks therebetween; a displacer coil adapted to translate along said first longitudinal axis; wherein said displacer coil is disposed between said first and said second flexure stacks; wherein the fourth flexure stack is coupled to said displacer coil at a first end thereof; and wherein the third flexure stack is disposed at a second end of said displacer coil such that said displacer coil is positioned between said third and fourth flexure stacks.
