Development of a linear-motor resonant-piston compressor LMRPC for helium cryogenic refrigerators is under consideration by the U.S. Navy. A critical component of the LMRPC is the gas spring assembly used to obtain 60 hz resonance of the reciprocating compressor parts. Because of the size of the compressor, and the high level of compressor efficiency desired by the Navy, design of the gas spring is particularly critical with respect to minimizing gas spring leakage and thermal losses. The primary objective of the reported design and test program was to determine if a satisfactory gas spring can be developed for use in a prototype helium LMRPC. A further objective was to demonstrate that gas-lubricated bearings can be used to provide wear-free, contamination-free support of the reciprocating assembly of the LMRPC. Modified author abstract
