This invention involves a balanced single stage linear compressor with an oil-filled cavity to equalize pressure on the diaphragm. The oil-filled cavity further includes a volume compensating gas chamber and a passive balancer. A balance mass is attached to the bellows and is supported by a fluid film bearing. The balance mass is arranged so that the oil displaced by the piston acts on the mass and displaces the mass in a direction opposite to that of the piston thereby balancing the apparatus.

A magnetic bearing rotating structure includes a rotor magnetically supported in a housing by a magnetic bearing. A back-up bearing arrangement is used to resist impact on the rotor, including a fixed bumper bearing for resisting a sudden impact, and an auxiliary bearing for rotatably supporting the rotor while the magnetic bearing resumes operation.

A ceramic liner for use in an external heat or combustion system for use with a Stirling engine and the like having a housing containing a heater space whereby the ceramic liner is disposed in the heater space and defines a combustion chamber within the liner mounted to the housing via a biasing arrangement so as to isolate the lining from vibrations in the housing.
