ABSTRACT:
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.
