An Ericsson cycle machine is disclosed which can be used for refrigeration, liquefaction of nitrogen or as an engine. The invention includes a liquid ring compressor linked to a liquid ring expander by a gas loop that includes a recuperator. As a refrigeration unit, the liquid ring in the compressor is channeled through a heat exchanger to reject waste heat and liquid is tapped from the expander liquid ring and used as a refrigerant.
