ABSTRACT:
Refrigeration systems of the type including first and second communicating, sealed, cylindrical, vessels having respective first and second piston-like elements reciprocating axially therein are characterized by having the vessels positioned in a line along a single axis and having a rod or shaft extending along the axis through a sliding seal for connecting the piston-like elements. A coupling for connecting the rod with one of the piston-like elements allows "lost" axial motion of the rod, without a corresponding motion of the attached piston, over a first portion of the range of axial travel of the rod in both directions. An intercommunicating line is also included for intercommunicating appropriate ends of the elongated vessels.
Such refrigeration systems can operate in various modes of operation, such as stirling-cycle modes of operation, and Vuilleumier-cycle modes of operation.
