Abstract
Cryogenic refrigeration apparatus characterized as an in-line Stirling engine wherein the piston and displacer are driven by means mechanically linking them to move in phase along a common axis. The flow of fluid between the compressor and expander is controlled by fluid flow control means, actuated by the motion of the driving means, which makes possible the achievement of essentially constant volume heat removal.
