Cryogenic Stirling refrigerator with a pneumatic expander
11209192 · 2021-12-28 · ·

A split Stirling cryogenic refrigerator device may include a resonant pneumatic expander comprising a resonant displacer assembly supported by a spring and configured to slide back and forth along a longitudinal axis within a housing of the resonant pneumatic expander, the resonant displacer assembly comprising a tubular displacer containing a regenerator and coupled to a sealing piston, and a driving piston coupled to the sealing piston by an elongated radially compliant and axially rigid connecting member.
