Abstract

The invention concerns a Stirling cooling arrangement (1) with a driving unit (2) that generates periodically changing gas pressures, and a displacer unit (4) connected to the driving unit (2) and comprising a displacer (15) that is movable in a displacer housing (6) along a displacer axis (16). It is endeavoured to achieve a good efficiency. For this purpose, the displacer (15) comprises a body (20) of a plastic material that is provided with a metal ring (22), whose outer diameter is larger than the outer diameter of the body (20).
