Abstract
A cryogenic refrigerator is disclosed having a displacer with a regenerator therein. The regenerator opens at one end to a warm volume and at the other end to a cold volume. The opening at the cold volume includes an end hole and a plurality of radial holes. The radial holes serve as secondary passageways should the end hole become blocked with contaminants. The life of the cryogenic refrigerator is thereby greatly enchanced.
