ABSTRACT:
A cryogenic refrigerator is disclosed which features a novel combination of displacer and refrigerant flow control means. The displacer comprises two sections, with one displacer section being arranged to vary the volume of a first chamber as the displacer undergoes reciprocating motion, and the other displacer section being arranged to vary the volume of a second chamber during the same motion. The first and second chambers, which serve as working chambers from the standpoint of achieving refrigeration, are connected by first and second heat exchangers and first and second thermal regenerators respectively and a flow control means to high and low pressure sources of refrigerant fluid. The flow control means comprises a slide valve which is movable by the displacer and coacts therewith to control movement of refrigerant into and out of the first and second working chambers as their volumes change with movement of the displacer.
