The development of a highly reliable, long-life cryogenic refrigerator for space vehicle application is currently in progress. The program objective is to demonstrate feasibility of the refrigeration system for 1–2 W capacity at refrigeration temperatures of 3.6° and 4.2°K. This paper describes one of the major components of the refrigerator, a four-stage compressor of the regenerative type driven by an integral electric motor. For reasons of system simplicity, performance and reliability, only self-acting (hydrodynamic) gas bearings are used in the compressor.
