Patent
·
OSTI ID:5680574
A method and apparatus for producing refrigeration without loss of refrigeration or introduction of magnetic disturbance when using a displacer-expander type cryogenic refrigerator pneumatically actuated by a rotary valve coupled directly to a motor, the displacer-expander, rotary valve and motor being a single unit, by removing the motor from the unit and driving the valve by means of a flexible shaft. The flexible shaft can be disposed within a fluid conduit used to deliver high-pressure fluid to said refrigerator.
