摘要： The present invention relates to valved cryogenic refrigerators, in particular, Gifford McMahon (GM) refrigerators, and GM type pulse tube refrigerators where gas is cycled between high and low pressures by a valve mechanism that connects to an expander. Input power is reduced by use of a buffer volume which stores gas that flows to and from the warm end of the regenerator through a valve that opens and closes during the periods when the main supply and return valves are closed and is closed when the main supply and return valves are open.

摘要： A rotary valve of a multivalve type pulse tube refrigerator includes: a stationary seat; a rotary disk to change a coolant path by rotating while surface-contacting with a face of the stationary seat; a plurality of first ports provided in the face of the stationary seat to supply a high-pressure coolant to a regenerator and exhaust a low-pressure coolant from the regenerator; and a plurality of second ports provided in the face of the stationary seat to supply a high-pressure coolant to a pulse tube and exhaust a low-pressure coolant from the pulse tube. The first ports are arranged in a first circular track area in rotation symmetry with respect to the center of the face. The second ports are arranged in a second circular track area in rotation symmetry with respect to the center of the face.
