摘要： A cryogenic refrigerator is disclosed which essentially comprises a cylinder, a displacer slidably mounted within the cylinder so as to form a chamber whose volume varies with movement of the displacer, drive means mechanically connected to the displacer for causing the displacer to reciprocate, and valve means for continuous flow of a refrigerant fluid into and out of the chamber, the valve means being operable by said displacer so as to (a) cause high pressure refrigerant fluid to enter the chamber during a first selected portion of the displacer's operating stroke and (b) exhaust low pressure fluid from the same chamber during a second selected portion of the displacer's operating stroke.

摘要： 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.

摘要： A gas-driven fluid flow control valve capable of responding to a signal to alter the direction of fluid flow therethrough. When the valve is interposed between high- and low-pressure fluid reservoirs on one side and a cryogenic refrigerator requiring the supplying of high-pressure fluid and the discharging of low-pressure fluid on the other side, it may be used to reverse the flow of fluid through the refrigerator to switch it from a cooling to a warming mode. The incorporation of such a refrigerator into a cryopump in conjunction with the gas-driven valve makes it possible to rapidly warm up the condensing and adsorbing surfaces of the cryopump thus reducing the regeneration cycle of the cryopump from several hours to about 30 to 35 minutes.

摘要： A stacked disc heat exchanger for a refrigerator cold finger includes a plurality of discs positioned within a cold finger cylinder and clamped to a cylinder end plate. Radial gas flow passages between the plates join inner and outer longitudinal gas flow passages. The radial passages provide a large surface area for contacting refrigeration gas and effecting efficient heat exchange with a load attached to the end plate. In a preferred embodiment the radial passages are flat grooves in the faces of discs. The stack of discs provides ease in assembly and great flexibility in designing the heat exchanger for particular applications.

摘要： In a cryogenic refrigerator, a refrigerant is circulated in a fluid flow path between first and second chambers by the movement of a displacer means. A slide is connected to the displacer means and reciprocated by a motor. The slide has an axial passage communicating the first and second chambers. The slide has a piston for varying the volume of gas in a third chamber during its reciprocation. The need for a separate compressor is eliminated.

摘要： A method and apparatus for controlling the reciprocal movement of a free piston, gas-driven displacer in a cooling engine are disclosed. A bi-directional magnetic "detent" is established for the displacer at both the top dead center and bottom dead center portions of the cooling cycle. Each bi-directional magnetic "detent" provides a magnetic snubbing force to limit overshooting of the displacer in one direction and a magnetic retention force to hold the displacer from moving in the other direction until a pre-determined pressure differential is established across the displacer's drive piston. The magnetic "detents" are formed by means of a three pole double magnet with a single core or alternatively, by a two pole single magnet with a double core. The magnetic snubbing and retention forces can be made equal or unequal in magnitude either through the selection of permanent magnet(s) or core configuration(s) or by controlling the field strength of electro-magnets.
