摘要： The present invention relates to a Stirling free piston cryocooler (1) in which the drive assembly is arranged in an in-line opposed piston arrangement. The displacer piston assembly (11) is nested within the power piston assembly (10). In one embodiment the thermodynamic assembly is connected to the drive mechanism in a tee arrangement so that the opposed cryocooler pistons share a common expansion space (24). In another embodiment the thermodynamic assembly is connected to the drive mechanism in a double split tee arrangement with the thermodynamic components remotely located from the expansion (103) and compression spaces (104) and connected thereto by flexible tubes (105, 106).

摘要： A linear motor compressor within a cryogenic refrigerator wherein the compressor space, within which a gaseous fluid is alternately compressed and expanded, is formed by a stationary piston (11) and a reciprocating armature (10) that is concentric about the piston. The armature is supported along a clearance seal with the stationary piston. An axial bore (14) along the stationary piston conveys gaseous fluid from the compression space (24) to a displacer within the cold finger of the cryogenic refrigerator. An isolator for reducing transmission into and out of the compressor comprising a dynamic absorber (40) and flat springs (61, 71) mounted with a damping material (95, 96) between the compressor and a mounting frame. A sensor (80) for detecting the position of the armature utilizes a target magnet (81) whose magnetic flux lines are decoupled from the flux lines generated about the coil.

摘要： A linear drive motor of a cryogenic refrigerator, where a reciprocating armature (10) which alternately compresses and expands a gaseous fluid in a thermodynamic cycle, is supported at both ends by flexure supports (110, 130). The armature has a clearance seal (150) with a stationary piston (11) attached at one end to the armature housing by a flexible stem (11B) to minimize cross-bearing loads between the armature and the stationary piston along the clearance seal.

摘要： A cryogenic refrigerator includes a displacer that is reciprocably mounted within a cylinder; a spool valve that is connected to the compressor and performs switching between an intake mode where a high-pressure refrigerant gas is supplied from the compressor to the cylinder and an exhaust mode where a low-pressure refrigerant gas within the cylinder is made to flow back to the compressor; and a drive unit that drives the spool valve. The spool valve has a valve body, and a drive rod that moves relative to the valve body and is integrated with the spool. The drive unit performs driving so that the magnitude of a speed when the drive rod moves from a top dead center to a bottom dead center is different from the magnitude of a speed when the drive rod moves from the bottom dead center to the top dead center, at the same displacement position.

摘要： An active gas regenerative refrigerator includes a plurality of compressor-expander units, each having a hermetic cylinder with a drive piston configured to be driven reciprocally therein, and a quantity of working fluid in each end of the cylinder. A piston seal in a central portion of the cylinder prevents passage of the working fluid between ends of the cylinder. Movement of the piston to a first extreme results in radial compression of one of the quantities of working fluid in a cylindrical gap formed between one end of the piston and an inner surface of the cylinder, while the other quantity is expanded in the opposite end of the cylinder. The piston includes a plurality of magnets arranged in pairs, with magnets of each pair positioned with like-poles facing each other. A piston drive is configured to couple with transverse magnetic flux regions formed by the magnets.

摘要： A thermal storage container is coupled to a pump for circulating cooled liquid from the thermal storage container in at least one of two circuits. One circuit includes a heat exchanger coupled to the fresh food evaporator for assisting in cooling the fresh food section of the refrigerator or for chilling the liquid. Another circuit includes a sub-cooler between the condenser and the evaporator for cooling the output from the condenser before entering the evaporator, herby increasing the efficiency of the system. A three-way valve is coupled from the output pump to couple the stored coolant selectively to one or the other or both of the coolant circuits.

摘要： A helium management control system for controlling the helium refrigerant supply from a common manifold supplies cryogenic refrigerators with an appropriate helium supply. The system employs sensors to monitor and regulate the overall refrigerant supply. An appropriate supply of helium is distributed to each cryopump. If the total refrigeration supply exceeds the demand, or consumption, excess refrigerant is directed to cryogenic refrigerators which can utilize the excess helium to complete a current cooling function more quickly. If the total refrigeration demand exceeds the total refrigeration supply, the refrigerant supply to some or all of the cryogenic refrigerators will be reduced accordingly so that detrimental or slowing effects are minimized based upon the current cooling function.

摘要： A system includes a device, a support structure, and a flexure bearing configured to connect the device to the support structure. The flexure bearing includes an outer hub and an inner hub, where the hubs are configured to be secured to the support structure and to the device. The flexure bearing also includes multiple sets of flexure arms connecting the outer and inner hubs. Each set of flexure arms includes symmetric flexure arms. The flexure bearing could include three sets of flexure arms positioned radially around a central axis of the flexure bearing and having a spacing of about 120°. Each flexure arm can follow a substantially curved path between the outer hub and the inner hub. The symmetric flexure arms in each set can be configured such that twisting of one flexure arm in one set is substantially counteracted by twisting of another flexure arm in that set.

摘要： An integrated Stirling refrigerator is composed of two parts: a compressor and an expander. The compressor is composed of a shell (1), a piston (4), a leaf spring (8), a magnet (9), a coil (10), a bracket (14) and a support shelf (15). The shell (1) of the compressor includes two cylinders (11, 12), one of which is set inside the other to form a compression chamber (3). The piston (4) is connected with the leaf spring (8). The coil (10) is fixed between the inside of the shell (1) and the bracket (14), and the magnet (9) is fixed between the bracket (14) and the support shelf (15), wherein the bracket (14) and the support shelf (15) are respectively connected with the shell (1). The inside of the expander is divided into two chambers by a small piston and a regenerator (7) fixed together, that is, an expansion chamber (6) and a pneumatic chamber, and a cylindrical spring (16) is provided on the bottom of the expander. The center of the compressor is designed as a groove, and the expander is inserted into the groove of the compressor. There is a small hole designed on the bottom of the expander, which is communicated with the compression chamber (3) of the compressor. The Stirling refrigerator has the advantages of compact structure and small volume, and hence it can be widely used.
