摘要： A two-stage hybrid cryocooler (20) includes a first-stage Stirling expander (22) having a first-stage regenerator (24) having a first-stage-regenerator inlet (26) a nd a first-stage-regenerator outlet (28), and a second-stage pulse tube expander (32). The second-stage pulse tube expander (32) includes a second-stage regenerator (34) having a second-stage regenerator inlet (36) in gaseous communication with the first-stage regenerator outlet (28), and a second-stage regenerator outlet (40), and a pulse tube (42) having a pulse-tube inlet (44) in gaseous communication with the second-stage regenerator outlet (40), and a pulse-tube outlet (48). The second-stage regenerator (34) and the pulse tube (42) together provide a first gas-flow path (43) between the first-stage regenerator (24) and the pulse-tube outlet (48). A pulse tube pressure drop structure (50) has a pulse-tube-pressure-drop inlet in gaseous communication with the pulse-tube outlet (48), and a pulse-tube pressure-drop outlet, and a gas volume is in gaseous communication with the pulse-tube pressure-drop outlet. A gas flow shunt (60) provides gaseous communication between the first-stage regenerator (24) and the pulse-tube outlet (48). The gas flow shunt (60) provides a second gas-flow path (62) between the first-stage regenerator (24) and the pulse-tube outlet (48).

摘要： A regenerative refrigeration system (10) includes one or more control devices (20, 22) that utilize micro electro mechanical systems (MEMS) technology. Such MEMS devices may be small in size, on a scale such that it can be introduced into a refrigeration system, such as a cryocooler, without appreciably affecting the size or mass of the refrigeration system. Through the use of MEMS devices, dynamic control of the system may be achieved without need for disassembly of the system or making the system bulky. Suitable regenerative refrigeration systems for use with the MEMS devices include pulse tube coolers, Stirling coolers, and Gifford-McMahon coolers.

摘要： A cryogenic refrigeration system (20) includes an expansion nozzle (31) having a high-pressure nozzle inlet (32) and a low-pressure nozzle outlet (33), and a compressor (24) having a compression device (53), such as a pair of opposing pistons (54), operable to compress gas within a compression volume (56). The compression volume (56) has an inlet port (74) and an outlet port (76). A flapper inlet valve (78) has an inlet valve inlet (80), and an inlet valve outlet (82) in gaseous communication with the inlet port (74) of the compression volume (56). The inlet valve (78) opens when a gaseous pressure at the inlet valve inlet (80) is sufficiently greater than a gaseous pressure in the compression volume (56) to overcome a spring force of the flapper inlet valve (78). A flapper outlet valve (88) has an outlet valve inlet (90) in gaseous communication with the outlet port (76) of the compression volume (56), and an outlet valve outlet (92) in gaseous communication with the nozzle inlet (32). The outlet valve (88) opens when a gaseous pressure in the compression volume (56) is greater than a gaseous pressure at the outlet valve outlet (92) to overcome a spring force of the flapper outlet valve (88). A drive motor (22) is in driving mechanical communication with the compression pistons (54). The compression volume (56) is hermetically isolated from the drive motor (22).
