摘要： A cryogenic refrigerating machine adopting the Gifford MacMahon (GM) cycle wherein a rotary valve device (RV) for controlling the supply and discharge of refrigerant gas to/from a refrigerating machine (2) is rotated forwardly and/or reversely by means of reversibly motor (15), wherein a cooling mode operation for generating cold heat by virtue of adiabatic expansion is performed during forward rotation, while a temperature increasing mode operation for generating heat by virtue of adiabatic compression is performed during reverse rotation, and wherein the opening and closing timing of the rotary valve device (RV) relative to the reciprocating movement of displacers (3a, 3b) during forward reverse rotation is made different from that during reverse rotation so that optimum efficiency is obtained during the cooling mode and heating mode operations, respectively. As a result, it is possible to reduce time needed to heat the cooling portion in a cryogenic state of a room temperature without any particular equipment.

摘要： The leakage of the coolant through a sealing member at ultra-low temperatures is minimized. The sealing member (32) is made of an unsaturated polyester PTFE whose filling ratio of unsaturated polyester is 20 % - 35 %. The end portion (35) of the outer circumferential wall (32a) has a plurality of slits (36) that extend in the axial direction and pierce through the wall in the radial direction. The synergistic effect of the use of a material with a small thermal expansion coefficient and the reduction in overall shrinkage of the outer circumferential wall (32a) in the radial direction resulting from its shape enhances the sealing performance and minimizes the leakage at ultra-low temperatures, thus preventing degradation of the refrigerating capability.

摘要： The invention relates to a process and a device for utilising the heat in the exhaust gas from the combustion chamber of a thermogenic and cryogenic machine operating on a regenerative gas circuit process by preheating the air of combustion supplied to the combustion chamber, in which the process gas forced out of the hot working volume or fed into it passes through a regenerator fitted inside a pressure-proof housing in the region of the hot piston. In order effectively to utilise the exhaust gas heat without additional equipment complications and without insulating the machine in the region of the hot regenerator while maintaining the temperature profile needed to run the regenerator, the air of combustion is utilised to cool the lower part of the pressure vessel wall surrounding the lower part of the regenerator, this cooling corresponding to the lower part of the regenerator's temperature profile. To maintain the upper part of the temperature profile required for regenerator operation, exhaust gas is caused to flow around the upper part of the pressure vessel wall surrounding the regenerator, whereby at the same time heat is extracted from the exhaust gas in this region by the air of combustion flowing in counterflow on the outside of the exhaust gas stream.

摘要： A Gifford-McMahon cryorefrigerator is modified by using opposed sub-displacers which are sinusoidally reciprocated in opposite directions with respect to one another such that the force vectors of inertia created by the movement of the sub-displacers are cancelled out. The cancelling out of the force vectors should substantially reduce adverse effects associated with displacer banging.

摘要： A method for detecting the absence of a pressure differential across a cryogenic refrigerator (12) includes the following steps. At least one measurement of load in the refrigerator (12) is taken during both a warmstroke and a coldstroke of a refrigeration cycle. These measurements are then compared to determine whether the differential load across the cryogenic refrigerator (12) has been lost. A system for performing this method includes a compressor (14) that circulates compressed gas through a compressed gas line routed through a cryogenic refrigerator (12). Within the refrigerator (12), a displacer (207, 209) is driven through a refrigeration cycle by a motor (218). A means for measuring the load on the motor (218) is provided, and an electronic module (20) monitors the load measurements to detect a loss of differential pressure across the refrigerator (12) by comparing the load on the motor (218) during the warmstroke to the load on the motor (218) during the coldstroke.

摘要： A gas-pressure driven type cryogenic refrigerator in which a cylinder (2) is partitioned into a lower pressure chamber (20), an upper pressure chamber and expansion chambers (30, 31) by a slack piston (17) and a displacer (22) connected thereto. A rotary valve (35) is adapted to set up alternately a high-pressure open-valve state that high-pressure helium gas is supplied into the upper pressure chamber (29) and the expansion chambers (30, 31) and a low-pressure open-valve state that helium gas is discharged from the upper pressure chamber (29) and the expansion chambers (30, 31), whereby the slack piston (17) is driven by virtue of the difference in gas pressure between the upper and lower chanbers (29, 20) to thereby reciprocate the displacer (22). The reciprocation produces cryogenic coldness. The time ratio of the low-pressure open-valve state is set at 55-65 %, higher than that of the high-pressure open-valve state, thereby improving the capability of the refrigerator.

Volume regulating means (8a) is provided for changing a volume in an intermediate-temperature space (35) in the low-temperature-side rod (33). In addition, volume control means (9a) is provided for detecting the number of revolutions of a crankshaft (42) on the coupling mechanism (4), calculating a volume in the intermediate-temperature space (35), which volume corresponds to the above number of revolutions, and controlling the volume regulating means (8a) such that the volume in the intermediate-temperature space (35) eqals the calculated volume. Thus an improvement of a net COP (coefficient of performance) is achieved.
