摘要： The invention relates to a device for the recondensation by means of a cryogenerator of low-boiling gases of the gas evaporating from a liquid gas container. The inventive device comprises one or at least two continuous cooling stages, the so-called cold top. Every stage is a pulse tube cooler whose heat transfer between the regenerator and the pertaining pulse tube is embedded in an exposed cold surface. The entire cold top is flanged only on the outer recipient of the device and projects into the interior in the neck tube of the device. The last cold surface of the cold top is located at the end of the neck tube and is exposed in the vapor room above the liquid gas cold bath. The other cold surfaces are opposite a heat transfer ring mounted on the neck tube. The respective opposite front faces engage with each other without contacting each other in any place while forming a gap so that a free passage is guaranteed from the vapor room via the liquid gas bath to the flange of the cold top in the neck tube. The two components regenerator, pulse tube of every pulsed tube cooling stage are covered with a heat shield that can be a poorly thermoconductive covering only resting thereon or an annular vacuum chamber whose outer wall contacts the sheathing component only in certain positions or only across short distances in a linear manner.
