Abstract

PURPOSE:To simplify transfer of liquid helium in such a way that pipeline is drawn out of an ultralow temperature liquid pump body to its cold part, and a pressure means and a decompression means are provided at the cold temperature end of the pipeline. CONSTITUTION:A narrow pipeline 9a is drawn out of the body 3 of a liquid helium pump to the outside of a liquid helium reservoir 1, namely, the cold part. One end of the cold part side of the narrow pipeline 9a is connected to one end of a cylinder 10. The narrow pipeline 9a is used for pressuring and decompression. The other end of the cylinder 10 is connected through the narrow pipeline 9b to a valve 11 for pressuring and decompression, and the valve 11 is supplied with helium through a pressuring source 12, so that transfer of liquid helium can be simplified.
