Abstract (en)
The helium gas compressing apparatus of this invention is constructed in such a manner that the oil separator (5) in the high-pressure gas passage (4) is connected to the low-pressure gas passage (2); that the oil return path having the first (30) and second (31) branch paths is provided between the high- and low-pressure gas passages; that the capillary tube (6) is installed in one of the two branch paths; and that the adjust valve (32) is installed in the other branch path to adjust the pressure difference between the supply gas in the high-pressure gas passage (4) and the return gas in the low-pressure gas passage (2). Because of this construction, the adjust valve (32) can be manipulated from outside to make fine adjustments on the pressure difference or change it to a desired value with ease even during operation of the apparatus, thereby adjusting the refrigerating capability of the helium refrigerating machine and the power consumption of the helium gas compressing apparatus.
