Low-temperature storage tank interface

The gas inlet is used for pressurization, the pump return inlet is connected to the cryopump, and the vent outlet is used for pressure relief
What was said upstairs is correct; another possibility for the gas inlet is that it serves as a backup gas inlet, which is used when the amount of gas available is low.
Well explained; I just came across this new content, thanks!
