✦ Synopsis
To transfer He II m space, the supply tank must be drained at low gravtty Conventtonal capillary dewces such as the gallery system make use of the capillary retentton capability of the screens for fluid management L=qutd hehum ts collected into gallery channels and then conveyed to the downstream fountain effect pump (FEP) or mechamcal pump In this Paper, a new fluid management dewce is proposed The screens along the gallery channels are replaced by porous plugs which are responsible for both the flutd retention and pumping (by mechamcal effect) of He II No downstream pump ts needed The plugs m contact with hqutd hehum on both stdes act as FEPs, and plugs exposed to vapour on one side behave as vapour-hqu=d phase separators (VLPSs) The total net transfer rate of He II into the recewmg tank =s the mass flow rate through the FEP minus the hqu=d loss from the VLPS plugs The performance of the integrated FEP device (IFD) was analysed The posstblllty of hquid breakthrough m the IFD was studied The IFD ts a very promising system for the fluid management of He II at low grawty
