Abstract:
Provided is an apparatus for connecting two sub-flow systems (e. g. airplane fuel tanks) and conveying a fluid between the two sub-systems using a pressured balanced transfer tube, particularly when there are large radial and axial movements or offsets between the sub-systems. Unlike conventional fluid transfer systems, the present apparatus allows for the pressure in the transfer tube to be balanced to internalize the pressure forces and prevent the exertion of pressure forces on the sub-systems connected to the transfer tube.
