Abstract
A transfer tube system includes a transfer tube, a spring, a pair of opposing seats, and a pair of end assemblies that provide independent axial spring loading of the opposing seats. The spring loading assures continuous sealing contact regardless of dynamic loading, dimensional stack-up, or geometry change resulting from interfaced wear. The transfer tube end assemblies include a spherical or conical seat for mating with the transfer tube. Particularly, the transfer tube has spherical ends for seating in the transfer tube end assembly seats. The conical/spherical seats permit angular motion of interfacing components without lift off and therefore assures minimal leakage.
