Abstract
In one example embodiment, a fluid transfer coupling arrangement includes a hollow shaft that is arranged in a housing and rotatable about an axis. The hollow shaft is provided by a wall having radially spaced interior and exterior surfaces. A first passage extends through the wall and is configured to communicate fluid between the interior and exterior surfaces. A fluid coupling is located mid-shaft, sealed about the exterior surface, and aligns to the first passage. The fluid coupling provides a second passage that is in fluid communication with the first passage. The fluid coupling includes a locating feature configured to permit radial movement of the fluid coupling relative to the housing and allowing the fluid coupling to track subtle shaft movements.
