    摘要: 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.

    摘要: A dual-inlet gear pump includes a drive gear and a driven gear. The invention utilizes the discovery that the drive gear will typically move a higher flow volume than does the driven gear, particularly when the fluid being moved is an air/oil mixture. The present invention takes advantage of this discovery to communicate a first higher expected flow source to the drive gear, and to separately communicate a second, relatively lower expected flow rate to the driven gear. A particular application is in a scavenging pump for a jet engine.
