A device for assisting with the radial distribution of a fluid from a rotating shaft having an axially oriented feed passage opening through an entry, end portion of the shaft and a plurality of discharge ports (P1-P4) spaced axially, and circumferentially, about the shaft to effect communication between the feed passage and the exterior of the shaft. The device is insertably received within the entry end portion of the feed passage. A plug portion is provided to retain flange by being utilized to determine the extend to which the plug portion may be insertably received within the feed passage. An annular constriction is presented from the device, and the constriction is adapted to be located interiorly of, and axially inwardly from, the entry end portion of the feed passage. A flared portion tapers conically outwardly from the constriction and extends inwardly along the feed passage for a predetermined distance to underlie selected discharge ports (P3-P4). The flared portion extends from the constriction to a terminal end portion. A spacer flange extends radially outwardly from the terminal end portion to engage the interior wall of the feed passage. The spacer flange is circumferentially discontinuous to provide at least one back-flow aperture along the exterior of the terminal end portion.
