Abstract
A fluid transfer structure for a transmission has a tube disposed in a central bore of a shaft. The shaft and the tube cooperate to provide a feed passage, central of the tube, and a substantially annular lube passage formed between the tube and the central bore. The tube and shaft have cooperating structures that provide proper alignment of the tube in the central bore. A plurality of radial passages are formed in the shaft in communication with the central bore. At least one of the radial passages is in communication with the feed passage which is sealed from fluid communication with the annular lube passage. The remaining radial passages are in limited fluid communication with the annular lube passage. The tube has radially outwardly extending portions aligned with respective ones of the radial passages and cooperate therewith to form flow restriction structures. The extending portions are not fully annular such that free fluid flow is possible along the length of the annular passage.
