An apparatus for axially transferring fluid may comprise an elongated shaft defining a first fluid passageway axially therethrough and a second fluid passageway from an outer surface thereof to the first fluid passageway. An elongated tube member defines an outer surface that is received within the first fluid passageway and a third fluid passageway axially therethrough. A plurality of axial channels are defined between the tube member and the first fluid passageway or along the tube member separately from the third fluid passageway. At least one of the plurality of axial channels define a first opening near one end thereof that receives fluid from a source of fluid and a second opening axially spaced apart from the first opening and that aligns with the second fluid passageway such that fluid may be transferred by the at least one fluid passageway from the source of fluid through the second fluid passageway.

Apparatus and method for axially transferring fluids to a plurality of components

Provided are stir-welded rotors and methods of making these. An exemplary stir-welded rotor may include a stack of laminations that each has spaced-apart slots arrayed on an outer circumference. The slots register with slot bars that each has a first extremity extending above the stack of laminations and a second extremity extending below the stack of laminations. A first weld extends between first extremities of adjacent slot bars, and a second stir weld extending between adjacent second extremities of adjacent slot bars.
