Patent ID: 7938147

Claim:
An apparatus for axially transferring fluid, comprising: an elongated shaft defining a first fluid passageway axially therethrough and a second fluid passageway extending through the elongated shaft from an outer surface of the elongated shaft into the first fluid passageway, an elongated tube member defining a third fluid passageway axially therethrough, the elongated tube member received within the first fluid passageway of the elongated shaft, and a plurality of channels defined by and extending axially along one of the elongated tube member separate from the third fluid passageway and the first fluid passageway between an inner surface of the first fluid passageway and an outer surface of the elongated tube member, one of the plurality of channels defining 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 can be axially transferred by the one of the plurality of channels from the first opening through the second fluid passageway defined through the elongated shaft.
