Patent ID: 8439083

Claim:
An apparatus for axially transferring fluid, comprising: an elongated shaft defining a first fluid passageway axially therethrough, a second fluid passageway extending through the elongated shaft from an outer surface of the elongated shaft into the first fluid passageway, an elongated member defining a third fluid passageway axially therethrough, the elongated member received within the first fluid passageway of the elongated shaft, a fourth fluid passageway extending through the elongated shaft from an outer surface of the elongated shaft into the first fluid passageway, the fourth fluid passageway being axially spaced from the second fluid passageway, the fourth fluid passageway being configured to receive fluid from a source of fluid, 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 aligns with the fourth passageway and a second opening axially spaced 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; and a manifold defining a fifth fluid passageway having one end configured to be fluidly coupled to the source of fluid and an opposite end fluidly coupled to the fourth fluid passageway such that fluid from the source of fluid can flow through the fifth fluid passageway to the at least one of the plurality of channels.
