Abstract
A fluid transfer seal for transferring hydraulic fluid between differentially rotatable components, such as between the stator and rotor of a gas turbine engine. A circumferential channel is formed about the stator with a fluid passageway connecting the channel to a fluid supply reservoir in the stator. An annular seal carrier is positioned within the channel such that opposite sides thereof are in sliding contact with sidewalls of the channel for inhibiting fluid escape around the carrier. Radially outer and inner circumferential slots are formed on the carrier with apertures through the carrier for coupling fluid between the slots. Outer circumferential grooves are formed around the carrier on opposite sides of the outer slot. Seal rings are positioned in the grooves in contact with the carrier and the rotor for preventing fluid escape along the carrier-rotor interface. Both the carrier and seals are provided with reduced land areas at contact points to facilitate radial and axial motion between rotor and stator without loss of seal integrity.
