An assembly is disclosed for automatically balancing thrust on the rotor of a gas turbine engine. An annular chamber axially positioned relative to the rotor is adapted to receive pressurized hydraulic fluid and apply it to the rotor. The force thereby applied to the rotor is regulated by sensing changes in axial rotor thrust and delivering hydraulic fluid to the chamber at a pressure sufficient to balance axial forces acting on the rotor.

In a gas turbine engine, including a rotor supported axially by at least one rotor thrust bearing, means for reducing the axial thrust on said bearing, comprising: (a) an annular, sealed pressure chamber coaxial with the center axis of said rotor wherein said chamber is bounded by a portion of said rotor, a non-rotating member, and sealing means operatively connecting said rotor and non-rotating member, said sealing means positioned as to define a radially outer and inner seal for said sealed pressure chamber; and (b) means for supplying hydraulic fluid to said chamber at a pressure proportional to said axial thrust on said thrust bearing.
