Patent number: 11692483Abstract: A system for lubricating components of a gas turbine engine includes a supply pump to pump lubricant from a reservoir through a supply conduit to lubricated component. An outer body deicing circuit is fluidly coupled in series with the supply conduit. Moreover, a scavenge conduit extends from the lubricated component to the reservoir and a scavenge pump pumps the lubricant from the lubricated component through the scavenge conduit. In addition, a valve is fluidly coupled in series with the supply conduit and the scavenge conduit and a bypass conduit extends from the valve to a location on the supply conduit downstream of the deicing circuit. When the lubricant is supplied to the valve, the valve directs the lubricant flowing through the scavenge conduit into the reservoir. When the supply of lubricant to the valve is halted, the valve directs the lubricant flowing through the scavenge conduit into the bypass conduit.Type: GrantFiled: July 20, 2022Date of Patent: July 4, 2023Assignee: GENERAL ELECTRIC COMPANYInventors: James John Luz, Robert Burton Brown, Thomas Bradley Kenney, Thomas Charles McCarthy, Firas Younes

Patent number: 11199103Abstract: A seal assembly for a turbomachine. The turbomachine includes a rotating shaft extending along a centerline and a fixed housing positioned exterior to the rotating shaft in a radial direction relative to the centerline. The seal assembly includes a sump housing at least partially defining a bearing compartment for holding a cooling lubricant. The seal assembly further includes a bearing supporting the rotating shaft. In addition, the seal assembly also includes a sump seal at least partially defining the bearing compartment. A pressurized housing of the seal assembly is positioned exterior to the sump housing and defines a pressurized compartment to at least partially enclose the sump housing. Further, a non-contacting carbon seal is positioned between the rotating shaft and the fixed housing to at least partially define the pressurized compartment to enclose the sump housing.Type: GrantFiled: September 6, 2018Date of Patent: December 14, 2021Assignee: General Electric CompanyInventors: Scott Francis Wolfer, Kevin Richard Crain, Jonathan K. Remer, Robert Burton Brown, Nicholas Rowe Dinsmore

Patent number: 6439772Abstract: A rotor assembly for a gas turbine engine including a bearing assembly and a damper sub-assembly that facilitate reducing dynamic motion to the rotor assembly is described. The bearing assembly includes rolling elements positioned between a paired race. The rotor assembly includes a rotor shaft supported by the bearing assembly. The damper sub-assembly is radially outward from the bearing assembly adjacent a sump housing, and includes a damper insert. A predetermined preload force is applied to the rolling elements. An outer race of the bearing assembly distorts to substantially match a distortion pattern of the damper insert.Type: GrantFiled: December 1, 2000Date of Patent: August 27, 2002Assignee: General Electric CompanyInventors: Peter Carl Ommundson, Robert Burton Brown, Scott Albert Tardanico
