Abstract
A lubricant system for supplying lubrication to a component in a turbine engine includes a lubricant reservoir, a supply line fluidly coupling the lubricant reservoir to the component in the turbine engine, a scavenge line fluidly coupling the component to the lubricant reservoir, and a bypass line fluidly coupling the supply line to the scavenge line and bypassing the component.
Claims20
A lubricant system for supplying lubrication to a component in a turbine engine, the lubricant system comprising:
- a lubricant reservoir;
- a supply line fluidly coupling the lubricant reservoir to the component in the turbine engine;
- a scavenge line fluidly coupling the component to the lubricant reservoir;
- a bypass line fluidly coupling the supply line to the scavenge line and bypassing the component;
- a first sensing position providing a first output indicative of a first lubricant parameter in the supply line;
- a second sensing position providing a second output indicative of a second lubricant parameter in the scavenge line;
- and
- a bypass valve fluidly coupled to the first sensing position and second sensing position and controlling a flow of lubricant through the bypass line based on the first and second outputs.
5 more elements
A turbine engine, comprising:
- a compressor, combustor, and turbine in axial flow arrangement;
- a shaft operably coupled to at least one of the compressor, combustor, or turbine;
- a lubricated component operably coupled to at least one of the compressor, combustor, turbine, or shaft;
- and
- a lubricant system fluidly coupled to the lubricated component and comprising:
- a lubricant reservoir;
- a supply line fluidly coupling the lubricant reservoir to the lubricated component;
- a scavenge line fluidly coupling the lubricate component to the lubricant reservoir;
- a bypass line fluidly coupling the supply line to the scavenge line and bypassing the lubricated component;
- a first sensing position providing a first output indicative of a first lubricant parameter in the supply line;
- a second sensing position providing a second output indicative of a second lubricant parameter in the scavenge line;
- and
- a bypass valve fluidly coupled to the first sensing position and second sensing position and controlling a flow of lubricant through the bypass line based on the first and second outputs.
