A combined sump structure in an engine, the combined sump structure comprises a sump area comprising one or more sumps, a single oil supply provided for all sumps, and a combined sump drain.
Claims20
A combined sump structure in an engine, the combined sump structure comprising:
- a sump area comprising one or more sumps;
- a single oil supply for all sumps;
- and
- a combined sump drain.
1 more element
A combined sump structure, comprising:
- one or more sump areas with support for bearing assemblies;
- a sump frame assembly comprising a single engine frame member, wherein the combined sump structure is mounted from the single engine frame member in the sump frame assembly using a single oil supply which passes through the one or more sump areas providing oil to lubricant-dependent components;
- a first sump scavenge line which receives lubrication after the lubricant has passed through a lubricant-dependent component to include a first bearing assembly;
- a second sump scavenge line which passes from one of the sump areas through the sump area and out of an engine to a reservoir with a first sump scavenge system;
- and
- independent and combined sump drains for one or more sumps.
3 more elements
A frame assembly, comprising:
- two sumps, wherein the frame assembly is cantilevered from a single engine frame;
- two sump traps, wherein the frame assembly provides simplified routing to the two sump traps thereby providing shared common supply circuits and lines and a common pressurization circuit between the sump traps;
- and
- a scavenged circuit routed from an aft sump area, the scavenged circuit comprising a first sump to a forward sump area and a second sump, wherein the scavenge circuit remains separate from the supply circuits thereby resulting in a system wherein the two sumps are located proximally one to the other.
