Abstract

A sump housing for scavenging lubricant is disclosed herein. The sump housing includes an outer wall defining a chamber. A lubricated structure operable to rotate can be disposed within the sump housing. The sump housing also includes an out-take for lubricant scavenging. The out-take extends across a chordal arc of the chamber. The out-take includes an upstream first portion of the outer wall diverging away from the chordal arc at a first rate. The out-take also includes a downstream second portion of the outer wall opposite the first portion. The second portion diverges away from the chordal arc toward the first portion at a second rate greater than said first rate to define a blunt wall facing the first portion for reducing the likelihood that windage will limit lubricant scavenging.
