A method and apparatus for scavenging lubricant is disclosed herein. In the invention, a rotating structure is encircled within a sump housing and subjected to lubrication. The sump housing collects high-momentum lubricant flow and low-momentum lubricant flow. The interior of the sump housing is separated into a plurality of chambers with at least one dynamic seal. The at least one dynamic seal extends between the sump housing and the rotating structure to isolate the high-momentum lubricant flow from the low-momentum lubricant flow.

What is claimed is: 1. A lubrication scavenge system comprising:a structure disposed for rotation about an axis and subjected to lubrication;a sump housing having an inner surface substantially encircling said structure;a first quantity of lubricant disposed on said inner surface having a first level of momentum;a second quantity of lubricant disposed on said inner surface spaced axially from said first quantity and having a second level of momentum less than said first level of momentum; andat least one dynamic seal extending radially between said sump housing and said structure and disposed along said axis between said first quantity of lubricant and said second quantity of lubricant to isolate said first and second quantities of lubricant from one another.
