Patent abstract
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.
