Abstract
An oil accumulator assembly may comprise a scavenge tube including an aperture defined by a break in the scavenge tube and/or an annular cylindrical structure concentrically situated about the scavenge tube. The aperture may be configured to receive oil flowing through the scavenge tube, and the annular cylindrical structure may be configured to accumulate oil flowing through the aperture. The oil accumulator assembly may further comprise a drainage outlet disposed in the annular cylindrical structure. Oil accumulated within the annular cylindrical structure may drain through the drainage outlet in response to an engine being shut down. The oil accumulated within the annular cylindrical structure may fill a portion of the scavenge tube situated within an engine fan case to prevent coking within the scavenge tube.
