Abstract
An oil scavenge system of a rotatable machine having an axis of rotation is disclosed. The oil scavenge system comprises a sump housing, a scavenge conduit, a bearing, and a squeeze film damper. The sump housing is arranged about the axis and at least partly defining a sump. The sump housing has a radially inner surface for directing the flow of oil and defining a collection orifice. The scavenge conduit is in fluid communication with the collection orifice and a downstream location remote from the sump. The bearing is disposed within the sump. The squeeze film damper is positioned proximate the bearing. The squeeze film damper comprises an annular channel and a supply line. The supply line supplies oil to the annular channel. The squeeze film damper further comprises a discharge line. The discharge line is axially aligned with and discharges toward an inner wall of the scavenge conduit.
