A lubricant scavenge arrangement provided on a chamber having an outer wall and configured to house a lubricated rotative component for rotation about an axis, the scavenge arrangement being characterised by comprising:
- a substantially elongate channel provided in a substantially arcuate region of the wall, the channel being open to the chamber over substantially its entire length between an inlet end and an outlet end, said inlet end and said outlet end being angularly spaced apart around said axis.
A bearing chamber for a gas turbine engine, the bearing chamber being configured to house a lubricated bearing for rotation about an axis and comprising a lubricant scavenge arrangement, wherein the lubricant scavenge arrangement comprises a swirl chamber in direct fluid communication with the bearing chamber, the swirl chamber extending outwardly from the bearing chamber in an axial direction and having an outlet for fluid connection to a scavenge pipe, the outlet extending substantially radially relative to the axis and being offset axially from the bearing chamber.
