FIELD: machine building.
SUBSTANCE: annular oil-collecting cover of the gas turbine engine assembly arranged with the possibility of location around the unit and with possibility of rotation around the axis, comprises through holes for radial oil passage due to centrifugal effect, as well as oil deflectors. Oil deviation means are arranged at the outlet of the holes and configured to impart an output velocity oriented in a direction substantially transverse to the axis and substantially tangential, perpendicular to the radial direction, at the level of said outlet. Other inventions of the group relate to a unit comprising a gas turbine engine assembly and said cover, and to a gas turbine engine comprising said cover and/or said assembly.
EFFECT: group of inventions allows limiting oil spillage.
