Abstract
A sealing system for a turbomachine bearing enclosure includes bearing with a stator carrying a rotor; a seal carried by the stator and surrounding the rotor; an external peripheral groove carried by the stator in the vicinity of the seal for collecting oil which exits the enclosure running along the rotor through the seal and which is centrifuged by the rotor towards this groove; and a drain at the bottom for discharging the oil from the groove. This groove is open towards the inside and is delimited by a base extended by two side walls, the side wall opposite the seal is extended by a skirt oriented obliquely towards the base to delimit a gutter opening towards the base.
