Abstract
Disclosed is a device for lubrication of a unit turning under vacuum, such as a flywheel, where the unit includes an axle rotating relative to a fixed bearing structure, via at least one bearing or roller, and where the unit is placed in an enclosure connected to a vacuum, with: a lubricant reservoir connected by pipes both to the bottom of the enclosure and also to the bearing; and fluid suitable circulator for connecting the reservoir either to the vacuum, for filling the reservoir from the enclosure by gravity, or to the atmosphere for lubricating the bearing. The fluid circulator includes a three-way valve connecting the reservoir either to the vacuum or to the atmosphere.
