主权项 1. A vacuum pump comprising: a housing; a bearing arrangement; a rotor supported by the bearing arrangement for rotation relative to the housing; a lubricant reservoir that extends about an axis of rotation of the rotor, wherein the lubricant reservoir stores lubricant for lubricating a rolling bearing of the bearing arrangement, and wherein the lubricant reservoir comprises a fibrous annular substrate having voids within which the lubricant is stored; and a brush for transferring lubricant from the lubricant reservoir to the rotor, the brush comprising a set of bristles held by the lubricant reservoir, wherein bristles of the set of bristles extend into at least some of the voids, and wherein bristles of the set of bristles held by the lubricant reservoir come into contact with lubricant within the lubricant reservoir.
