Beschreibung
Zusammenfassung:	A device lubricates elements of an accessory drive system of an aircraft. The device includes a pinion having a pinion shank that is hollow and that has an axis of rotation, a shaft arranged inside the pinion shank and extending along the axis of rotation, a space between the shaft and the pinion shank allowing displacement of oil, an oil reservoir arranged facing the space, at a first end of the pinion shank, and an oil outlet duct arranged facing the space, at a second end of the pinion shank. The pinion shank and the shaft together form a pump and cooperate to drive the oil from the reservoir toward the oil outlet duct thanks to the rotation of the pinion shank around the shaft.
