摘要
A dual circuit lubrication device for lubricating a mechanical system, the lubrication device being provided with two independent lubrication circuits and a tank that is common to both lubrication circuits and that contains a lubrication liquid. A first lubrication circuit has two first suction points for sucking in the lubrication liquid and situated inside the tank, and a second lubrication circuit includes a second suction point for sucking in the lubrication liquid and situated inside the tank. The dual circuit lubrication device has means for detecting the lubrication liquid passing below a limit depth in the tank, which means are formed by a high first suction point situated at the level of the limit depth, the second suction point being situated below the limit depth, and a low first suction point being below the second suction point.
