Abstract
An oil deaeration device for a turbomachine lubrication system, comprising a tank comprising an internal volume with a bottom, an oil outlet on the bottom, and an oil inlet opposite the bottom; an oil deaerator provided at the oil inlet of the tank; and a stabilizing wall arranged in the internal volume facing the bottom and provided with at least one passage for the oil, so as to delimit a volume d stabilized buffer oil.
Claims14
An oil tank for a turbomachine lubrication system, said oil tank comprising:
- an internal volume with a bottom, an oil outlet, and an oil inlet;
- a stabilizing wall arranged in the internal volume facing the bottom and provided with at least one passage for the oil through said stabilizing wall, so as to delimit a stabilized volume of buffer oil;
- wherein the stabilizing wall is fixed to an internal face of a tank wall delimiting the internal volume;
- wherein the stabilizing wall has a diameter defined by a diameter of a peripheral mounting face of the stabilizing wall contacting the inner face of the tank wall, the stabilizing wall being curved to have a dome shape with a concavity of the dome facing the bottom;
- and
- wherein a distance from the stabilizing wall to the bottom is measured parallel to a longitudinal axis of the internal volume between facing surfaces of the stabilizing wall and the bottom, and said distance is equal to or less than 60% of the diameter.
