Abstract
A turbine engine reservoir has an oil deaerating device. The oil deaerating device includes a deaeration chamber for an air-oil mixture; an inlet of the air-oil mixture with a tangential inlet channel to form a vortex in the air-oil mixture contained in the chamber; and a vent for the discharge of air as a result of the deaeration of the air-oil mixture. The vent includes a rotor driven in rotation by the circulation of the air-oil mixture in the region of the inlet. The rotor filters the degassed air loaded with oil droplets in suspension. By centrifugal force, the rotor returns the collected oil onto the internal surface of the conduit of the vent. The collected oil drops back down into the chamber as a result of gravity.
