Abstract
A lube system is provided and includes an air-oil tank including a deaerator configured to remove a first quantity of oil from a first air-oil supply to generate a second air-oil supply having a second quantity of oil, which is smaller than the first quantity of oil, the air oil tank being configured to output the second air-oil supply to an air vent line, a de-oiler disposed along the air vent line and configured to remove from the second air-oil supply oil mist including oil droplets of a minimum size and a pressure regulating valve (PRV) disposed along the air vent line between the air-oil tank and the de-oiler to regulate fluid pressures within the air-oil tank, the PRV being configured to encourage formation of the oil droplets of at least the minimum size.
