<p>An oil tank is constructed having a perforated funnel therein. Oil scavenged from the engine is delivered by a tube to an opening in the small bottom of the perforated funnel. The delivery tube passes over the large elongated open top of the funnel acting as a cover means and deflector. As the oil passes through this funnel in a direction of increasing cross sectional area its velocity is reduced. Large air bubbles escape directly to the top of the funnel and smaller air bubbles are strained out as the oil passes through the perforations in the funnel. The oil then passes through a baffle device below the perforated funnel to a small compartment in the bottom of the tank. An outlet in this chamber directs deaerated oil to the engine main pressure pump. In some installations the top of the funnel could follow closely the shape of the tank at that point and even be attached to the tank, so that all oil would have to pass through the perforations.</p> |
