Tank suitable for holding liquids

摘要

An oil tank suitable for an aircraft mounted gas turbine engine is divided into three series connected chambers. Aerated oil after engine use is fed into the first chamber and de-aerated oil withdrawn from the third chamber for engine use. The chambers are interconnected in such a manner that when the tank is inverted, a reservoir of oil is retained within the third chamber to provide a continued supply of oil to the oil outlet for a finite time period and insufficient oil flows into the first chamber from the second to obstruct an air vent provided in the first chamber.
