Abstract
An adapter is configured to be disposed on the inlet of an oil tank of an aircraft engine. The adapter includes a plug between the adapter and the exterior, and a flapper between the adapter and the oil tank. An adapter cavity located between them is set to negative pressure during flights. When the aircraft is back on the ground, this negative pressure has to be counteracted to open the plug, which can make the opening operation difficult. The adapter includes a lever that counteracts the negative pressure in the cavity of the adapter to allow easy opening of the plug with limited force.
