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.
Claims12
A device configured to be mounted on an oil tank of an aircraft turbomachine, the device comprising:
- a channel located between a device inlet and a device outlet, the device outlet being configured to be connected to the oil tank,
- a plug movably mounted on the device inlet and configured to take:
- a venting position in which fluid can enter the channel through the device inlet, and
- a sealing position in which the plug completely seals the device inlet;
- wherein the device inlet comprises a projection and in that the device comprises a lever connected to the plug;
- the lever comprising a bearing elbow configured to bear on the projection and to pivot about the projection between a projection contact position and a lifting position;
- the plug being in the sealing position when the lever is in the projection contact position,
- the plug being in the venting position when the lever is in the lifting position;
- and
- the lever moving the plug from the sealing position to the venting position as the lever pivots from the projection contact position to the lifting position.
