A tank defines an inner cavity and at least an opening. A filler tube device comprises a tube passing through the opening in the tank, the tube forming a joint with at least one degree of freedom with the tank such that the tube is displaceable relative to the tank. The tube has an open end in the inner cavity of the tank, and an opposite open end outside of the tank, whereby the tube defines a passage for filling the tank. A sealing component is in the inner cavity of the tank, the sealing component configured for collaborating with the open end of the tube when the tube is moved into engagement therewith to close the open end of the tube inside the tank in a protective position.

1. An assembly comprising: a tank defining an inner cavity and at least an opening;a filler tube device comprising a tube passing through one of the at least an opening in the tank, the tube forming a joint with at least one degree of freedom with the tank such that the tube is displaceable relative to the tank, the tube having an open end in the inner cavity of the tank, and an opposite open end outside of the tank, whereby the tube defines a passage for filling the tank; anda sealing component in the inner cavity of the tank, the sealing component configured for collaborating with the open end of the tube in the tank when the tube is moved into engagement therewith to close the open end of the tube inside the tank in a protective position, the sealing component being a block having a receptacle extending from an opening into the block to an end in the block, the receptacle for receiving the open end of the tube in the protective position, the tube having its open end opened inside the tank when moved out of engagement with the receptacle. 2. The assembly according to claim 1, wherein the at least one degree of freedom is a translational degree of freedom, such that the tube is slidingly displaceable from the protective position to a filling position in which the open end in the tank is open to the inner cavity. 3. The assembly according to claim 2, wherein the at least one degree of freedom further comprises a rotational degree of freedom about a longitudinal axis of the tube, and further wherein a filling adapter is mounted to the open end of the tube outside of the tank, an orientation of the filler adapter being adjustable by rotating the tube about the rotational degree of freedom. 4. The assembly according to claim 3, wherein the filling adapter has an elbow-type body. 5. The assembly according to claim 3, further comprising a cap releasably secured to an open end of the filling adapter. 6. The assembly according to claim 1, further comprising a venting system comprising at least one conduit having a first end in fluid communication with the sealing component, and a second end being open to the inner cavity of the tank above at least one threshold liquid level of the tank, with the tube being below the at least one threshold liquid level of the tank. 7. The assembly according to claim 6, wherein the venting system comprises a liquid reservoir between the first end and the second end. 8. The assembly according to claim 7, wherein the at least one conduit extends from the first end to the liquid reservoir, and further wherein a diameter of the at least one conduit from the first end to the liquid reservoir is greater than a diameter of the second end. 9. The assembly according to claim 8, wherein the second end is an exhaust port in the liquid reservoir. 10. The assembly according to claim 6, wherein the second end of the venting system is open to the inner cavity of the tank above a first of the at least one threshold liquid level of the tank defined for a horizontal orientation of the tank, and above a second of the at least one threshold liquid line of the tank defined for a vertical orientation of the tank. 11. The assembly according to claim 1, further comprising a bayonet system between the tank and the open end of the tube outside of the tank to releasably lock the tube in the protective position. 12. The assembly according to claim 1, further comprising an adaptor tube interfaced between a first one of the at least an opening of the tank and the tube, the adaptor tube forming the joint with the tube. 13. The assembly according claim 12, wherein the adaptor tube comprises a receptacle outside of the tank, and further wherein the filler tube device comprises a flange outside of the tank, the receptacle accommodating the flange to releasably lock the tube in the protective position. 14. The assembly according to claim 13, further comprising a biasing device in the receptacle to bias the flange against a surface of the receptacle to releasably lock the tube in the protective position. 15. The assembly according to claim 1, wherein the at least an opening comprises two said openings, and wherein the sealing component comprises a first portion adapted to close the open end of the tube in the tank if mounted to a first one of the openings, and a second portion adapted to close the open end of the tube in the tank if mounted to a second one of the openings. 16. The assembly according to claim 15, further comprising a blanking cover to block the one of the openings if it is without the tube. 17. The assembly according to claim 15, further comprising a plug secured to one of the first portion and the second portion corresponding to the one of the openings if it is without the tube. 18. A gas turbine engine comprising: a nacelle defining an inner volume, and a door to access the inner volume; andthe assembly according to claim 1 in the inner volume of the nacelle, the one of the at least an opening of the tank and the open end of the tube outside of the tank being aligned with the door such that an end of the filler tube device is displaceable to a filling portion outside of the nacelle. 19. The gas turbine engine according to claim 18, wherein the gas turbine engine is a tilt rotor.
